Zero-Max ETP Shaft Locking Bushings Provide the Solution In Static Locking Applications

Apr 26, 2017

Every setup operator’s goal when preparing a tool setup is to load, locate, lock and operate the setup in seconds without problems. The challenges are basically the same whether setting up a machining center or power transmission system. A static application can have the same demands as dynamic. The setup steps for both must be simple – the fewer components, the better. And the locating and locking process must be very precise and equally repeatable so the system startup is flawless from the get-go.
            Enter ETP, the clever setup and shaft locking device that is an ideal solution for both dynamic and static applications. It’s no secret that a jig that facilitates tool and fixture changes saves time and money. The challenge is to find the right way to do it. The extremely simple, yet versatile ETP is adept at handling both dynamic and static applications while saving time, trouble and money in the process. In today’s ever-changing manufacturing industries where more is demanded of less, reducing setup time at the front-end of a production job is the best place to start. ETP provides that front-end improvement.

No Axial Movement When Tightened

            The ETP is essentially a precision bushing that will accurately expand both the ID and OD at the same time when the single actuation screw is tightened.  Since the expansion is caused by the self-contained hydraulic pressure, the resulting force is even along all surfaces.  The bushing aligns precisely without axial movement as it is tightened. It positions very accurately in seconds.
            Another key ETP feature is that it can be actuated thousands of times with repeatable accuracy and without any axial movement.  An Allen wrench is all that is required to mount and lock these bushings into place. They have sealed, clean lines that resist debris collection and clean easily without any special maintenance.

A Full Range of Inch And Metric ETP Sizes Including Stainless Steel Models Available Off-The-Shelf

            ETP is available in several models to fit the application. The ETP Express and Techno models both feature a single actuation screw. The Express handles a torque range from 40 to 6400 ft. lbs. while the Techno handles a torque range from 28,000 to 32,000 ft. lbs. Sizes available handle 15mm through 100 mm shafts with both operating well in temperature ranges from -22° to +180°F.
