COR-LOK® Core Adapters

CAC® COR-LOK® core adapters are the perfect answer for running larger cores than your current set-up can handle. These sleeve-based core adapters are effective with all air shafts and thru shafts. Set screw to split bushing locking ensures easy, fast and secure locking to your existing air shaft. The split bushing design will not mar or damage your air shafts. No modifications to your existing set-ups are required. Change-over for different size cores can complete in less than 10 minutes with CAC's slide-on design.

CAC's Lightweight Thru Shaft

Lighten your load with our lightweight thru shaft. CAC's thru shaft is manufactured from hallowed tubular steel and offers a light weight solution with a lot of beam strength for heavy rolls of material. It is a very attractive way to provide a much lighter core support solution. Beam strength primarily is from the outside diameter, the small amount of stiffness lost with the hallowed design is well worth the benefits. We offer solid steel ends to fit your needs.

Couple our lightweight thru shaft with our core support products to achieve a complete solution. Customize your solution by using our end plug and air shaft, or ShaftLok™ safety chucks. Increase productivity and reduce employee injury with this effective, low cost option.
