495XA-493D TDO (Two-Row Double-Outer Race) (Imperial)

495XA-493D TDO (Two-Row Double-Outer Race) (Imperial)

The 495XA-493D is a two-row tapered roller bearing with a 3.25″ bore and 5.375″ outer diameter, built from sturdy chrome steel for long-lasting performance. It handles combined loads with a dynamic radial capacity of 60,500 lbf and operates smoothly in temperatures from -30°C to 110°C.

Its double-row design provides extra stability, while the open seal allows for easy lubrication. The bearing comes with standard radial clearance but can also be ordered in C3, C4, or C5 grades for specific needs.

This model is ideal for heavy-duty applications like truck axles or industrial gearboxes where high radial and thrust loads are common. Weighing 7.62 lb, it’s robust yet manageable for its size.

Compliant with RoHS and REACH standards, it’s a reliable choice for replacements or new installations. The ABEC-1 rating ensures consistent performance for general industrial use.
