The body of the self-aligning pads is made from high quality steel (the group 02005 also has stainless steel bodies ). In this body sit either a hardened steel flattened ball or a ball made from POM, both of which can swivel up to 20°. They align automatically to the inclined faces of workpieces.
An exception is the self-righting group 02004, these do not have flattened balls. |
