PTF
High precision 4-jaw independent manual chuck Ø 530 - 2000 mm
■ Closed center ■ 4 jaws (all diameters)
TONGUE & GROOVE Manual clamping and radial setting of jaws
Application/customer benefits • Clamping of large round, square and irregular parts • Manual, radial setting of component and manual clamping • Suitable for vertical machines. Strong body and master jaws design and option to easily mount a strong center point • High gripping force allowed by the strong design, with the option to increase it with a torque multiplier • Tongue & groove master jaws (type “American Standard”) Technical features • Manual gripping force applied by a strong and protected screw on a strong and rigid master jaw • Manual and fine setting of master jaws for workpiece centering • Protection from contamination with seals along the master jaw profiles • Possibility to use jaw boxes for manual clamping mounted on the T-slots between the master jaws

Optional 5:1 torque multiplier To achieve the maximum gripping force and speed, the easiest and most comfortable way is to use this multiplier that will increase 5 times the input torque. Id. No. 13506320
Safety advice / danger of damage: When using taller / heavier jaws and / or clamping on a bigger diameter reduce operating torque / rotating speed accordingly.
