Ace Ratchet Collar Force

Based on the well-known Ace Ratchet Collar, the updated and patented 2-piece collar uses a proprietary ratchet mechanism, press fitting the two sets of ratchets together to permanently lock the collar to the casing.


The ARC-Force is small in size but big on strength, with a holding force of 50,000 lbs. It includes zero loose or moving parts and has no impact on drift, while its availability for quick delivery means no long wait to impact production costs.

While Ace’s ARC-Slim is made for close tolerance applications, the ARC-Force is a cost-effective solution for non-close tolerance operations and is based on patented and field proven technology.

Its size at 7 mm allows it to fit into most applications worldwide. It is manufactured from 4140 steel or chrome materials, with non-standard materials available on request.
