S Bearings, EZO bearings, Bearing Relubriion Services - What are the temperature limits for ball bearings?

However, bearings can have a nylon or polyamide retainer which can limit the upper temperature to 100°C - 120°C depending on material. Bearing shields will cope with the same temperatures as the rings and balls but rubber seals should not be used above 110°C. The next limiting factor can be the lubricant.

Ball Bearings Selection Guide: Types, Features, Appliions | …

20/1/2022· Ball bearings are used to provide smooth, low friction motion in rotary appliions. Ball bearings are able to provide high performance and long lifetime in order to transfer the load from the balls to the inner races. The balls have minimal contact with the inner and outer races due to their spherical shape and this allows them to spin smoothly.
