Lever Actuated Shaft Collars
Stafford Staff-Lok components allow collars to be moved without tools.
Stafford Manufacturing Corp. has expanded its Staff-Lok line of lever actuated shaft collars, which can be opened, moved, and re-clamped by hand for use in larger, non-rotary applications. The collars feature an integral hinge with a conformal cam lever for clamping and a knurled nut for adjusting the clamping preset, which makes it easy to move by lifting the lever, moving the collar, and clamping it by hand.
Machined from steel with a smooth bore, Staff-Lok Shaft Collars come in three body and round bore size combinations: 2-1/8 inches O.D. with 1/2-, 5/8-, 3/4-, 7/8-, and 1-inch bores; 3-1/4 inches O.D. with 1-1/8-, 1-1/4-, 1-1/2-, and 1-3/4-inch bores; and 4-1/4 inches O.D. with 2-, 2-1/4-, and 2-1/2-inch bores.
