PowRLock - Hollow Pistons - Single Acting

Hollow Piston
PowRlock hollow piston heads are the easiest and most versatile of all heads to mount. They accommodate and are mounted over any length bolt, stud, or rod which passes through the hollow piston for easiest installation. They can be installed to act in either a push or a pull motion. The exclusive patented PowRlock hollow piston head asserts forces up to 24,000 pounds.

By removing the internal spring, stroke is approximately doubled, oil volume required also approximately doubled

Do not allow unrestricted piston travel beyond 90% of maximum stroke
