Single Row Cylindrical Roller Thrust Bearings assembly K 81218 TN

Single Row Cylindrical Roller Thrust Bearings assembly K 81218 TN

The K 81218 TN is a single-row cylindrical roller thrust bearing with a 90mm bore and 135mm outer diameter, built to handle heavy loads. Its chrome steel rollers and glass fibre reinforced PA66 cage ensure durability and smooth operation.

This bearing can manage dynamic radial loads up to 52200 lbf and static loads up to 194625 lbf, making it suitable for demanding applications. It operates smoothly at speeds up to 2000 RPM and works in temperatures from -30°C to 110°C.

The design includes separate shaft and housing washers (WS 81218 and GS 81218) for easy installation. Its compact 14mm thickness makes it a space-saving solution for machinery.

Ideal for industrial equipment like presses or heavy-duty gearboxes where high thrust loads are common. Compliant with RoHS and REACH standards, it’s a reliable choice for replacements, interchangeable with SKF bearings. Weighing 0.54kg, it offers robust performance in a manageable size.
