Jiayu high precision cylindrical roller bearings are designed specifically to deal with radial loads in applications that require high running accuracy.
Jiayu high precision cylindrical roller bearings are a key components in the engineering applications, because of their exceptional load-carrying capacity and robustness.
The features of high precision cylindrical roller bearing
- High speed capability
- High radial load carrying capacity
- High rigidity
- Low friction
- Low cross-sectional height
Jiayu design and manufacture single row( N10 series) and double row(NN30 series) high precision cylindrical roller bearings.
Material of high precision cylindrical roller bearings
The rings of bearings are made of high quality bearing steel or special as customer requirements.The material of cage ,when the diameter of bearing is less than 400mm,steel plate pressed cage is chosen,otherwise,solid cage will be better.
