Tapered Roller Bearings

Tapered roller bearings are designed to handle combined radial and axial (thrust) loads efficiently. Their conical rollers and raceways are precisely angled to distribute loads evenly, reducing friction and wear. The separable design allows for easy mounting, disassembly, and adjustment of clearance. Widely used in automotive wheel hubs, gearboxes, heavy machinery, and industrial equipment, these bearings offer high durability and load capacity. Proper lubrication and alignment are critical for optimal performance. With their ability to support both unidirectional axial and radial loads, tapered roller bearings ensure reliable operation in demanding applications.
