Bearing selection for low-speed appliions | Kaydon

As Fig. 1 shows, a low-speed bearing with a pitch line diameter of less than 1.9 inches can rotate as fast as 1,000 rpm. If, on the other hand, the pitch line diameter is much larger—say, 65 inches—the bearing is considered a low-speed bearing only when the angular speed is less than 30 rpm. Figure 1.
