Important to Regulate for Safety! Maximum Recommended Input Pressure WARNING: SAFE INPUT PRESSURE SHOULD BE REGULATED FOR THE COLLET, NOT THE CAPABILITY OF THE COLLET BLOCK. DO NOT EXCEED THE RECOMMENDED INPUT PRESSURE LISTED BELOW—DAMAGE TO THE COLLET WILL OCCUR AND BODILY HARM MAY RESULT FROM THE COLLET COMING LOOSE. DRAW FORCE RATIO x INPUT PRESSURE = DRAW FORCE OUTPUT (not to exceed max collet safety output force) x COLLET GRIP FORCE RATIO = THEORETICAL COLLET GRIP FORCE COLLET BLOCK PART NUMBER 7799-00-00-420010 7799-00-00-650010 7799-00-00-000088 CB-0007901-A 7799-00-00-000095 7799-00-00-000094...

FlexC™ Dead-Length Collet Blocks High-Pressure 42 and 65mm Hydraulic USES COLLETS TOP VIEW C D, 4x C BACK VIEW 1/4 NPT Supply Ports, 2x FlexC Collet Blocks are ideal for either horizontal or vertical machining center applications. Their low profile provides maximum tool clearance with the ability to machine taller workpieces. With a maximum working pressure of 2,000 PSI and a draw tube force of 11.3 (42) and 14.1 (65) times the applied pressure, these units provide superior part rigidity with no pushback or rotation during heavy machining. Double-acting, dead-length operation assures maintained...

Dead-Length Collet Blocks 1C, 3C, 5C and 16C Pneumatic or Hydraulic USES COLLETS Dead-length design assures part length consistency from part-to-part. This family of collet blocks can be used on pneumatic service of 250 PSI (150/5C), or hydraulic service of 750 PSI (2000/16C). The collet blocks are machined from aircraft quality aluminum for long life. Forces generated by the draw tube range from .73 (1C) to 7.5 (5C) times the line pressure applied. Combine units for multiple part setups. Connector bushings (page 14 or 17) will eliminate the external plumbing between units. Patented collet locking...
