Q: How much shaft load (weight) can a standard series Float-A-Shaft handle?

A:We recommend the use of a shaft supporting device (bearing) to prevent shaft loading directly on the Float-A-Shaft.

Q: How often do you need to lubricate the Float-A-Shaft?

A:We publish a grease schedule based on duty cycle.

Q: What is the amount of backlash expected from a Float-A-Shaft?

A:3-5 degrees

Q: How do I match a disc with a brake?

A: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.

Q: How do I select the proper disc?

A: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 pages 94-97 in our brake catalog.

Q: Why does the catalog list static holding torque as lower than dynamic torque? That seems backwards.

A: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.

Q: Can a "hydraulic oil" brake be used with a "brake fluid" model?

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

Q: From what material are the brake linings/pucks made?

A: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.

Q: What's the maximum operating temperature of the brake pucks?

A:Approximately 450 degrees Fahrenheit.
