INSTALLATION:

1. Punch or drill and ream a hole of diameter A 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!
