Four-jaw manual wedge bar self-centering chucks PR4-500.180New

Description

The chucks are designed for mounting on universal and special lathes. The design of the chucks provides high pressure force transfer with much less vise grip wrench torque compared to concentric jaw chucks. Wedge bar chucks have high wear resistance and long service life, stability in reaching high precision of centering parts. The basic package includes a set of hardened reversing jaws that perform the function of direct and reversible jaws when reinstalling. Under the customer request chucks are packaged with additional set of non-hardened (soft) jaws and intermediate jaws for specific setups with them.
