THE USE OF THE BEARING
Some tips on use
Rolling bearing is a precise part. Therefore it should be used carefully. No matter how high performance the bearing has, it can be obtained by improper use, the followings are the points for attention to use bearings.
(1) Keep clean the bearing and its surrounding areas
It is harmful to the bearing even by tiny dust which can not be seen by human eyes. Therefore it should always keep clean the surrounding environments in order to prevent the bearing from dust corrosion.
(2) Use bearing carefully
Scar and indentation can essily be produced out of strong impact to the bearing in use and become the cause of accidents. Therefore special caution should be given to its use.
(3) Use the appropriate operating tool
Avoid using a hammer or heavy direct tap on a bearing or sleeve, must use appropriate tools such as press or heating.
(4) Be careful to the rust corrosion of the bearings
The sweat in the hands will cause rust in operating the bearings. Therefore your hands should be cleanly washed and dried before operation. You’d better wear gloves in doing the work.

Installation Instructions

 Bearing mounting
 Precautions for proper mounting of bearing
1) Bearing preparation
Bearing should not be unpacked until before mounting due to spray anti-corrosion oil and pack anti-corrosion paper. In addition, spray anti-corrosion oil on bearing have good lubricate function. For general purpose, just directly using bearing fill-in grease bearings, without cleaning. However, bearing for instrument or high speed rotating must be cleaned with clean filtered oil in order to remove the anti-corrosion oil. At that time, the bearings are easy to corrosion could not storage long term.
2) Inspection of shafts and housings
Cleaning shaft and housing, confirming no scratched or machine burrs, no CZPT and cutting piece in housing. Secondly comppare with drawing, the shaft and housing of dimension, form and machining quality should be inspected.
chart 1 Measure location for shaft diameter                                                                         chart 2  Measure location for housing bore diameter                       

As chart 1 and chart 2 showing, divided several locations to be measure on shaft and housing bore diameters, It should be careful inspected perpendicular between shaft, housing fillet dimension and shoulder.
Before mounting bearing, it should be sprayed mechanical oil on fitting surface after check out the shaft and housing.

Bearing storage
Before leaving the factory, the bearing is sprayed proper rust-inhibiting oil and packed rust-inhibiting paper. The quality of bearing is guaranteed, if the packing is not broken.
For long-term storage, if the humidity less than 65% and the temperature about 20, it should storage on shelf which is higher 30cm than ground.
In addition, storage occasion should avoid sunshine and contact with cold wall.

How do I replace a shielded bearing?

Replacing a shielded bearing requires careful handling and attention to detail. Here’s a detailed explanation of the steps involved in replacing a shielded bearing:

1. Equipment preparation:

  1. Gather the necessary tools and equipment for the bearing replacement, including appropriate wrenches, bearing pullers, and lubricants.
  2. Ensure the equipment is turned off and all power sources are disconnected.
  3. Follow any safety procedures and wear appropriate personal protective equipment (PPE) as required.

2. Bearing removal:

  1. Identify the location of the shielded bearing that needs to be replaced.
  2. If applicable, remove any external components, such as covers or seals, that may be covering the bearing.
  3. Use the appropriate tools, such as a bearing puller or press, to carefully remove the damaged or worn shielded bearing from its housing. Apply force evenly and avoid causing any damage to the surrounding components.
  4. Inspect the housing and shaft for any signs of damage or wear. Clean the area and remove any debris or contaminants.

3. Bearing installation:

  1. Prepare the new shielded bearing by ensuring it matches the specifications and size of the old bearing.
  2. If necessary, apply a thin layer of lubricant to the bearing’s inner and outer races to facilitate smooth installation.
  3. Position the new shielded bearing into the housing or onto the shaft, aligning it properly.
  4. Apply appropriate force using a press or suitable installation tool to ensure the bearing is fully seated in its designated position. Take care not to apply excessive force, as it can damage the bearing or its surrounding components.
  5. If applicable, reinstall any external components, such as covers or seals, that were removed during the bearing removal process.

4. Post-installation steps:

  1. Clean the area around the newly installed shielded bearing to remove any lubricant or debris.
  2. If necessary, apply the recommended lubricant to the bearing according to the manufacturer’s guidelines.
  3. Perform a visual inspection to ensure the bearing is properly seated, aligned, and secured.
  4. If the equipment has multiple bearings, repeat the above steps for each bearing that needs to be replaced.

How do shielded bearings handle radial and axial loads?

