21310 Spherical Roller Bearing | High Load Self-Aligning Bearing
The 21310 spherical roller bearing is a high-performance self-aligning rolling bearing designed for heavy radial loads and moderate axial loads. It features superior self-aligning capability to offset shaft misalignment and mechanical deflection, with low friction, stable rotation and excellent anti-vibration performance. Supplied in GCr15 bearing steel and stainless steel options, the 21310 bearing delivers stable precision and long service life in standard, humid and mildly corrosive industrial environments.
Material Introduction
Bearing Steel (GCr15): GCr15 high-carbon chromium bearing steel is the standard material for 21310 bearings. With professional heat treatment, it achieves high hardness, excellent wear resistance and strong fatigue resistance. It ensures long-term stable heavy-load operation and high rotational accuracy, offering outstanding cost performance for general heavy industrial machinery.
Stainless Steel: Stainless steel 21310 bearings provide excellent rust-proof, anti-oxidation and weak corrosion resistance. They effectively resist moisture and minor industrial contamination, avoiding precision loss and premature bearing failure, perfectly suitable for damp, sanitary and clean working scenarios.
Product Features
Powerful self-aligning performance compensates for shaft deviation and misalignment. High radial load capacity with reliable moderate axial load tolerance. Low friction, low noise and strong anti-vibration stability. Dual material grades adapt to conventional and anti-corrosion working conditions. Durable structure with long service life and wide equipment compatibility.
Application Scenarios
21310 spherical roller bearings are widely used in mining machinery, industrial fans, conveyor systems, construction equipment, agricultural machinery and heavy-duty transmission systems. Standard GCr15 models fit conventional heavy industrial equipment, while stainless steel versions are ideal for food machinery, medical devices and high-humidity working environments.
