7312‑B Angular Contact Ball Bearing 60×130×31mm High Speed for Gearbox Pump

• 7312-B is a single-row angular contact ball bearing with 40° large contact angle. Designed to carry combined radial and one-way axial loads, this open-type bearing performs well under high-speed and heavy-load working conditions. Thanks to its large contact angle, it provides stronger axial bearing capacity than standard angle bearings. Manufactured with high-precision bearing steel, it runs smoothly with low noise and stable performance, widely used in various industrial transmission systems.
