Core chucks are available in sizes 4", 5", 6", as part of the standard manufacturing program. The 3" is only available as a mechanical chuck since in most cases a 3" dia airshaft is better and more economical.

Chuck, for 6" cores, is the most popular chuck in our manufacturing program. It was designed with the help of some of our customers, safety being the main factor. Has an internal bladder protected by aluminum leaves, which protect the air bladder from being cut, and also limit the expansion of the chuck so it won’t "blow-out" if inflated outside of a core. The gripping element is a tough rubber compound that will grip all types of cores. It is easily and economically replaced when worn. The LR6 chuck is available with adapters for many bore sizes, and is usually stocked in 2.950" bore for standard AIR SHAFTS. It is available with a double split collar clamp, a single split clamp, and a set screw lock. "Tie Tube” option is available when multiple chucks are used in a single core. This allows numerous chucks to be inflated and deflated from the end chucks.

Normally chuck bores are supplied to a tolerance of plus .010" of the shaft size. This is in order for the chuck to run as true as possible and still be easily slid on or off a shaft. Closer tolerances are available when required. Adaptors are available for square shafts and small diameter shafts.

When ordering chucks for air shafts it is recommended that the shaft be checked for size, since shafts can be supplied with non common diameters.

NOTE: Air Chucks are the same as Air Shafts. They must be inflated to the correct air pressure to perform properly, use with low air pressure will cause the roll to slip and wear out the chuck. The recommended air pressure in the chuck is 85-90 psi or approx. 6 Bar. Use with lower pressure will void the waranty.
