Technical Specification
With a 50mm bore and 110mm outer diameter, the 31310 27310E bearing provides robust performance for heavy-load applications. Its design minimizes friction and allows for better alignment under dynamic loads. Widely used in industrial transmission, axles, and gear systems.
Built for heavy-duty applications, the 31310 tapered roller bearing offers robust performance in truck axles, trailers, and agricultural gearboxes. DSBR’s advanced production lines ensure tight tolerances and consistent performance. The optimized contact angle and internal geometry reduce friction and enhance load distribution. Whether used in mining vehicles or mechanical drives, this bearing maintains long-term stability and low maintenance requirements, making it a cost-effective solution.
Ideal for heavy-duty applications, they offer:
Excellent capacity for both radial and axial forces
Support for axial loads in a single direction
Reduced friction for efficient, high-speed operation
Durable, replaceable, and service-friendly design
