Timken 33117-92KA1 Tapered Roller Bearing Set

The Timken 33117-92KA1 tapered roller bearing set is a matched single-row metric bearing assembly consisting of the X33117 cone and Y33117 cup. The 92KA1 suffix identifies a factory-matched set to Timken manufacturing specifications and does not change the bearing’s standard dimensions or performance characteristics. This bearing supports combined radial and axial loads while maintaining precise shaft alignment, delivering high load capacity and dependable service life in demanding industrial gearboxes, wheel hubs, conveyors, mining equipment, agricultural machinery, and power transmission systems. The set is separable, with a cone-and-cup design that simplifies installation, adjustment, and maintenance.
