TS (Single Row Tapered Roller Bearings) (Imperial) 441-432

TS (Single Row Tapered Roller Bearings) (Imperial) 441-432

The 441-432 is a single-row tapered roller bearing with a 1.378″ bore and 3.75″ outer diameter, crafted from sturdy chrome steel. It manages combined loads up to 28500 lbf radially and 3600 lbf thrust, suitable for demanding applications.

Its open design and steel cage ensure durability, while the tapered rollers provide smooth rotation. The bearing operates well in temperatures from -30°C to 110°C and requires regular lubrication.

This model is interchangeable with Timken bearings, making it a practical choice for replacements. Ideal for heavy-duty machinery like gearboxes or axles where combined loads are common.

Weighing 2.4 lb, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards for safe use.

The standard radial clearance (also available in C3/C4/C5) offers flexibility for different setups. Its ABEC-1 rating ensures reliable performance for general industrial use.
