Hydraulic

Optional in-port flow
control is a meter-in
device with reverse
free flow check valve

U.S. Patent No. 8,444,128

• TuffGrip™ is currently available in a 2750 lb and 5500 capacity at 5,000 psi.
• Innovative design featuring a spring advanced work support within a double acting shuttle cylinder.
• TuffGrip™ sleeve design is 2.5 times thicker than other work support models on the market. This sleeve efficiently closes and uniformly grips the plunger making it superior in precision applications.
• After the shuttle has retracted and the plunger is released to its spring advanced state, the plunger will clear the part by a minimum of 0.125 inches, eliminating the ejection of the work piece.
• Top flange body style allows for hydraulic connection through face sealed o-rings or through SAE ports.
• Sealed design and dual wipers keep chips and debris out so unit operates smoothly.
• BHC™ (Black Hard Coating) body, hard chrome plated shuttle piston and stainless steel plunger promote long life in harsh machining environments.
• Optional In-Port Flow Control is a meter-in device witth reverse free flow check valve.

• Optional In-Port Sequence valve is a sequencing device with reverse free flow check valve.

  
   

For proper sealing, mating surface must be flat within 0.003 with a maximum
63 µin R_a surface finish. 

All dimensions are in inches.

* Plunger stroke "B" is the available work zone of the plunger. The work piece must be positioned inside this window to prevent part ejection.

** Shuttle Stroke "C" is the stroke the shuttle travels to position the work support plunger relative to the work piece.

*** The difference between "C" and "B" (C-B) equals the minimum distance the plunger is below the work piece in the retracted position.
