Carr Lane CLR-1896-N90L-20DH | 20.00mm Stroke x 4000 lbs Clamping Force Standard Swing Clamp

Product Information

5000 psi max Double Acting Swing Clamps without axial swing stroke are designed especially for swinging into small side pockets to clamp. These compact, heavy-duty Swing Clamps have a reinforced swing mechanism. Clamping arm can be mounted to start its 90 Degree swing from any position within 360 Degree. The top-flange version shown here allows low-profile installation. Dual mounting capability provides every clamp with the option of using either standard fittings or manifold mounting. Available in three sizes, each with a choice of clockwise or counterclockwise swing, double acting only. Clamping force at 5000 psi with a standard clamping arm:          1100 Lbs     (3 series)          2700 Lbs     (5 series)          4000 Lbs     (6 series)

Clamping Action

Available with clockwise or counterclockwise swing Applying fluid pressure to the A (clamping) port swings arm 90 Degree over workpiece then clamps down. This clamp's swing is entirely in a horizontal plane. Switching pressure to the B (unclamping) port positively lifts arm then swings it back 90 Degree for loading/unloading.

Reinforced Swing Mechanism

Reinforced swing mechanism ensures positive arm position. The safety-clutch mechanism normally incorporated into our 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.

Optional Position Control

An accessory unit for pneumatic position control is available to monitor that the Swing Clamp is in "clamped" position. This simple, reliable unit consists of a stainless steel housing with a spring-loaded control tappet. To operate the tappet, a control bracket must be attached to the rear of the clamping arm. This bracket must be adjusted so that it first contacts the tappet during the downward clamping stroke, after the full swing stroke, at a height where it will not bottom out on the housing at full clamping stroke. When the clamping arm reaches "clamped" position, the pressure control is closed and the pressure built up at the pneumatic port can be evaluated with a differential pressure switch. Parallel connection of up to three controls is possible with a single differential switch.

Optional Metallic Wiper

This optional, additional wiper protects the FKM wiper against physical damage, e.g. by hot chips. These Swing Clamps are ready for mounting the metallic wiper, which consists of a radially floating wiping disk and a retaining disk which is pressed onto the existing collar. Clamps can be ordered with the metallic wiper already installed, or the metallic wiper can be ordered separately.

Mounting & Fluid Supply

Dual mounting capability allows any clamp to be mounted using standard fittings or manifold mounting. Two 1/4" BSPP ports. For optional manifold mounting, use the O-ring ports underneath, instead of the standard ports. Do not use NPT fittings. For manifold mounting, the mounting surface must be ground flat to ensure proper O-ring sealing. Fasten clamp with four socket-head cap screws.

Clamping Arm

Standard Clamping Arm 5000 psi max Gooseneck Clamping Arm 5000 psi max Order clamping arm separately below. Maximum allowable operating pressure is 5000 psi. Longer, custom clamping arms will reduce allowable operating pressure, inversely proportional to arm length. Optionally, the clamping arm can be positively keyed to the piston rod in a fixed 90 Degree position by inserting an indexing pin (order separately).
