Kmt Litzer Type Safety Chuck
The kmt safety chucks are engineered to easily fit the same bolt patterns of the obsolete Super Chuck A and B-series with no additional modifications or adapter plates. Converting to a Double E safety chuck is simple and with the sliding style faceplate is safer and more reliable
Safety Chucks Do Three Things
- Exact bolt patterns and mounting dimensions as the old Super Chucks
- No frame or shaft modifications needed
- Sliding style faceplate
- Internal cam prevents chuck from opening unless upright
- External sliding faceplate
- Available in both foot and flange mount
- V or U shaped inserts to any size of existing Super Chucks
They provide for quick change at the end of a production run (either winding or unwinding). Less down time during turn around, the more cost efficient is your operation.
They provide a means of transmitting torque to the roll you are winding unwinding, Torque in the form of a drive on the rewind end of the operation and torque from a brake on the unwind side. i
And finally. Safety Chucks provide for concentricity between the centerline, or axis, of the Safety Chuck and the center line of the roll shalt. Less eccentricity between the roll shaft and Safety Chuck means less vibration and wear.What Is A Safety Chuck?
It is a quick coupling used in shafted center wind and center unwind applications.
A safety chuck is a specialized quick coupling used for web handling operations. in order to maintain the desired tension in a web, a shaft from which a roll is being unwound must be subject to a constant level of torque from a tension brake. Similarly. a shaft onto which a roll is being wound must be subject to a constant level of torque from a motor via a slip j tension v clutch. A safety chuck provides a means to transmit torque to a rail shaft as well as the ability to switch roll shafts quickly and conveniently. Unlike most couplings, a safety chuck does not require loosening and tightening of screws or moving any component other than the shaft and the chuck itself. Tension brakes, clutches, and motors need not be moved or dismounted.
