1. High Load Precision Roller Bearings Specifications

High-load precision roller bearings require specialized design features to handle extreme pressure. The ISO 76:2006 standard specifies minimum basic static load ratings, while dynamic capacity is calculated using Lundberg-Palmgren theory. Critical parameters include raceway hardness (HRC 58-64), roller crowning (0.020-0.035mm profile), and clearance classes (C2 to C5). Advanced designs incorporate hybrid ceramic rollers (Si3N4) with steel races, achieving 40% higher load capacity than all-steel versions. Proper preloading (typically 0.002-0.005mm interference) ensures optimal stiffness without excessive heat generation. Leading manufacturers like SKF and Timken offer customized solutions for specific PV values (pressure × velocity) up to 3.5 MPa·m/s.
