General purpose hub to shaft friction connections
ETP-Express is a general purpose locking bush for the connection of hubs/gears/cams/sprockets to shafts. It is particularly easy to set with a single radial screw allowing stepless radial and axial adjustment. The thin wall construction allows compact assemblies. Available for shafts 15 to 100mm.
ETP-Express type R is made from hardened stainless steel suiting food, process and chemical machinery, 15 to 80mm.
Design: ETP-Express consists of a double walled, hardened steel sleeve filled with a pressure medium, and a flange part. In the flange there is a screw and a piston, with a seal for pressure buildup.
Function: When the pressure screw is tightened, the sleeve expands evenly along the shaft and hub and creates a secure connection through friction locking. After the pressure screw is loosened, the sleeve returns to its original position and can be easily removed.
