Center Hole Hydraulic Cylinders (also known as hollow plunger cylinders) are high-force hydraulic cylinders featuring a hollow bore that runs through the center of the piston and rod. This design allows threaded rods, cables, anchor bolts, or tendons to pass directly through the cylinder, making them essential for tensioning, pulling, testing, and controlled lifting applications in professional rental environments.
In hydraulic rentals, center hole cylinders are most commonly used where linear force must be applied to an existing rod or cable, rather than lifting from a flat surface.
Center hole cylinder rentals provide access to specialized equipment for project-specific needs without the cost, storage, or maintenance requirements of ownership.
Center hole cylinders are fully compatible with standard 10,000 PSI hydraulic systems from Enerpac, Simplex, and Power Team when properly matched.
Center hole cylinders allow precise tensile force to be applied directly along the bolt axis, ensuring accurate preload without inducing bending or misalignment.
Center hole cylinders typically require a compatible hydraulic pump, hoses, pressure gauge, and appropriate threaded adapters or fixtures.
Center hole cylinders can apply pushing force, but they are most commonly selected for tensioning and pulling operations where centerline force application is required.
Center hole cylinders are commonly used for pulling, tensioning, and detensioning applications when properly configured with threaded adapters and reaction fixtures.
Center hole cylinders feature a hollow bore that allows force to be applied through threaded rods or cables, enabling pulling and tensioning applications that standard cylinders cannot perform.
Center hole cylinders operate at a maximum working pressure of 10,000 PSI and are designed for use with compatible high-pressure hydraulic systems.
