Miki Pulley ETP Bush

Miki Pulley ETP Bush uses an original hydraulic system that connects with just a single bolt. The shaft and hub are coupled through friction instead of relying on keys, so you avoid the usual problems that come with key type couplings. Since the design is simple, mounting and removal are easy, and it can position and index accurately, which cuts down a lot of work at the design, assembly, calibration, and maintenance stages.

There are several models to choose from depending on what your setup needs. ETP-E Plus is quick to install and reaches a concentricity of 0.02mm, making it a good fit for jobs that need frequent removal and reinstallation. ETP-T offers even higher precision at 0.006mm concentricity and works well where you need to position things accurately in both rotation and axial directions. ETP-E is similar to ETP-T but with slightly less precision at 0.02mm. ETP-A tightens using a clamping bolt on the flange surface and reaches 0.05mm concentricity with fewer bolts needed overall. ETP-H is built for much larger loads, using hydraulic pressure to move a built in taper piston, and it handles bore sizes from 50mm to 220mm.
