Frequently Asked Questions

Which caliper do I need for an emergency or parking brake?

A failsafe, spring-applied caliper such as the Airflex ACB-F3 or a spring-applied Coremo caliper, which holds when pressure is lost. Active (pressure-applied) calipers such as the DPA suit service and tensioning stops.

Do you supply Coremo pads and linings?

Yes. We supply Coremo calipers, pads, linings and service parts. Search the parts finder or send us the caliper model and pad size.

Where are Airflex calipers used?

Mining conveyors, grinding mills and hoists; oil and gas drawworks, top drives and rig cranes; and marine deck machinery, metals, wire and cable.

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.
