Expanding chucks
Chucks
Model 714/MZ pneumatic-mechanical expanding chuck
Primarily recommended for unwinding where perfect centering is needed, it can also be used for winding and re-winding. Dependent on core size, a 20 mm expansion range is available. This chuck carries more weight at faster speed and transmits more torque than any other chuck available. Light-weight adaptors for additional core sizes can be supplied. Can be expanded using air valve or rotary union.
Model 711/MA mechanical self-expanding chuck
The 711/MA is recommended primarily for unwinding of both steel and cardboard cores. Concentric running and expansion is by means of a cam.
Model 713 MA Mechanical self-expanding chuck with sector
Model 714/MZ-A pneumatic-mechanical self-expanding chuck
The body and expanders are available in steel only. Based on the 714/MZ chuck, the MZA has a self-expanding system to give even great torque transmission and grip.
Model 714/AD mechanical expanding with axial thrust
The body and expanders (leafs or lugs) of the 714/AD are available in steel or rubber covered.
Model 718/PH
Designed primarily for lifting and vertical handling of reels, the 718/PH provides safe core gripping during lifting and transporting operations. The chuck body and the expanders (lugs or leafs, depending on the application) are available in steel only.
Model 715/PG air chuck
Recommended for unwinding and rewinding with cores. The body of the chuck can be either light alloy or steel, whereas the expanding section is made of a high resistance rubber tyre. When deflated the tyre is concave in design so it retracts below the diameter of the end plates. This results in quicker reel changes as there is no rubber in contact with the core as with competitor chucks.
Model 740/PL air chuck
The chuck body is available in steel or aluminium, and the expanders in steel, rubber, plastic or in combination, depending on the application. This chuck is manufactured to suit individual applications so overall diameter, bore size and length are all made to order. When the need is for a lightweight, concentric chuck to fit on an existing air shaft or passing bar the 740/PL is the answer.
Model 716/PK air chuck
Designed for unwinding and rewinding with cores, the body of the chuck is normally made of steel and the expanders (lugs) come in either hardened steel, aluminum or
rubber-covered depending upon core material and torque requirements.
Safety chucks
Foot or flange mount normally sold in pairs, one chuck shafted for the brake of the drive mount and the other plain ended. Finger guards are fitted as standard.
Model 900K
Competitive safety chuck with finger guards and foot or flange mount for shafts with square ends.
Model 910
Diamond shaped jaw and designed for faster speeds.
Model 925
A high-speed chuck manufactured with round or square jaws to eliminate end-float and shaft chatter so journal and jaw wear is at a minimum.
Model 950
As the 925 series but with facility of side lay adjustment to assist with reels that have slack or baggy edges.
