Details

RACH-Series Hollow Plunger Hydraulic Cylinders (sometimes called center-hole cylinders) feature a hollow plunger with an internal thread to allow fixing to the component to be pulled. This makes them the ideal choice for when you need a lighter, more portable cylinder for applications such as tensioning, testing, pulling, and lifting. Each RACH Cylinder is rated for up to 10,000 psi (700 bar) and compliant with ASME B30.1.

Each RACH Cylinder is single-acting and uses a high-strength return spring for rapid retraction. All are equipped with bolt-on hardened steel saddles and a steel base plate for increased durability.

Aluminum is not only lightweight, but also inherently less corrosive than steel, which makes it a great material for use in many caustic environments. For enhanced protection, RACH Aluminum Cylinders are finished with an anodized hard coat finish to resist damage and extend cylinder life.

Feature

Hollow plunger design allows for both pull and push forces
Composite bearings increase cylinder life and side load resistance
Hard coat finish on all surfaces resists damage and extends cylinder life
Handles included on all models
Floating center tube increases seal life
Steel baseplate and saddle for protection against load-induced damage
Integral stop ring prevents plunger over-travel and is capable of withstanding the full cylinder capacity
High-strength return spring for rapid cylinder retraction
CR400 coupler and dustcap included on all models
All cylinders meet ASME B-30.1 standards
