Zero-Max ETP-3/8 ETP Mini hydraulic keyless bushing with 3/8" bore. Provides a zero-backlash, keyless shaft-to-hub connection for fractional-horsepower applications. The ETP Mini series is designed for compact spaces and light-duty motion control.

ETP-POWER keyless shaft bushings from Zero-Max consist of a double-walled hardened steel sleeve and flange filled with a specially designed pressure medium. The flange contains a single actuation screw piston with a seal that is used to pressurize and maintain pressure in the connection. The design is optimized to provide higher radial load capacity than the other single-screw models. Also, in the flange are two pre-machined bores that can be used to attach ETP-POWER to the mounted components when the connection is not pressurized.
