Needle Roller Pressbearings, Drawn Cup

• Drawn Cup Needle Roller Bearing
• Carbon Steel Retainer, Black Oxide Finish

Features:
• High-speed, high-load
• Major assembly and production savings
• No precision holes required
• Simple quick press-fit installation
• Self-aligning to ±5°

Operating Temperature:
-22°F to +248°F

NOTE: Hardened steel shaft required

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 N, a minimum depth of O and a punch diameter of P, 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!

SHAFT RECOMMENDATIONS:
Shafts should be hardened to Rc 58 to 64 with 16 µin. finish. Shaft ends should have radii or be chamfered.

INSTALLATION NOTES:
1. The punch must be relieved to accommodate protruding insert.
2. DO NOT PRESS BEARING ON INSERT!
