AP-RC AP-RD
Quick jaw change high precision power chuck Ø 170 - 400 mm ■ Closed center ■ 3 jaws ■ proofline ® chucks = fully sealed – low maintenance Application/customer benefits • For mid to large batch flexible production • Quick jaw change = short set up time • Fully sealed, ideal for dry machining of castings and forgings or if high pressure coolant is used • Ideal for vertical, pick up and horizontal machines AP-RC: Quick jaw change with TONGUE & GROOVE master jaws AP-RD: Quick jaw change with SERRATED master jaws (2.5 mm x 60°) (radially adjustable) Technical features
Quick jaw change TONGUE & GROOVE
Quick jaw change SERRATION

Safety advice / danger of damage: When using taller / heavier jaws and / or clamping on a bigger diameter reduce draw pull / rotating speed accordingly.
The data in the diagrams refer to 3-jaw chucks, newly maintained according to their service manuals using SMW-AUTOBLOK K67 grease.The static and dynamic gripping forces have been measured using standard soft top jaws, placed in a position not exceeding the outer diameter of the chuck.
