Universal Ball-Lok Power Chuck
N.A. Woodworth’s comprehensive line of workholding begins with the “UBL”. It is “The Original” used industry wide and it sets the standard for all other power chucks.
The UBL features a positive pullback action chuck and the chuck is internally lubricated with a sealed design to keep out chips and other contaminants. The jaw homing feature allows jaws to compensate for variations in the part, and jaws for different workpieces can be easily exchanged.
The Universal Ball-Lok power chuck offers an optional on/off feature which allows an easy change from centralizing to compensating, and there is also an option of a higher top plate design to swallow long workpieces.
