Live Chuck Applications

Riten Live Chuck Mandrels are designed specifically for applications where the ability to chuck both ends of the part is essential.  The live chuck mandrel combines the rotational ability of a live center with the flexibility of a jaw chuck.  Rolls with damaged centers can be chucked and indicated with a 4-Jaw chuck.  Alternatively, you can chuck a dead center, center the part and offset the shaft with a 4-Jaw chuck.

Other chucks can be mounted as well.  Riten works with several chuck manufacturers as well as mounting chucks supplied by the customer.
