Block cylinders with internal piston rod thread are ideally suited for clamping situations where short travel with high forces is required. Block cylinders can be used as thrust or traction cylinders. Various thrust pieces can be screwed into the internal threads of the piston rods The block cylinders ensure a high operating pressure and are easy to fasten using cap screws due to their compact, cubic housing design. A double hydraulic seal is installed in the block cylinders as standard. This creates technical advantages for the rod-side seal for low-leakage continuous operation. Metal wipers are also installed in the block cylinders as standard to prevent the ingress of metal chips.

Housing and piston steel.
Seal NBR

Housing black oxidized.
Piston hardened.

Transverse forces on the block cylinders should be avoided.

If the block cylinder is mounted transversely to the cylinder axis, additional support for the block cylinder is recommended. If the block cylinder is used as a thrust cylinder, the support should be on the underside; if it is used as a traction cylinder, it should be on the rod side.
Permissible dynamic loads during the piston advance stroke must be observed.
A vent port is required for the single-acting block cylinders.

Penetration of cutting and cooling fluids into the cylinder must be prevented.

Thrust pieces are not supplied.
