LL483449 Single Cones (Imperial)

LL483449 Single Cones (Imperial)

The LL483449 is a single-row tapered roller bearing cone with a 30-inch bore, designed for combined loads. Made from sturdy chrome steel, it handles dynamic radial loads up to 352,000 lbf and static loads up to 960,000 lbf.

Its open design and steel cage ensure durability, while the tapered rollers provide smooth operation under heavy loads. The bearing works in temperatures from -30°C to 110°C, making it suitable for tough environments.

With an ABEC-1 rating and standard radial clearance, it offers reliable performance for industrial applications. This cone is interchangeable with Timken bearings, ideal for machinery requiring high load capacity and long service life.

Compliant with RoHS and REACH standards, it’s a practical choice for replacements or upgrades in heavy-duty equipment.
