As an official SKF distributor, we provide the Spherical Roller Bearing 21313EK with full traceability documentation, eliminating customs clearance obstacles. Our centralized warehouse ensures stable bulk supply, while 33mm width design makes it ideal for automotive transmission and general machinery applications requiring high radial load capacity.
Engineered for Heavy-Duty Automotive Applications
The SKF 21313EK Spherical Roller Bearing excels in high-load, moderate-speed conditions typical of automotive differential assemblies and industrial gearboxes. Its self-aligning capability compensates for shaft misalignment up to 2 degrees, reducing stress on adjacent components and extending equipment lifespan in harsh operating environments.
Key Technical Features for Reliable Performance
The 21313EK designation indicates SKF's enhanced design with optimized internal geometry for improved load distribution. Its 33mm width provides a robust contact area to handle radial loads common in automotive powertrain systems. Manufactured under ISO 9001 quality standards, this bearing maintains consistent performance across temperature variations, ensuring reliable operation in both under-hood and industrial settings.
