FAS has developed a tool to measure rolling resistance in any type of geared assembly.  These assemblies include: transmissions, gear boxes, differentials, rear end assemblies and pumps.

The tool uses a hand held gun, motor controller, and PC to rotate the input shaft of an assembly.  While your assembly is rotating, the RAD software will provide you with the following benefits:

- Find lost horsepower
The RAD gun measures rolling resistance of gear trains, rear ends, transmissions, pumps or any other geared assembly

- Test Bearing Preload
Too Little Preload = Premature failure
Too Much Preload = Unnecessary rolling resistance and lost horsepower
RAD will help you find the perfect bearing preload and shim pack

- Proper Gear Mesh
Detect hidden wear in gears, lobed gears or bad gear teeth

- Pump Seal Failure
A large change in pump rolling resistance could be caused by a failing seal or worn pump rotor

- R&D Testing
Quantify design or component changes

Are those expensive "low friction" gears really worth it? Use the RAD system to evaluate the efficiency of design and component changes.
