Power Transmission FAQs

We publish a grease schedule based on duty cycle. Contact your Regional Sales Manager if you'd like a copy.

The differentiation is related to the rotation of the drives, as you can see from the diagram below (with left first and right second). 

3-5 degrees

Discs and brakes are normally not sold as matched units. Although the disc thickness must be matched with a brake, the diameter and thickness of the disc depends on each specific application.

The disc must be sized to perform at least 2 functions; assist the brake in producing torque and to dissipate heat. To calculate torque requirements and heat generation refer to the selection guidelines in our brake catalog.

The answer lies in a process called burnishing, the "running in" of an applied brake for a specified period of time. This conditions the disc (rotor) and ensures a proper mating surface between the two components. A static application would assume this process has not yet occurred and therefore the surfaces are not properly conditioned.

No. Brakes are manufactured fluid specific. Seals compatible with brake fluid are not compatible with hydraulic oil and vice versa.

There are many different types of lining materials featuring varying degrees of wear characteristics and coefficient of friction. Our linings are made primarily from organic materials with no asbestos or lead fillers.
