Workholders - Hydra-Grip Arbors and Chucks
Figures (1) and (2) illustrate typical split sleeve adapters. Where expansion is required beyond the range of solid steel sleeves, use of split sleeve adapters may be recommended.

Figure (3) illustrates how chucking diameter (A) may be extended by adaption of a split sleeve, to chuck part having (X)chucking diameter. The tolerance on (X)diameter must in this case be equal to, or less than part tolerance on (A) diameter.

Figure (4) illustrates the use of a separate split sleeve adapter where restricting factors make it otherwise impossible to chuck in two bores.
