438W Single Cones (Imperial)

438W Single Cones (Imperial)

The 438W single cones are tapered roller bearings with a 1.75″ bore, designed for combined loads. Made from durable chrome steel, they handle dynamic radial loads up to 28500 lbf and static loads up to 32400 lbf.

Their open design allows easy maintenance, while the steel cage ensures reliable performance. The bearings operate smoothly in temperatures from -30°C to 110°C.

These cones are part of the 435 series and are interchangeable with Timken models. Ideal for heavy-duty applications like industrial machinery or vehicle axles where combined loads are common.

With standard radial clearance and ABEC-1 rating, they offer a balance of precision and durability. Compliant with RoHS and REACH standards for safe use.