Shielded bearings are designed to handle both radial and axial loads, although the specific load capacities may vary depending on the bearing design and size. Here’s a detailed explanation of how shielded bearings handle radial and axial loads:

Radial Loads: Radial loads are forces that act perpendicular to the bearing’s axis, causing it to rotate. Shielded bearings can handle radial loads by distributing the load evenly across the rolling elements, races, and the bearing’s internal structure. The rolling elements, typically balls or rollers, transmit the load from the outer race to the inner race. The races are the ring-like structures that contain the rolling elements and guide their movement. The distribution of the load helps prevent localized stress and ensures that the bearing can support the applied radial load without excessive deformation or premature failure.

The load-carrying capacity of a shielded bearing under radial loads depends on various factors, such as the bearing’s size, design, materials, and the number and size of the rolling elements. Manufacturers provide load ratings for shielded bearings, which indicate the maximum radial load that the bearing can sustain under specific operating conditions. It’s crucial to consider these load ratings and ensure that the applied radial load falls within the recommended limits to prevent bearing failure.

Axial Loads: Axial loads are forces that act parallel to the bearing’s axis, causing it to move in the axial direction. Shielded bearings can handle axial loads to some extent, but their capacity to resist axial loads is generally lower compared to their radial load capacity. The ability of a shielded bearing to handle axial loads depends on its design, including the type of rolling elements and the presence of additional features such as cages or thrust washers.

In applications with predominantly axial loads, specialized bearing designs like thrust bearings or angular contact bearings may be more suitable. These bearings are specifically engineered to handle higher axial loads and provide enhanced axial load-carrying capabilities.

It’s important to note that the load-carrying capacities of shielded bearings may also be influenced by factors such as the speed of rotation, operating temperature, lubrication, and the presence of any external forces or moments acting on the bearing. Therefore, it’s crucial to consult the manufacturer’s specifications and guidelines to determine the appropriate bearing type and size for a given load application.

By understanding the load requirements of your application and selecting the appropriate shielded bearing with sufficient load capacity, you can ensure reliable and efficient operation while minimizing the risk of premature failure or damage to the bearing.

How does a shielded bearing differ from a sealed bearing?

A shielded bearing and a sealed bearing are two different types of rolling bearings that offer varying levels of protection against contaminants and retention of lubrication. Here’s a detailed explanation of the differences between a shielded bearing and a sealed bearing:

Shielded Bearing:

A shielded bearing incorporates shields made of metal (typically steel or stainless steel) to cover the rolling elements and raceways of the bearing. The shields act as a physical barrier against solid contaminants, such as dust, dirt, or debris, preventing them from entering the bearing. The primary functions of the shields are to protect the internal components from contamination and retain the lubricating grease or oil within the bearing.

Shielded bearings provide moderate protection against contaminants, but they are not completely sealed. They allow for some exchange of air and limited penetration of fine particles. Shielded bearings are suitable for applications where the risk of contamination is moderate and where regular maintenance and relubrication can be performed. They are commonly designated with the suffix “Z” or “ZZ” in the bearing model or part number.

Sealed Bearing:

A sealed bearing, on the other hand, incorporates sealing elements made of synthetic rubber or other materials to provide a more effective barrier against contaminants. The seals are designed to completely enclose the internal components of the bearing and prevent the ingress of solid and liquid contaminants, such as dust, dirt, water, or chemicals.

Sealed bearings offer a higher level of protection and are suitable for applications where the risk of contamination is high or where maintenance and relubrication are more challenging. The seals help to extend the bearing’s service life, reduce the need for relubrication, and provide enhanced protection in harsh or demanding environments.

Sealed bearings are typically designated with the suffix “RS” or “2RS” in the bearing model or part number. The “RS” suffix indicates a single seal on one side of the bearing, while “2RS” indicates seals on both sides.

It’s important to note that while sealed bearings provide superior protection against contaminants, they may generate slightly more friction and heat due to the increased sealing contact compared to shielded bearings. This can result in a slightly lower operating speed or higher torque compared to shielded bearings.

The choice between a shielded bearing and a sealed bearing depends on the specific requirements of the application, including the level of contamination risk, the need for maintenance and relubrication, and the operating conditions. Consulting with bearing manufacturers, distributors, or industry experts can help in selecting the most appropriate bearing type for a given application.

Overall, shielded bearings and sealed bearings are both effective solutions for protecting rolling bearings, and the selection depends on the desired level of protection and the specific application requirements.
