The integration of planetary roller screw into the current ET (ball screw) product allows design engineers to use this technology for applications requiring high loads, high speeds, fast acceleration, and very high resolution, all at a 15x greater life expectancy over ball screws. With thrust capacity to 100KN (22,500 lbf), and a Parker motor and control system, the ETR series arrives at the customer's dock complete and ready to mount.

The Parker ETR Series features a precision planetary roller screw and is available in four profile sizes - 50, 80, 100, and 125 mm.The modular design of the ETR Series allows for seven mounting styles in addition to available custom mounting, which includes a front trunnion mount.
Additionally, the ETR Series features inline or parallel motor mounting.

With a dual direction angular contact, tapered roller bearings, and high load TorlonT anti-rotate bearings, the ETR Series maintains exceptional performance while providing a life expectancy 15 times greater than ball screws.

Additional features include:

·Enclosed tie rod design for structural strength.
·External lubrication ports for bearings and screw.
·Up to 2G acceleration.
·Parker's global drop-in position sensing switches for limit/home, reed and solid state.
·Oil or grease lubrication designed specifically for the application.
