LL789749 Single Cones (Imperial)

LL789749 Single Cones (Imperial)

The LL789749 is a single-row tapered roller bearing cone with a 66.5-inch bore, designed for combined loads. Made from durable chrome steel, it handles dynamic radial loads up to 473,000 lbf and operates smoothly in temperatures from -30°C to 110°C.

Its open design allows for easy maintenance, while the steel cage ensures reliable performance under heavy loads. The cone is interchangeable with Timken models, making it a practical choice for replacements.

This bearing is ideal for industrial machinery or heavy equipment where combined radial and thrust loads are common. It comes with standard radial clearance but is also available in C3, C4, or C5 options for specific needs.

Compliant with RoHS and REACH standards, it offers a balance of strength and durability for demanding applications. The ABEC-1 rating ensures consistent performance in most industrial settings.
