FB09 is a rolled plain bearing which can be used in special applications and particularly with high forces and slow radial speeds. The plain bearings are low-maintenance and therefore only require initial lubrication. The diamond-shaped lubrication pockets serve as lubricant depots. Compared to traditional bronze plain bearings, these are cheaper and more compact. In addition, the material is corrosion resistant to chemical substances.
Characteristics
High resilience and strength with low wear, suitable for rough operation, corrosion-resistant. – Rolled FB09 plain bearing, with lubricant depots. |
