Unique Air Shaft for Unwinding and Rewinding
COR-LOK air shafts are different. Their unique design provides high-torque core locking with zero core damage. COR-LOK B2 series air shafts utilize inflating tube engineered to fit the COR-LOK spiral internal housing. Inflating the air shafts with pressurized air will actuate COR-LOK's interlocking segments to engage the core and lock it in place. These interlocking segments expand evenly around the circumference and across the width of the core, ensuring even torque distribution in the core's inside diameter. This means your cores will not slip and will not distort during the unwind / rewind process. Standard air shafts are supplied with thru bores, regardless of length. They may be mounted to any thru bar / shaft; locked in place with CAC's unique split bushing design. Custom designs are available with thru shafts or mounted journals. Standard air shafts may be used in cantilevered and dual support applications.

Features: Lightweight - easy to use Interlocking segment design is easy to slide in and out of cores for fast roll changes High torque output to ensure your cores stay locked - no core slipping Interlocking segment design ensures zero core damage Engineered inflating tube (bladderless) Built to last 15 Minute maintenance 1" to 18" Diameter cores 3" - 120" Roll or core widths Aluminum (standard), steel, stainless steel and carbon fiber construction Thru bore design (standard) Standard designs Custom designs to fit your machine Combine with CAC's unwind and rewind modules for a complete engineered solution Made in the USA

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.
