355X-353D TDO (Two-Row Double-Outer Race) (Imperial)

355X-353D TDO (Two-Row Double-Outer Race) (Imperial)

The 355X-353D is a double-row tapered roller bearing with a 1.75″ bore and 3.548″ outer diameter, built from sturdy chrome steel. It handles combined loads with a dynamic radial capacity of 38000 lbf and works in temperatures from -30°C to 110°C.

Its open design allows for easy lubrication, while the steel cage ensures durability. The bearing comes in standard radial clearance but is also available in C3, C4, or C5 options for different fits.

This model is ideal for heavy-duty applications like axles or industrial gearboxes where both radial and thrust loads are present. Weighing 3 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 decent precision for general industrial use.
