* iametral clearance after installation theoretically can range rather widely if all contributing bearing, housing,
D
and shaft tolerances are at either of their extremes.
Listed shaft and housing diameters are for steel supports with standard bearing diametral clearance.
Recommended shaft and housing diameters can change greatly based on orientation, temperature, speed, nonstandard diametral clearances, and desired performance characteristics. Contact KAYDON for design assistance
when required.
All dimensions in inches.
