9378 Single Cones (Imperial)

The 9378 single cones are imperial-sized tapered roller bearings with a 3-inch bore and 2-inch width, crafted from durable chrome steel. They handle combined loads up to 81600 lbf radially and 27700 lbf thrust, making them sturdy for heavy-duty use.

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, suitable for various industrial conditions.

These cones are interchangeable with Timken models, offering a practical replacement option. Ideal for applications like heavy machinery or automotive systems where robust load handling is needed.

Compliant with RoHS and REACH standards, they provide a safe and dependable choice for engineers and maintenance teams. The standard radial clearance can also be adjusted to C3, C4, or C5 for specific needs.
