33275 Single Cones (Imperial)

33275 Single Cones (Imperial)

The 33275 single cone is a tapered roller bearing with a 2.75-inch bore, designed for combined loads. Made from durable chrome steel, it handles radial loads up to 31100 lbf and fits Timken-compatible systems.

Its open design allows easy maintenance, while the steel cage ensures reliable performance. The bearing operates smoothly in temperatures from -30°C to 110°C, making it versatile for various conditions.

This model is part of the 33000 series and comes with standard radial clearance, though C3/C4/C5 options are available. It’s ideal for heavy-duty applications like truck axles or industrial gearboxes.

Compliant with RoHS and REACH standards, it’s a practical choice for replacements or new installations. The compact design (1.1875-inch width) balances strength and space efficiency.
