Threaded-Body Work Supports

spring extended or fluid/air advanced

Features

  • manifold mounting capability allows space-saving low-height installation.
  • available in the four versions Spring Extended, Fluid Advanced, Air Advanced, Fluid Advanced, Double Acting
  • adjust to the proper height for supporting a workpiece, then lock securely to become fixed rests
  • provide extra loading clearance and are ideal for workpieces that are too light to depress a spring-loaded plunger.

Threaded-Body Work Supports are amazingly compact. Manifold mounting capability allows space-saving low-height installation. Available in the four versions shown below:

      • Spring Extended
      • Fluid Advanced
      • Air Advanced
      • Fluid Advanced, Double Acting
Work Supports automatically adjust to the proper height for supporting a workpiece, then lock securely to become fixed rests. Fluid-advanced Work Supports provide extra loading clearance and are ideal for workpieces that are too light to depress a spring-loaded plunger. Air-advanced Work Supports allow fine-tuning contact force using a Fine Air Pressure Regulator, and provide separate control of plunger advance. The mini threaded-body version shown here is amazingly compact. Manifold mounting capability allows space-saving low-height installation. Hardened contact bolt furnished.
Available in two sizes, inch or metric, standard or long stroke, with the following load capacities at 7250 psi:
          1460 lbs (Inch – Standard Stroke)
          1460 lbs (Metric – Standard & Long Stroke)
          2100 lbs (Metric – Standard & Long Stroke)
Support Action – Air Advanced 

Plunger is normally retracted for clear workpiece loading and unloading. Applying air pressure gently advances the plunger to the workpiece, where it contacts with light force. A Fine Air-Pressure Regulator, Air Extractor Dryer, and Air Clamping Valve are required for air control (see Related Products below). Fine-tune contact force using the air regulator. When fluid pressure is applied, the precision sleeve grips the plunger, locking it securely. The plunger retracts again when fluid pressure and air pressure are released. These Work Supports can also be used as “Air Extended” supports by leaving air pressure constantly on.

Locking height is repeatable within +/-.0002″. Such excellent repeatability is possible because of two design features: 1) a precision sliding-fit pressure sleeve holds the plunger absolutely vertical even while unlocked, avoiding any inaccuracy due to locking a tilted plunger, and 2) locking force is entirely radial, so the plunger remains absolutely stationary during the locking process.
Support Action – Spring Extended 
Plunger is normally extended by light spring force. When the workpiece is loaded, its weight depresses the plunger to the proper height. When fluid pressure is applied, the precision sleeve grips the plunger, locking it securely.

Support Action – Fluid Advanced 
Plunger is normally retracted for clear workpiece loading and unloading. Applying fluid pressure gently advances the plunger to the workpiece, where it contacts with light spring force. As fluid pressure increases, the precision sleeve grips the plunger, locking it securely. The plunger retracts again when pressure is released. Locking height is repeatable within +/-.0002″. Such excellent repeatability is possible because of two design features: 1) a precision sliding-fit pressure sleeve holds the plunger absolutely vertical even while unlocked, avoiding any inaccuracy due to locking a tilted plunger, and 2) locking force is entirely radial, so the plunger remains absolutely stationary during the locking process.

In this example, the workpiece is supported by three fixed rest buttons and three self-adjusting Work Supports. Supports and Edge Clamps are all manifold mounted, so the fixture has no exposed fluid lines to trap chips.

The optional mounting base adds 10mm to the Work Support’s overall height.
