  • Bearing selection for low-speed applications | Kaydon ...

    Low-speed bearings defined. The dynamic conditions dictating the bearing design are indicated by the linear speed at the bearing pitch line, or the pitch line speed. Pitch line speeds of less than 500 fpm are generally considered low speed, and 500 fpm to 3,000 fpm are mid-range. Anything higher than 3,000 fpm is considered high-speed.
