Air-advanced Work Supports have a plunger that is normally retracted for clear loading. Applying air pressure gently advances the plunger to the workpiece with light, adjustable force. Applying fluid pressure locks the plunger securely.

BESONDERHEITEN: Work Supports automatically adjust to the proper height for supporting a work piece, then lock securely to become fixed rests. Support plunger is held by a precision sliding-fit pressure sleeve that provides incredible accuracy and repeatability. Air-advanced Work Supports allow fine-tuning contact force using a Fine Air Pressure Regulator, and provide separate control of plunger advance. The top-flange version shown here allows space-saving low-height installation using either standard fittings or manifold mounting. These supports have high load capacities yet are extremely compact and easy to install. Dual mounting capability allows installing with either standard fittings on the back side or manifold mounting from below. Highly corrosion resistant with stainless steel plunger and internal components. Standard metallic wiper provides excellent protection against dirt and coolant entry.
GRÖßEN: Available in three sizes – see Dimensions page for part numbers. Load capacity at 7500 psi:| | 3900 Lbs | | | 9800 Lbs | | | 24000 Lbs |
ABSTÜTZFUNKTION: Plunger is normally retracted for clear work piece loading and unloading. Applying air pressure gently advances the plunger to the work piece, where it contacts with light force (a Fine Air Pressure Regulator, Air Extractor Dryer, and Air Clamping Valve are required for air control). 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.
GENAUIGKEIT: Height repeatability within +/-.0002". Such excellent repeatability is possible because of two design features: 1) the 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. Elastic deflection of the plunger per 100 lbs machining load for the three sizes is only .00012", .00007", and .00003" respectively.
DESIGN-HINWEISE: The support plunger must always be protected against penetration of contaminants by a contact bolt (with an O-ring seal underneath the head), either the one furnished or a custom contact bolt. When supporting underneath a clamp, use a Sequence Valve to delay clamping until the Work Support has reached sufficient load capacity to resist the clamping force. Support load capacity should be at least 2 times clamping force at all times, to resist not only static clamping force, but also dynamic forces due to clamping-arm momentum and machining forces.
MONTAGE: Fasten support with three socket-head cap screws. For manifold mounting, the mounting surface must be ground flat to ensure proper O-ring sealing.
HYDRAULIK-ANSCHLUSS: Two 1/4" BSPP ports, one for hydraulic pressure and one for air pressure. For optional manifold mounting, use the O-ring ports underneath instead of the standard ports. Unscrew the sealing plug in each O-ring port and install a CLR-3000-347-SW O-ring (also install a CLR-810-F Port Plug in each 1/4" BSPP port). Do not use NPT fittings.
