RAC Series Aluminum Cylinders
Lightweight single-acting hydraulic cylinders of the RAC series are equipped with a heavy-duty return spring for fast retraction and an integrated stop ring to prevent excessive plunger travel. All are equipped with hardened steel saddles, and a steel base plate is standard on 20-ton and larger models.
Enerpac aluminum hydraulic cylinders, weighing about half that of their steel counterparts, combine an impressive power-to-weight ratio with the convenience of easier transport and positioning. They have a pressure rating of 10,000 psi (700 bar) and comply with the ASME B30.1 standard.
Aluminum is not only lightweight but also inherently less corrosive than steel, making it an excellent material for use in many harsh environments. To provide better protection, RAC aluminum cylinders are finished with an anodized hard coating that is resistant to damage and extends the cylinder's life.
Enerpac RAC series hydraulic cylinders – lightweight single-acting aluminum cylinders (700 bar)
Enerpac RAC series hydraulic cylinders (lightweight single-acting aluminum cylinders with return spring, Enerpac Aluminum Single-Acting Cylinders) are innovative hydraulic power devices designed to provide maximum mobility, low dead weight, and high efficiency during lifting and assembly work. The construction made of high-strength aluminum alloy guarantees strength parameters comparable to steel with a significant reduction in device weight. RAC series cylinders operate at a maximum working pressure of 700 bar (70 MPa), offering a lifting capacity range from 10 to 150 metric tons (from 88 kN to 1589 kN) and stroke lengths from 50 mm to 250 mm. Equipped with advanced composite bearings, they eliminate direct metal-to-metal contact, significantly increasing resistance to side loads of up to 10% and extending seal life. The integrated stop ring prevents excessive plunger extension at full load, and the hardened outer coating effectively protects the housing against mechanical damage and corrosion, making Enerpac RAC cylinders an indispensable tool in construction, mining, machine service, and work in hard-to-reach places.
Application and technical characteristics of Enerpac RAC series cylinders
Enerpac RAC lightweight aluminum cylinders were created for applications requiring frequent equipment transport and work at heights or in tight technological spaces. They are commonly used for positioning structure elements, lifting machinery, infrastructure maintenance, and assembly work.
- Low dead weight and high mobility: Made from aluminum alloy with the strength of steel, allowing the device to be easily maneuvered by a single operator.
- Composite bearings and side load resistance up to 10%: Protect working surfaces from abrasion and seizing when lifting off-center loads.
- Integrated stop ring (Stop Ring): Provides protection against accidental plunger expulsion and carries the full nominal load of the cylinder.
- Base plate and hardened steel components: A steel base plate (standard on models from 20 to 150 tons) and a steel saddle protect the aluminum body from dents and wear.
- High-efficiency return spring: Ensures fast and smooth plunger return to the starting position after pressure release.
- CR-400 high-flow coupler: Standard equipment with a coupler and dust cap allowing quick connection to the power system.
Why choose Enerpac RAC series cylinders at the HYDRON store?
As an official distributor of Enerpac equipment, the HYDRON store provides 100% original RAC series hydraulic cylinders, manufactured according to strict ASME B30.1 criteria. Their lightweight and durable construction drastically reduces operator fatigue during intensive field work. For optimal performance and mobility, it is recommended to pair aluminum cylinders with lightweight Enerpac hand pumps (e.g., P-392 or P-802). To create a safe and reliable pressure station, we recommend choosing other compatible products from our offer, such as original Enerpac hydraulic tools and cylinders, efficient 700 bar hydraulic pumps, flexible high-pressure hydraulic hoses and leak-free 700 bar hydraulic quick-couplers.

Frequently Asked Questions (FAQ)
What are Enerpac RAC series aluminum hydraulic cylinders used for?
RAC series cylinders are used for lifting, positioning, and assembly of machinery and structural elements in applications where low equipment weight and ease of transport are crucial.
How do RAC aluminum cylinders differ from traditional RC steel cylinders?
RAC aluminum cylinders are significantly lighter (up to 50% compared to RC steel counterparts with the same capacity), which facilitates transport and handling by a single operator. They also feature a hardened outer coating protecting the aluminum body.
Do RAC aluminum cylinders have protection against seizing under side loads?
Yes. The use of special composite bearings prevents direct metal-to-metal contact inside the cylinder, protecting the plunger and body from seizing even with side loads reaching up to 10% of the capacity.
Which hydraulic pumps work best with the RAC series cylinders?
For RAC aluminum cylinders, it is recommended to use lightweight Enerpac hand pumps, such as the two-stage P-392 or P-802 pumps, allowing for a fully mobile, lightweight lifting set.
