Enerpac - Model RACH202, 229 kN -Aluminum Hollow Plunger Hydraulic Cylinder for Tensioning and Lifting

SHARE

The RACH-Series Aluminum Hollow Plunger Hydraulic Cylinders are engineered with a hollow plunger featuring an internal thread, providing adaptability for various mechanical applications such as tensioning, testing, pulling, and lifting. With a capacity of 229 kN and a 50 mm stroke, these cylinders are designed to offer reliability in demanding environments. Rated for 10,000 psi (700 bar), each cylinder adheres to the ASME B30.1 safety standards, ensuring operational safety and efficiency. The single-acting design employs a high-strength return spring allowing for fast retraction, while the bolt-on hardened steel saddles and steel base plate enhance durability. Constructed from aluminum, these cylinders are lightweight and less susceptible to corrosion, making them suitable for use in caustic environments. The anodized hard coat finish further extends their durability by resisting damage over time.

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.
