Positorq Dynamometer Load Brakes

Designed for High Torque – Low Speed Load Testing
of Axles, Final Drives, and Transmissions

Whether it’s testing the most complex aircraft system, off road final drives, or tractor transmissions; Force Control has the products for your load testing requirements. Our patented high-torque, low-speed Positorq load brakes are used to simulate real world environments.

Force Control Industries unique Oil Shear Technology provides heat dissipation for high horsepower applications while maintaining a compact profile capable of direct mounting to the drive axle – eliminating additional gearboxes.

In addition, with Oil Shear Technology, disc wear is negligible, allowing long term testing without loss of torque. In fact most Positorq Dynamometer load brakes in service over the past 40 years have required little to no maintenance.
