Single Row Cylindrical Roller Thrust Bearings assembly K 81120 TN

Single Row Cylindrical Roller Thrust Bearings assembly K 81120 TN

The K 81120 TN is a single-row cylindrical roller thrust bearing with a 100mm bore and 135mm outer diameter, designed for heavy thrust loads. Its compact 11mm width makes it suitable for tight spaces, while the chrome steel rollers ensure durability.

This bearing handles dynamic radial loads up to 35100 lbf and static loads up to 141750 lbf, with a maximum speed of 2400 RPM. The glass fibre reinforced PA66 cage provides strength and reduces friction for smoother operation.

Its design includes separate shaft and housing washers (WS 81120 and GS 81120) for easy installation. The bearing performs well in temperatures from -30°C to 110°C, making it versatile for various environments.

Ideal for industrial machinery like gearboxes or presses where high thrust loads are common. Weighing just 0.25kg, it’s a lightweight yet robust solution. Compliant with RoHS and REACH standards for safe use.
