<p>A collet chuck has separable jaws (16) which are freely slidable in a housing (11) and which have outer and inner taper faces (21, 33), the outer faces (21) being engageable by a complementary face (14) on a sleeve (13) which is axially movable to urge the jaws (16) radially inwardly. An inner sleeve (30) and a spacer (31) can be fitted in addition, to move the jaws (16) axially to cause them to be urged radially outwardly by a taper face (32) on the inner sleever (30). The jaws (16) are located on a rigid ring (19) and retained in position during assembly by an elastomeric ring (20).</p> |
