21305 Spherical Roller Bearing | High Load Self-Aligning Bearing
The 21305 spherical roller bearing is a versatile self-aligning rolling bearing designed to withstand heavy radial loads and moderate axial loads. It features outstanding self-aligning ability, low friction operation and excellent anti-vibration performance, effectively compensating for shaft misalignment and operational deflection. Offered in GCr15 bearing steel and stainless steel options, the 21305 bearing ensures stable, long-lasting precision in standard, humid and mildly corrosive industrial environments.
Material Introduction
Bearing Steel (GCr15): GCr15 high-carbon chromium bearing steel is the standard material for 21305 bearings. With precise heat treatment, it delivers high hardness, superior wear resistance and strong fatigue resistance. It sustains stable rotating accuracy under continuous heavy-load operation, providing reliable and cost-effective performance for various industrial machinery.
Stainless Steel: Stainless steel 21305 bearings possess excellent rust-proof, anti-oxidation and weak corrosion resistance. They effectively resist moisture and minor industrial contaminants, avoiding premature wear and precision loss, making them ideal for damp, sanitary and clean working scenarios.
Product Features
Superior self-aligning performance offsets shaft deviation and misalignment. High radial load capacity with stable auxiliary axial load resistance. Low friction, quiet operation and strong anti-vibration capability. Dual material grades adapt to conventional and anti-corrosion working conditions. Extended service life and broad mechanical equipment compatibility.
Application Scenarios
21305 spherical roller bearings are widely used in industrial fans, conveyor systems, mining machinery, agricultural equipment, textile machines and general heavy-duty transmission devices. Standard GCr15 models fit conventional industrial equipment, while stainless steel versions are suitable for food machinery, medical devices and high-humidity working environments.
