Up to 6 Romheld 2 3/4"-16 7500 psi max Work Supports 1914-710 702
Each bid is for ONE support.
3 1/2" height
SUPPORT ACTION (FLUID ADVANCED): Plunger is normally retracted for clear workpiece loading/unloading. Applying fluid pressure gently advances plunger to workpiece, where it contacts with light spring force. When fluid pressure rises above 1500 psi, precision sleeve grips plunger, locking it securely. Plunger retracts again when pressure is released. ACCURACY: Height repeatability ±.0002 inches. Excellent repeatability because: (1) sliding-fit sleeve keeps plunger absolutely vertical while unlocked, avoiding inaccuracy due to locking a tilted plunger; and (2) locking force is entirely radial, so plunger stays absolutely stationary during locking. Elastic deflection of plunger is only .00007 inches per 100 Ibs. machining load.
Automatically adjusts to proper height for supporting workpiece. Prevents deflection and vibration due to machining forces. May also be used underneath clamps to back up clamping force. More accurate, more consistent, and much faster than screw jacks.
Precision sleeve around support plunger holds it absolutely vertical while unlocked, then locks it securely when fluid pressure is applied. Plunger remains perfectly stationary during locking. Far better accuracy and repeatability than earlier segmented-collet or sandwiched-plate work supports.
I will fully guarantee these items.
