Product Overview: The 31307 Tapered Roller Bearing
The 31307 bearing is a single-row tapered roller bearing designed to withstand heavy combined (axial and radial) loads. With principal dimensions of 35x80x22.75mm, this component is a key part of our 31300 Series and the broader Tapered Roller Bearings collection. Its design features tapered inner and outer ring raceways and tapered rollers, which allows for true rolling motion and low friction. The separable nature of the cone (inner ring with roller and cage assembly) and the cup (outer ring) simplifies mounting, dismounting, and maintenance procedures.
Engineered for reliability and high performance, the 31307 bearing is a staple in demanding industrial and automotive applications. Its ability to handle significant thrust loads in one direction makes it essential for gearboxes, axle systems, and various machinery where load management and durability are critical. Trust our expertise as a leading supplier to provide high-quality bearings for all your mechanical needs.
Features of the 31307 Bearing
- Combined Load Capacity: Expertly designed to accommodate both high radial and axial loads in a single direction.
- Separable Design: The cone and cup are separable, allowing for easier and more flexible mounting and maintenance.
- Tapered Geometry: Reduces friction and operational temperature by ensuring true rolling contact between rollers and raceways.
