Product Information

ROEMHELD Threaded-Body Work Supports – Air Advanced, B1.943 (1460, 3400, 5300, 9400 lbs) Part # CLR-1941-300P Carr Lane Mfg.®

7250 psi max

Single Acting

Air Advanced

Work Supports automatically adjust to the proper height for supporting a workpiece, then lock securely to become fixed rests. Air-advanced Work Supports allow fine-tuning contact force using a Fine Air Pressure Regulator, and provide separate control of plunger advance. The threaded-body version shown here is 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.

Data Sheet

Support Action (Air Advanced)

Diagram showcasing the application of Roemheld Threaded Body Work Supports Air Advanced B1943 1460 3400 5300 9400 Lbs

Plunger is normally retracted for clear workpiece loading and unloading. Applying air pressure gently advances the plunger to the workpiece, where it contacts with light force. A Fine Air-Pressure Regulator, Air Extractor Dryer, and Air Clamping Valve are required for air control (see Related Products below). 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.

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

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.

Mounting & Fluid Supply

Install Work Support directly into a flat-bottom tapped hole in the fixture – see drawing for hole-preparation instructions. Tighten to the recommended seating torque. Fluid passages must be drilled as shown in the drawings. Do not use NPT fittings.
