What Empirical Rules Apply to Shaft Hardness, Lubrication, and Installation for Needle Rollers?

July 06,2026

1. Shaft hardness <58 HRC ⇒ multiply calculated life by 0.5.

2. Grease: use NLGI grade ≥2, relubricate every 200 hours.

3. Installation: cage guide clearance 0.05–0.10 mm; larger causes squealing.
