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

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

Operating Temperature:
-30°C to +120°C

NOTE: Hardened steel shaft required.
 

 

INSTALLATION: 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!

SHAFT RECOMMENDATIONS: Shafts should be hardened to HRC 58 to 64 with a 0.4 µm 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!
