X-treme Performance – Value-Engineered for 1/2 to 25 HP drives
POSISTOP X-CLASS BRAKE OPTIONS
Manifold Mounted Valve
Add the convenience and performance of a Manifold Mounted Valve. Mounting the valve directly on the unit eliminates extra plumbing, improves response time, increases cycle rate, and improves positioning accuracy.
The Posistop® X-Class oil shear motor and coupler brakes are designed and tested to operate over 20 million trouble-free cycles with only occasional oil changes and no adjustment – ever! This is a true dynamic stopping brake, not just a holding brake.
This unheard of life expectancy allows the Posistop® X-Class motor and coupler brakes to be used on applications previously thought impossible to do using a brake. Dust, dirt,or moisture is no problem with our IP56 rated housings! Smooth running, quiet engagement and many options such as vertical orientation, horizontal orientation, foot mounting, extended input shaft, manifold mounted valve and many more.
The Posistop X-Class Brake is a direct replacement for many dry friction brakes such as Stearns®, Dings®, Nexen® and Warner® used in packaging, food processing, and production machine applications.

Typical Industry Applications:
- Packaging
- Food Processing
- Meat Packing
- Dynamite/Gun Powder
- Production Machines
Clamped-Split-Quill Shaft Connection System
An innovative Clamped-Split-Quill stops play that could deform the key and keyway in high-torque, high cycle applications. The new clamp design splits the input quill four ways at 90° intervals. A clamp collar fits over the quill to give 360° clamping effect when tightened down. The keyway is centered in one of the splits in the quill to securely lock the key on both sides.
