Our SM Series Angular Contact Bearings increases speed by approx. 20% compared to our standard “S” series due to a few key differences in the product design.
Top characteristics of the SM Series:
- Lower operating friction & temperatures lead to a longer lifespan.
- Contact angles available in 15° and 25° (custom contact angles available by request).
- Specially crafted inner ring can support an average of 20% higher operational speeds (compared to our standard S Series).
- Supports RPM speeds up to 230,000 (steel) / 287,500 (ceramic).
- ID: 5mm to 120mm
- OD: 14mm to 180mm
- Speed: 13,500 to 287,500 RPM
Our GMN Angular Contact Bearings are manufactured in accuracy classes P4+ (ABEC 7) with P2 (ABEC 9) running accuracy.
