HH221449XX Single Cones (Imperial)

HH221449XX Single Cones (Imperial)

The HH221449XX is a single-row tapered roller bearing cone with a 4-inch bore, designed for combined loads. Made from durable chrome steel, it handles dynamic radial loads up to 142,000 lbf and operates smoothly from -30°C to 110°C.

Its open design allows easy maintenance, while the steel cage ensures reliable performance. The cone width is 2.265 inches, with precise tolerances for a secure fit.

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

Compliant with RoHS and REACH standards, it offers a balance of strength and durability. The standard radial clearance can also be adjusted to C3, C4, or C5 for specific needs.
