PowRlock Single-Acting Hollow Pistons deliver exceptional holding and punching power in a compact, easy-to-integrate design. Small enough to fit in the palm of your hand yet capable of generating clamping and punching forces up to 27,500 pounds, these units provide a versatile solution for a wide range of manufacturing and workholding applications. Their hollow piston design allows for flexible installation over bolts, studs, or rods, making them ideal for custom fixture and tooling setups.

More than a simple hydraulic cylinder, PowRlock Single-Acting Hollow Pistons are engineered to help manufacturers create specialized clamping systems using existing fixtures and equipment. Their high holding force, dependable performance, and adaptable design make them suitable for machining, assembly, punching, and other production processes where precision, reliability, and efficiency are critical.

PowRlock Hollow Piston Heads are among the easiest and most versatile workholding solutions to install and operate. Designed to mount over any length bolt, stud, or rod that passes through the hollow piston, they provide exceptional flexibility for a wide range of clamping applications. These patented piston heads can be configured to deliver either pushing or pulling forces and are capable of exerting up to 24,000 pounds of force for reliable, high-performance operation.

PowRlock Hollow Piston Heads help improve production efficiency by simplifying tooling, reducing indirect labor, and minimizing rework. Their precision clamping capabilities support consistent repeatability and enhanced quality control, while their versatility allows manufacturers to integrate machining center capabilities into a variety of applications. The result is faster production, improved accuracy, and more streamlined manufacturing processes.

PowRlock Hydraulic Swing Clamps are designed to automate simple fixture setups while providing reliable and efficient workpiece clamping. Featuring a unique sequential motion, the clamping arm rotates 90 degrees over the workpiece before applying a downward clamping stroke with forces up to approximately 5,000 pounds. This design allows for unobstructed loading and unloading while delivering consistent clamping performance for a wide range of machining and manufacturing applications.

When paired with a Wilton booster or pump, a simple valve operation activates the clamping cycle, while releasing the valve causes the arm to swing clear of the work area and return to its rest position. Standard models provide clockwise arm rotation, with counterclockwise movement available through a simple adjustment. Their automated operation helps improve productivity, reduce setup time, and streamline fixture design in demanding production environments.

PowRlock Hydraulic Support Jacks are designed to provide stable support for large workpieces during machining operations, helping prevent deflection, vibration, and distortion. The spring-loaded piston automatically extends when not under load, allowing the support point to adjust easily to the workpiece. Once hydraulic pressure is applied, the jack delivers reliable support forces of up to 5,000 pounds, making it ideal for precision manufacturing and workholding applications.

These support jacks automatically compensate for variations in material thickness, simplifying setup and improving machining consistency. The support force can be easily adjusted by controlling hydraulic pressure, providing the flexibility needed for a wide range of workpiece sizes and weights. Their dependable operation helps improve part quality, reduce machining errors, and enhance overall production efficiency.

PowRlock Single-Acting Boosters provide a dependable and economical solution for hydraulic pressure intensification in air-over-oil systems. Designed with automatic feed functionality, these rugged units deliver reliable performance for a variety of hydraulic clamping, holding, and workholding applications. Their durable construction and efficient operation make them well-suited for manufacturing environments where consistent hydraulic force is required.

Ideal for simple hydraulic intensification setups, PowRlock Single-Acting Boosters help increase system pressure while maintaining ease of operation and long service life. For optimal performance and seal longevity, these boosters are designed for use with medium aniline hydraulic fluid having a viscosity range of 100–200 SSU. Their proven reliability and low operating costs make them a practical choice for a wide range of industrial applications.
