Roemheld CLR-1853-T090-L16 | 3 Series Size x 90 ccw Direction x 8mm Stroke Double Acting Swing Clamp – All Industrial Tool Supply

Description

Roemheld Swing Clamps for Low-Pressure Hydraulic Systems

1000 psi max

Double Acting

This unique series of Swing Clamps provides considerable clamping force at lower hydraulic pressures, allowing direct connection to the low-pressure hydraulic system of a machine tool. These are extremely compact, heavy-duty clamps with a reinforced swing mechanism and a heavier clamping arm to exert high clamping force in relation to clamp size.Swing Clamps utilize a sturdy helical-cam mechanism to swing the clamping arm clear for unrestricted loading. Arm can be mounted to start its 90 swing from any position within 360. The top-flange version shown here allows low-profile mounting, using either standard fittings or manifold mounting.Available in four clamp sizes, double acting only, with a choice of clockwise, counterclockwise, or 0 swing.

Application Information

Clamping Action

Swing Clamps are pull-type cylinders where part of the total stroke is used to swing the piston, and the remaining stroke is available as the clamping range. Applying fluid pressure to the A (clamping) port swings arm 90 over workpiece then clamps down. Switching pressure to the B (unclamping) port positively lifts arm then swings it back 90 for loading/unloading.

Reinforced Swing Mechanism

Reinforced swing mechanism ensures positive arm position. The safety-clutch mechanism normally incorporated into the swing clamps is omitted in this design. In case the workpiece hits the clamping arm during loading, the angular position of the swing-clamp arm will be exactly maintained. Using a longer, heavier clamping arm will also not declutch the swing arm and affect arm position.

Mounting Fuid Supply

Fasten clamp with four socket-head cap screws. Dual mounting capability provides every clamp with the option of using either standard fittings or manifold mounting. Two 1/4″ BSPP ports. Do not use NPT fittings.

For optional manifold mounting, use the O-ring ports underneath, instead of the standard ports. For manifold mounting, the mounting surface must be ground flat to ensure proper O-ring sealing.

Standard Fittings

Manifold Mounting

Clamping Arm

Maximum allowable operating pressure is 1000 psi. Longer, custom clamping arms will reduce allowable operating pressure, inversely proportional to arm length.
