The Catalogue HR 1 – Rolling Bearings (INA/Schaeffler) is an encyclopedic reference for engineers, maintenance teams and technical buyers. Beyond a broad overview of bearing families (deep‑groove and angular‑contact ball bearings; cylindrical/tapered/spherical roller bearings; needle bearings and housings), it details life calculations (L10/Lnm), correction factors for contamination and shock loads, fits for shafts/housings and ISO/ABEC tolerances. It also covers lubrication strategies (greases/oils), internal clearance and preload, thermal effects and speed limits to help prevent sizing and mounting errors.
Content overview
- Families, sizes and rating tables for quick selection.
- Tolerances, fits and internal clearance/preload.
- Lubrication, sealing and operating limits.
How to use
- Define loads, speed, temperature and environment.
- Select the suitable family and verify rating life.
- Confirm fits, clearances and lubrication plan.
Best practices
- Never transmit mounting loads through rolling elements.
- Ensure alignment; control preload and sealing integrity.
- Monitor vibration/temperature for predictive maintenance.
