For use with Hiwin linear rail and other manufacturers' rail to lock bearings into a fixed position.

NOT INTENDED FOR DYNAMIC BRAKING!

Operation summary: Air supply is normally maintained, and the pneumatic piston compresses the spring. Clamp does not contact rail in this condition. When air pressure is relieved, the spring extends and presses on the wedge-shape actuator. In turn, the wedge actuator applies force to the friction material and it contacts the rail.

Features and Characteristics

  • Compact design
  • High clamping forces
  • Exact positioning
  • Strong axial and horizontal rigidity

Common Applications:

  • Positioning of axes
  • Fixing of vertical axes
  • Positioning of lifting devices
  • Clamping of machine tables
Higher supporting forces possible with PLUS connection


By using a 5/2 (overflow-free) or 5/3 valve it is possible to augment the spring power with pneumatic pressure. By using the "PLUS" connection, the standard clamping force will be increased significantly.

When the PLUS connection (MKS only) is being used, the air-release filter is replaced by connecting a second pneumatic tube (see drawing at right).

The MKS has an opening pressure of 5.5bar. Ports are located on both sides of the brake, and that means that the air connection and the air-release filter can be located in either location to facilitate plumbing for the unit.

Models available to fit virtually all sizes of linear rail by all major manufacturers:

  • Hiwin
  • THK
  • Rexroth Bosch Group
  • Schneeberger
  • IKO
  • INA
  • NSK
  • SKF
  • Star Linear
  • Adapter plate is required in some applications to elevate the height of the brake mechanism to equal that of the bearing/guide.
  • For application information for Hiwin products, refer to charts below. For other manufacturers' rail, please download the PDF document at the bottom of this page or contact us for assistance.
