FAQ

What are the main advantages of a bimetal bearing like the BM 505515?

Bimetal bearings offer a great combination of high load-bearing capacity due to their steel backing and excellent self-lubricating, low-friction properties from the PTFE sliding layer. This makes them ideal for maintenance-free applications.

Is this bearing suitable for high-speed rotational applications?

No, this type of bearing is optimized for high-load, low-speed, or oscillating movements. For continuous high-speed rotation, a ball or roller bearing would be more appropriate.

What kind of shaft tolerance is recommended for a 50mm inner diameter bush?

For optimal performance and press-fit, it is generally recommended to use a shaft with an h-tolerance (e.g., h8 or h9). However, always consult the specific application and manufacturer’s guidelines for precise recommendations.
