30312

The 30312 tapered roller bearing is a heavy-duty metric component specifically designed to handle the punishing combination of radial and axial loads. Built with a 60mm bore and 130mm OD, this bearing utilizes a precisely angled cup and cone setup that excels in high-torque environments. Unlike standard ball bearings, the 30312's line contact between rollers and races provides much higher stiffness and load-carrying capacity. It's a go-to choice for automotive differentials, heavy-duty transaxles, and industrial conveyors where shaft deflection must be kept to an absolute minimum to prevent gear wear.

Reliability in the field comes down to material integrity, which is why our 30312 units are forged from premium, vacuum-degassed chrome steel. This high-purity steel significantly cuts down on subsurface fatigue, even when operating at the thermal limits of heavy machinery. Because the inner and outer components are separable, maintenance teams can easily inspect raceways or adjust end-play during installation-a massive advantage for custom gearbox builds or agricultural equipment repairs. By reducing internal friction through refined surface finishes, the 30312 helps your systems run cooler, quieter, and significantly longer between service intervals.
