Roemheld Block Pull Cylinders
7250 psi maxSingle Acting
Pull-clamp version of the popular Block Cylinders. Plunger is extended with pressure off, then retracts when pressure is applied. Compact design with many applications. Easy to mount on flat surfaces, horizontally or vertically. Excellent for pressing and assembly operations, with very high forces.
Clamping Action
Applying fluid pressure retracts the plunger. Spring return to extended position.
Mounting & Fluid Supply
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. 1/4" BSPP port. Do not use NPT fittings.
Optional Vital Seals
For high-temperature applications (212° to 300° F), with Viton seals. Viton seals have a slightly shorter service life.
