ETP Bush

Our original hydraulic system connects with a single bolt. The shaft and hub are coupled by friction without use of keys, so the shortcomings and difficulties of key couplings are solved all at once. Its construction is simple, mounting and removal are easy, and it can accurately position and index. This greatly reduces work from the design stage to assembly, calibration, and maintenance. It can be mounted using a single bolt, and many models are available, including the ETP-T, which meets a concentricity of 0.006 mm.
