Zupper Aluminum Hydraulic Cylinder 20-Ton 100mm RAC-20100

Executing continuous, long-reach lifting operations in elevated or restricted environments presents strict logistical parameters. Utilizing a standard steel cylinder capable of a 100mm stroke introduces a significant increase in dead load. This excess weight elevates operational safety risks for technicians maneuvering equipment on scaffolding or within confined ship hulls. Attempting to substitute with a short-stroke cylinder requires unstable cribbing blocks to achieve the specified distance.

The Zupper aluminum hydraulic jack RAC-20100 addresses these structural limitations. Engineered from aerospace-grade aluminum alloy, this extended-stroke cylinder achieves a maximum rated load capacity of 20 tons across a full 100mm of travel, while maintaining a substantially lower dead load compared to its steel equivalents. It is an optimized solution for high-altitude and offshore engineering tasks requiring extended linear push without excessive manual handling risks.

Extended reach and dead load reduction

Implementing the extended 100mm RAC series streamlines the approach to structural alignments and heavy component separation:

• Single-pass continuous extension: The 100mm plunger travel permits technicians to tension cables or separate industrial structures in a single operational phase. This eliminates the repetitive cycle of pressurizing, inserting temporary supports, and resetting the hydraulic system.

• Optimized deployment safety: With a dead load of only 4.6 kg, the RAC-20100 minimizes the physical exertion required during manual positioning. Additionally, the hard-coat anodized aluminum surface resists saltwater and extreme humidity, ensuring compliance with offshore rig maintenance standards.

Dynamic stability and side-load management

Extending a cylinder ram to 100mm under its maximum rated load capacity inherently increases mechanical stress. To manage these forces and prevent internal seal failure, the RAC-20100 incorporates specific structural safeguards:

• Hardened load distribution: The baseplate and the top plunger saddle are constructed from high-carbon steel. This hybrid architecture ensures the aluminum body avoids direct abrasive damage from concrete or uneven steel surfaces.

• Side-load tolerance: To protect the internal chamber when the 100mm plunger is fully exposed, the cylinder utilizes advanced composite guide rings. These bearings prevent metal-to-metal scoring and allow the extended ram to safely accommodate off-center loads of up to 10% of its maximum rated load capacity.

Technical specifications

Required high-volume power source: Zupper CP-700 manual pump

Operating a 100mm extended cylinder requires a dependable, high-volume fluid source. Because the RAC-20100 requires over 300cc of oil to fully extend the chamber, utilizing low-capacity pumps will result in system cavitation and pressure drops.

We mandate operating this cylinder in conjunction with the Zupper CP-700 manual hydraulic pump. Equipped with a sufficient internal oil reservoir and a dual-stage pumping mechanism, the CP-700 rapidly fills the extended aluminum chamber before shifting into the high-pressure lifting phase—ensuring a closed-loop and controlled hydraulic system. Click here to view Zupper CP-700 manual pump specifications and pricing.
