OverviewSingle-acting hollow hydraulic cylinders deliver powerful force in a compact design, making them ideal for pushing, pulling, and tensioning applications. Featuring a hollow piston, they allow rods or cables to pass through, enabling precise operations such as bolt tensioning and bearing removal. These cylinders extend under hydraulic pressure and retract via an internal spring or an external load, ensuring efficient performance and reduced maintenance requirements.
Product summarySingle-acting hollow hydraulic cylinders are designed for high-force applications that require precision and versatility. Their hollow piston enables rods, cables, or bars to pass through the piston bore for tasks such as bolt tensioning, pulling, pushing and bearing removal. Constructed from high-strength alloy steel with corrosion-resistant coatings, they provide long service life and reliable performance in demanding industrial environments.
