Automotive test benches create unique challenges.

Test bench applications have unique requirements over standard power transmission lines because

the test bench needs to run at high speeds as well as low speeds with high torque to fully test to the

engine, dynamo or ABS brake system. Most flexible couplings cannot meet both requirements and

are only able to provide the required torque through a larger size, or higher speed through a smaller

size matching the torque produced at the operating speed.

The Rexnord solution.

The BSD Modulflex Disc Coupling uses interference-fit bolt joints and carbon fiber shafts for

automotive engine test benches. The lightweight carbon fiber and the interference-fit bolt joints

offer higher speed and torque ratios than any other disc coupling. The availability of flange

mounting systems ensures the right fit for your engine test bench. Our experience includes standard

engines as well as test benches for major motor manufacturers in support of Formula 1

racing.

Here is a list of Rexnord products at work in automotive engine test benches today:

A critical link between motor and machine in a power

transmission solution is the coupling, and Rexnord

understands that perfectly. We have a history of innovation

that dates back to 1919, and is built on an installed base

across countless industries with worldwide reach. The

broad array of Rexnord Coupling designs enables a deep

knowledge of end user needs that makes us keenly in tune

with application details.
