Also known as centre hole cylinder, hollow plunger, hollow piston or hollow ram cylinders. They are used for tensioning, load testing, bush extraction, and maintenance applications. Available in single acting - spring return, double acting (improves the speed of operation when longer cylinder strokes are required) and aluminium (lightweight for ease of portability - in both single or double-acting).
