30211 bearing

The 30211 single row tapered roller bearing is engineered with a metric 55mm bore, 100mm outer diameter, and a 22.75mm total width, making it a highly reliable component for heavy-duty industrial and automotive setups. Featuring precisely crowned conical rollers guided by the inner ring rib, the 30211 bearing distributes structural stress evenly across contact surfaces to eliminate edge loading and handle substantial, simultaneous radial and axial forces. Because the cup and cone are completely separable, this versatile 30211 assembly simplifies mounting, adjustment, and routine inspection on the shop floor. Its optimized sheet metal cage ensures minimal operational friction and superior thermal stability, allowing the unit to maintain smooth performance even under high-torque, demanding operating conditions.
