32928

The 32928 is a single-row metric tapered roller bearing, a fundamental component engineered to effectively manage high levels of combined radial and axial loads. Its design, featuring tapered rollers and raceways, ensures excellent stability and rigidity, making it indispensable in demanding applications across heavy industry, such as in gearboxes, automotive differentials, and cone crushers. The unit is typically composed of two separable parts: the cone assembly (inner ring, rollers, and cage) and the cup (outer ring), which simplifies both mounting and maintenance procedures. Standard dimensions for the 32928 bearing are 140 mm inner diameter, 190 mm outer diameter, and 32 mm total width, confirming its position as a heavy-duty, reliable choice.

This specific tapered roller bearing is recognized for its impressive load ratings; for instance, static radial ratings often exceed 395,000 N (depending on the manufacturer, such as SKF or Timken), ensuring durability under significant stationary forces. Due to its single-row configuration, the 32928 can only accommodate axial loads in one direction. Consequently, it must be mounted in opposition to a second tapered roller bearing-typically in an 'O' or 'X' arrangement-to handle axial loads from both directions and to allow for proper operational preload adjustment. Its robust construction, usually featuring a stamped steel cage, contributes to its long service life and high operational efficiency under various speed and temperature conditions.
