Pneumatic Diaphragm Chuck Introduction

JATO JAP100 Cylinder-Integrated Pneumatic Diaphragm Chuck provides you with a high accuracy yet hassle-free diaphragm chucking solution, saving you from the trouble of installing rotary cylinders, tailor making any draw tubes or air feeders. And with its real front-mounting design, the installation is revolutionarily easier than ever.

With its super precision clamping accuracy (repeatability 0.005mm) and gentle clamping force, the self-contained JAP100 Air Diaphragm Chuck is your ideal choice for any accuracy-critical and fragile material machining tasks. Plus the highly sealed chuck body, it helps prevent cutting chips, dust or any debris from entering, further ensuring a longer product life of the chuck and its accuracy.

  • Repeatability is within 0.005mm.
  • Air cylinder is integrated: no rotary cylinder or draw tube is needed.
  • Real front-mounting design allows easy installation and operation.
  • Highly-sealed chuck body helps protect cutting chips, dust or coolant fluid from entering.
  • Gentle and precise clamping: suitable for fragile parts machining.
  • O.D. chucking / I.D. expanding chuck possible by changing jaw pads.
  • Oil-mist air lubricated. Very low temperature rising under high RPM.

Diaphragm Chuck Applications

  • Precision bushings.
  • DVD spindle motor assembly.
  • Bearing collars, bearing rings.
