Operating Temperature:
-30°C to +120°C
NOTE:
1. The direction of rotation is when viewed from the serrated end of the bearing.
2. Hardened steel shaft required.


1. Punch or drill and ream a hole of diameter d1 in panel as specified in the Design Parameters table.
DO NOT DEBURR OR BREAK EDGE OF HOLE.
2. Place bearing assembly in hole. The slight interference fit assures centering the assembly in the mounting hole.
3. Using an anvil with diameter d2, a minimum depth of K and a punch diameter of D2, press the bearing assembly into the panel by constantly applying a force of F, per the table, until the assembly is flush with the panel surface.
DO NOT USE HAMMER BLOWS!
