26831 Single Cups (Imperial)

26831 Single Cups (Imperial)

The 26831 single cup is an imperial-sized tapered roller bearing component, measuring 2.95″ in backface diameter and 3.4843″ in outer diameter. Made from chrome steel, it’s built to handle typical loads with a standard ABEC-1 precision rating.

Its cup width of 0.8125″ fits snugly in assemblies, while the 0.03″ backface clearance radius helps with proper seating. The cup works in temperatures from -30°C to 110°C, suitable for most industrial environments.

This standard cup pairs with cones like 26878 and 26880, offering interchangeability with Timken equivalents. Ideal for machinery repairs or axle systems where tapered roller bearings are used.

Compliant with RoHS and REACH standards, it’s a reliable choice for maintenance work. The chrome steel construction ensures good durability for everyday applications.
