Eaton-Airflex WCSB brakes are typically used in:

  • Draw works
  • Mooring systems
  • Log yarders


Airflex WCSB elements are air-applied, water- and air-cooled, multiple-disc brakes designed for heavy-duty brake/tensioning applications. They are similar to the WCB line except for a feature that allows for greater control of the braking/tensioning function.

The WCB element features dynamic tensioning, static holding, and emergency stopping, which are provided by one brake, removing the need for multiple braking systems. It also features a specially formulated friction material interfacing with a copper alloy surface, which eliminates the stick-slip characteristics associated with ordinary frictional devices.
