385A Single Cones (Imperial)

The 385A single cones are imperial-sized tapered roller bearings with a 2-inch bore, designed for combined loads. Made from durable chrome steel, they handle dynamic radial loads up to 24200 lbf and operate smoothly in temperatures from -30°C to 110°C.

Their open design allows easy maintenance, while the steel cage ensures reliable performance. The bearings come in various part numbers, making them versatile for different setups.

These cones are interchangeable with Timken models, ideal for replacements in industrial machinery or heavy equipment. Their standard radial clearance can also be customised to C3, C4, or C5 if needed.

With an ABEC-1 rating, they offer good precision for general applications. Compliant with RoHS and REACH standards, they’re a safe and practical choice for engineers and maintenance teams.
