Spring Advance Work Supports - 4000 lb.

DE STA CO's Spring Advance Work Supports have a spring loaded plunger which contacts the workpiece as it is loaded into the fixture. The spring keeps the plunger in contact with the workpiece, allowing for variations between workpieces. To support any externally supplied loads the sleeve surrounding the plunger grips the plunger and holds it in place.

The 100884DE's threaded body may be compactly manifold mounted in your fixture or choose the 100885DE which includes the 100884DE work support and a mounting base for installation on a flat surface for conventionally plumbed circuits. Both feature fully corrosion resistant construction.

Extremely close manufacturing tolerances hold the plunger perpendicular to the workpiece and eliminates inaccuracies due to plunger movement during lock-up. After lock-up, the plunger is absolutely rigid and limits elastic deflection to .00004" per 100 lbs. of load. For base only, order number 5000028DE.

Features:

  • 4000 lbs. capacity @ 5,000 psi max.
  • Manifold or conventional base mounting
  • Full corrosion resistant construction
  • Small Filtered Breather/rest button to accommodate intricate workpieces
  • 1,000 psi minimum recommended pressure
