Product Introduction
The 28150/28300 is a versatile inch-series tapered roller bearing engineered around a 38.1 mm (1.5-inch) inner bore and a 76.2 mm (3-inch) outer diameter. Measuring precisely 38.1 x 76.2 x 20.638 mm, this cup and cone assembly provides balanced structural stability for moderate to high combined radial and thrust loads. Produced in advanced automated grinding facilities using top-tier chrome alloy steel, the 28150/28300 ensures strict alignment control and minimized running drag, making it highly reliable for international auto parts distributors and mechanical OEMs.
Applications
Automotive gearboxes, differentials, and drive axles.
Agricultural machinery PTO shafts and implement hubs.
Light industrial conveyor pulleys and speed reducers.
