Technical Specification 
.webp "diagram of dsbr metric tapered roller bearings (2)")
The 31314 27314 tapered roller bearing has a 70mm inner diameter and 150mm outer diameter. Known for its strength and load-carrying ability, it is often used in mining machines, gear units, and automotive systems. Its tapered inner and outer raceways help support heavy axial and radial forces simultaneously.
DSBR’s 31314 tapered roller bearing is manufactured with premium GCr15 bearing steel and CNC precision grinding technology. It is widely used in automotive drive shafts, mechanical pulleys, and off-road vehicles. The bearing resists wear and thermal expansion due to its optimized internal geometry and robust construction. It supports both dynamic and static loads, reducing maintenance intervals. Ideal for markets requiring strict tolerances and long-term stability.
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
