Cat® Coupler Cam is a device that is used to engage and disengage the lock in quick coupler attachment. It is a vital component to hold the coupler in place. Cat® manufactures high-quality cams for various types of applications. They are made of ductile iron casting, which are durable, resistant to corrosion and wear. They have roller or needle bearings at the contact points, which reduce friction, noise, and heat generation. Caterpillar design engineers match the right combination of dimensions, materials, surface finish, and manufacturing processes, to each part to enable them to work and wear effectively with all the other neighboring and dependent parts. Cat® Rocker arms are tested and certified to meet the highest standards of quality and reliability.Application:Cat® Coupler Cams are used in Quick Coupler Attachments of Cat® Machines.
