Bearings play an important role in just about everything that moves – from fans and roller skates to ATVs and hospital beds. As a manufacturer, CCTY Bearing fields a lot of questions about bearings and bearing assemblies.
Below are the most common bearing questions we receive:
1 What type of bearing grease do you recommend?
It all depends on the application. Grease is an important component to the life of a bearing, so getting it right is vital to the overall performance.
Below are factors to choose a proper grease:
- Environment temperature
- Working temperature
- Bearing speed
- Working Load
- Is shaft vertical or horizontal?
- Is it possible that water will get into the bearing?
Once the particulars about the application are decided, the right grease recommendation can be made.
2 What is the difference between a ZZ and 2RS?
ZZ means that there is a shield on each side of the bearing. ZZ is non-contact type of bearing, so it is applicable to high speed applications.
2RS means that there is a seal on each side of the bearing. 2RS is a contact lip seal, so it has better seal performance and more friction than ZZ type.
3 Can more than one type of bushing fit an application?
Yes. The key is finding the best fit.
4 Can a bushing replace a bearing?
Yes. For example, a TSA bushing may replace a needle roller bearing. Ask a bearing expert to see if there is a bushing alternative for your application.
5 Should I use a sealed spherical plain bearing in an application?
Yes. A sealed spherical plain bearing is always recommended if there are no extra seals outside of the spherical plain bearing.
