Block Clamps are ideal for pressing and assembly operations. In this example, a small press is made using a Block Cylinder and Hand Pump.

7500 psi max
Single and Double Acting
FEATURES: Compact design with many applications. Easy to mount on flat surfaces, horizontally or vertically. Excellent for punching, pressing, and assembly operations, with very high forces available. Double-acting version can also be used for pulling, by reversing the A and B ports.
SIZES: Available in nine sizes, USA or metric plunger threads, with a choice of stroke lengths up to 100mm — see Dimensions page for part numbers. Larger sizes and longer stroke lengths available by special order. Push force at 7500 psi:| | 2300 Lbs | | | 5700 Lbs | | | 9300 Lbs | | | 15000 Lbs | | | 23000 Lbs | | | 36000 Lbs | | | 59000 Lbs | | | 91000 Lbs | | | 140000 Lbs |
CLAMPING ACTION: Applying fluid pressure to the A port advances the plunger. Spring return (single acting) or fluid return (double acting).
MOUNTING: Several possible mounting methods: 1) insert four socket-head cap screws from the plunger end, through the four counterbored holes parallel to the plunger; 2) insert four socket-head cap screws from the bottom end, through the four counterbored holes parallel to the plunger; 3) insert two socket-head cap screws through the two broad-side holes perpendicular to the plunger. Method 3 requires that the Block Cylinder be backed up for pressures over 2300 psi by a rectangular strip or dowel pins with a height at least 1/3 of the B dimension.
FLUID CONNECTION: 1/4" BSPP port (two for double-acting clamps). Larger sizes have 1/2" BSPP ports. Do not use NPT fittings.
OPTIONAL VITON SEALS: For high-temperature applications (212° to 300° F), we offer Viton seals in all sizes. Please contact factory for more information.
CONSTRUCTION: Plunger > Steel, case hardened. Body > Steel, black oxide finish. |
