7 MPa Work Supports
Spring Advance Top Flange Work Support
Support Most Parts n Available in four capacities: 5.5 kN, 10 kN, 16 kN and 26 kN. n When using the 3-2-1 locating principles, you often need additional support for a 4th, 5th or even more areas on your part. A work support gives you “floating” locators that won’t interfere with your 3, 2 or 1 location. Clamp over your locators then lock the supports. n Spring extended plungers maintain contact with the part during loading, exerting only spring force against the part. When hydraulic pressure is applied the plunger “freezes’ without exerting any additional force on the part. n If spring advance supports are used in flood coolant environments, vent to clean dry air. n Top Flange minimizes the distance from mounting surface to the part for compact and efficient fixture design. n Choose between a High-Tension or Low-Tension spring to fit your application. n Plumb through BSPP ports or manifold mount top flange work supports. Bearing grade stainless steel plunger and collet assembly helps guard against corrosion in most machining environments. Proprietary wiper and seal designs reduce contamination and drag for longer lasting, better performing work supports.

Oil Capacity (cm 3 )
Spring Advance Work Supports; spring lifts plunger, part weight depresses plunger, hydraulic pressure locks in place. WARNING: Operating above 7 MPa may damage the work support and will void warranty. * Support capacities are listed at 7 MPa (70 bar) maximum pressure. Support capacities for other pressures are shown on the Capacity Charts at the start of Section B. ** "P" in the formula is hydraulic pressure measured in MPa. *** To allow for work piece height variations, it is recommended that the plunger contacts the part at Mid-Stroke.
NOTE: Work Support Capacity to be equal to or greater than 1.5 times clamping force plus machining force.
