Carr Lane CLR-1942-510 | 28.00mm Diameter x 10.00mm Stroke Threaded Body Work Support - Fluid Advanced

Product Information

7250 psi max Double Acting Fluid Advanced 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. In the double-acting type shown here, the return stroke of the support plunger is effected in a precisely defined time, which is advantageous in timing-dependent automated installations. These threaded-body work supports are amazingly compact. Manifold mounting capability allows space-saving low-height installation. Highly corrosion resistant with stainless steel plunger and internal components. Metallic wiper and FKM wiper together provide excellent protection against dirt and coolant entry. Hardened contact bolt furnished. Available in four sizes, with the following load capacities at 7250 psi:          1460 Lbs          3400 Lbs          5300 Lbs          9400 Lbs

Application Information

A specially designed metallic wiper edge effectively protects the FKM plunger wiper from hot, abrasive chips.

Support Action (Fluid Advanced, Double Acting)

Plunger is normally retracted for clear workpiece loading and unloading. Applying fluid pressure to the lower passage 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 switched to the upper passage. 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.

Optional Pneumatic Contact Control

Design Considerations

Supporting Underneath a Clamp If the workpiece is light enough that plunger contact could lift it, use a Sequence Valve to delay advancing the work support until after the workpiece is clamped. Do not use the plunger to lift loads, or support side loads. The support plunger must always be protected against penetration of contaminants by a contact bolt (furnished).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.
