51100 thrust bearing
What is 51100 thrust bearing used for?
The 51100 thrust ball bearing is designed to support axial loads in one direction while maintaining low friction rotation.
It is commonly used in small to medium mechanical systems where space is limited but axial force still needs to be controlled.
When should you choose 51100 instead of other thrust bearings?
You should consider 51100 when:
- Shaft diameter is 10 mm
- Axial load is moderate (not heavy industrial press load)
- Compact structure is required
- Speed requirement is medium to high
- Cost-sensitive design is needed
- 51100 vs 51200 vs 51101 comparison
| Model | Bore (mm) | Outer (mm) | Thickness (mm) | Load capacity | Typical use |
|---|---|---|---|---|---|
| 51100 | 10 | 24 | 9 | Medium | small motors, light machinery |
| 51101 | 12 | 26 | 9 | Medium | slightly larger shaft systems |
| 51200 | 10 | 26 | 11 | Higher | heavier axial load systems |
Typical applications of 51100 bearing
- Small gear reduction units
- Packaging conveyor adjustment systems
- Fitness equipment load support mechanisms
- Electrical actuator positioning systems
- Light industrial rotary assemblies

FAQ
1. Do I need any preload for 51100?
Usually no preload is needed. It works with a small axial clearance. Too much preload will shorten its life.
2. Can it be mounted in vertical position?
Yes, but it depends on how the load is applied. If axial force is stable, vertical use is fine.
3. What kind of lubrication is better?
Grease is fine for most cases. Oil is used when speed is a bit higher or temperature is more stable control.
4. Is there a cage difference that affects performance?
Yes. Steel cage is more common. Brass cage is used when rotation is smoother or temperature is higher.
5. What tolerance grade do you supply?
Standard is normal industrial grade. Higher precision is available if the application needs tighter axial control.
6. How is it usually packed for export?
Neutral packing is standard. For distributors, we can do individual box or logo printing if required.
7. Is 51100 interchangeable with SKF or NSK models?
In most standard sizes, yes. But final fit depends on housing design and clearance, so we always suggest checking drawings.
