52393-52637DC TDO (Two-Row Double-Outer Race) (Imperial)

52393-52637DC TDO (Two-Row Double-Outer Race) (Imperial)

The 52393-52637DC is a double-row tapered roller bearing with a 3.9375″ bore and 6.375″ outer diameter, built from sturdy chrome steel. It handles combined loads up to 22700 lbf (two-row radial) and 10600 lbf (thrust), making it robust for heavy-duty use.

Its open design allows easy lubrication, while the steel cage ensures durability. The bearing operates smoothly in temperatures from -30°C to 110°C, suitable for varied environments.

This model fits standard 52000 series applications and comes with ABEC-1 precision. Ideal for industrial machinery or vehicle axles where high radial and thrust loads are common.

Weighing 12.94 lb, it’s a solid choice for replacements, compliant with RoHS and REACH standards. The standard radial clearance can be adjusted to C3/C4/C5 if needed.
