When do I need a water-cooled brake instead of an air-cooled brake?
When the brake has to absorb high horsepower continuously: dynamic tensioning, sustained slip or repeated heavy stops. Water cooling carries the heat away so the brake can run at loads that would overheat an air-cooled design.
What do the size codes mean?
The code reads as number of discs, disc diameter, type and generation. For example, 236WCB2 is a two-disc brake with 36 in. diameter discs: WCB means water-cooled brake, and the 2 means second generation with a single air piston. A D, as in 236WCBD, means a dual air piston. Send us the nameplate if you are unsure.
How do I find parts for my brake?
Use the size from the nameplate or part number. The size tables below link to every listed part: friction kits, pistons, reaction and pressure plates, gears, studs and seals.
Do you rebuild water-cooled brakes?
Yes. We rebuild Airflex water-cooled brakes and supply genuine friction kits, wear plates and seals.
Is Eaton Airflex the same as Vickers or Danfoss Airflex?
Yes. Airflex was an Eaton brand for decades. Danfoss acquired Eaton's hydraulics business in 2021, and Airflex is now part of Vickers by Danfoss, alongside Vickers hydraulics. It is the same product line, from the same engineering team, with the same part numbers, so we supply genuine parts and rebuilds whether your unit says Eaton, Danfoss or Vickers.
