What Are Thrust Bearings and How Do They Work? - Monroe

Apr 20, 2021· Thrust bearings are rotary bearings that are designed specifically to support an axial load. In other words, they are capable of rotating along with a machine’s parts. Thrust bearings, in fact, assist in the rotation of a machine’s moving parts. As a machine’s moving parts begin to rotate, they’ll glide along the thrust bearings.

Double Shield TBM - Herrenknecht AG

In stable rock, the machine is braced radially against the tunnel with the gripper shoes. This means that the front shield can be advanced independently of the gripper shield using the main thrust cylinders. The reaction forces during the excavation process are transferred into the rock by the extended gripper shoes.

S Series - Logan Clutch

They are bearing sup-ported on the mounting hub and are held stationary by the external connection to the inlet port. This bearing allows the separator discs and hub, and the shaft on which it mounts, to rotate about the cylinder and piston. A thrust bearing permits relative motion between the stationary piston and rotating separator discs.
