497P-493D TDO (Two-Row Double-Outer Race) (Imperial)

497P-493D TDO (Two-Row Double-Outer Race) (Imperial)

The 497P-493D is a two-row tapered roller bearing with a 3.375″ 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 71,600 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 in standard radial clearance but can also be ordered in C3, C4, or C5 options for specific needs.

With a weight of 7.37 lbs, it’s robust yet manageable for its size. Ideal for heavy-duty applications like industrial gearboxes or construction equipment where high radial and thrust loads are common.

Compliant with RoHS and REACH standards, this bearing is a reliable choice for replacements or upgrades in demanding environments. Its ABEC-1 rating ensures consistent performance for general industrial use.
