hollow plunger cylinders

The BMSH-series is a spring return hollow piston rod cylinder. The hollow piston allows for a rod or cable to be inserted through the entire body length. They can be used in tensioning, load testing and bush extracting and maintenance applications. All BMSH-Series cylinders feature a hard chrome cylinder bore and piston rod for maximum corrosion resistance and a bronze overlay piston bearing area to reduce scoring and increase service life. All cylinders incorporate a bolt on removable steel base plate for extra protection.

The hollow piston allows for a rod or cable to be inserted through the entire body length, while the double acting design improves speed of operation when longer stroke cylinders are required. They can be used in tensioning, load testing, bush extracting, and maintenance applications. All cylinders in this range have base mounting holes.

The BELIUM BASH-Series hollow plunger aluminum cylinder design provides both push and pull forces. Lightweight aluminum cylinders offer portability and versatility. The BASH-Series are designed for maximum cylinder life as each unit has all surfaces coated with Hard oxidation. Cylinder life is further extended by composite bearings that also increase side load resistance.

The BASH-Series hollow plunger cylinder sports rapid cylinders retraction courtesy of a high-strength return spring. Load-induced damage and wear is minimized with a steel baseplate and saddle design. BELIUM hollow plunger aluminum cylinders are capable of handling the full cylinder capacity; the integral stop ring prevents over-travel of the plunger. All BASH-Series models include standard handles for easy handling.
