Sherline 4-Jaw Self-centering Chucks

A four-jaw self-centering chuck is convenient for gripping round or square stock quickly. Shown on the left above is the 2.5" diameter chuck P/N 1075. On the right is the 3.1" diameter chuck P/N 1076. (Click on photo for larger image.)

2.5" and 3.1"Diameter 4-Jaw Self-centering Chucks...

These chucks combine the ease-of-use advantages of the 3-jaw chuck with some of the advantages of a 4-jaw chuck. They will automatically center square or round stock. (The stock must be accurately shaped for all four jaws to grip.) They will also grip thin-wall tubing in four places rather than three, which spreads out the load and allows more grip without crushing the tubing.

Turning the knurled portion of the outer diameter of the chuck scrolls all four jaws in unison. Included with the chuck are two Tommy bars for tightening and loosening the chuck.

Centering accuracy on self-centering chucks is to within a few thousandths of an inch. If perfect centering accuracy is required, see the page on 4-jaw chucks.

Jaw Tightness on Scrolling Chucks...

Sherline technicians custom grind each jaw to fit its own slot with as little play as possible. Grinding is done to within .0001". This assure maximum accuracy. If you have sent in an old chuck for jaw replacement or are replacing an old, worn chuck, you will notice that the new one is initially harder to turn than your worn one. As chucks wear, they become looser and easier to turn. Some users like a chuck that turns easily right from the start for quick part changes, where maximum accuracy is not as important as speed and ease of use. In your preference, Sherline makes and sets aside a certain number of chucks with less tightly fit jaws. If your job calls for repetitive, quick part changes and you can accept a little less centering accuracy, you may request one of these chucks at no extra charge. To do so you must place your order directly with Sherline by phone and ask for loose jaws, or if ordering from www.SherlineDirect.com, add a note in the "Comments/Shipping Preferences" box on the order for requesting "Loose Jaws on Chuck".
