CSA Series Single-Acting Heavy-Duty Jack

The CSA series single-acting heavy-duty hydraulic jack is engineered for applications requiring higher load capacity than standard CS series jacks, featuring reinforced structural components and an expanded dimensional envelope to handle the greater forces involved in heavy machinery lifting, large structural alignment, and industrial pressing operations. Spring return provides automatic piston retraction upon pressure release, maintaining cycle efficiency for repetitive operations.

The heavy-duty construction uses higher-grade materials and increased wall thicknesses in critical structural areas including the cylinder barrel, piston rod, and base plate, ensuring the jack maintains stable performance and structural integrity at rated capacity throughout its service life. All wetted surfaces and sealing systems are designed for long-term hydraulic fluid compatibility, and the close-tolerance cylinder bore and piston rod guide system minimizes side-load sensitivity for stable performance under eccentric loading conditions that are common in real-world lifting applications.

Standard NPT 3/8 quick-connect fittings and dust caps are fitted as on the CS series. The baked-paint surface finish provides corrosion resistance for outdoor and industrial site use. The CSA is suitable for bridge maintenance lifting points, heavy equipment installation and leveling, large press die setting, structural concrete formwork support, and other applications where the standard CS series capacity is insufficient but single-acting spring-return operation remains appropriate for the retraction force and speed required.
