2789A Single Cones (Imperial)

2789A Single Cones (Imperial)

The 2789A is a single-row tapered roller bearing cone with a 1.5625-inch bore, designed for combined loads. Made from durable chrome steel, it handles dynamic radial loads up to 19,500 lbf and static loads up to 23,000 lbf.

Its open design allows for easy maintenance, while the steel cage ensures reliable performance. The cone has a width of 1.01 inches and operates smoothly in temperatures from -30°C to 110°C.

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

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