Collets and bushings from smaller capacity machines may be used in larger capacity machines by changing the adapter sleeves.

To insure getting the correct parts, check the inside diameter of the sleeve you are using and compare it to the bearing diameter (D) of the collet and bushing listed on the next page.

* Refer to separate section in this catalog for MPC attachment collets.

NOTE:
Generally, guide bushings are used in stationary or revolving guide bushing holders. For profile material, revolving bushings are essential. However, in special cases where round stock is turned in revolving bushings and extreme concentricity between the stock and the turned diameters is required, extra precision (XP) bushings are available. These bushings command higher prices, longer deliveries, and should only be specified when the requirements justify their use.

NOTE:
Meehanite is compatible with most materials, including those which have a high tendency to “pick up”. However, meehanite has a wear life that is considerably shorter than that of carbide. Meehanite is supplied in round bore sizes only.

* When ordering please add a suffix of “ST” for steel bushing or “M” for meehanite bushing.
