4×24 Hydraulic Cylinder – AMRAP HYDRAULICS

The 4×24 Hydraulic Cylinder from AMRAP HYDRAULICS is a welded, double-acting unit designed for demanding industrial tasks. It features a 4-inch bore (OD 4.38″), a 24-inch stroke, and a 2-inch rod. Retracted length is 34 inches and extended length is 58 inches, with 1.5-inch pin holes. This cylinder uses SAE 8 ports (O-ring boss) and is rated for 3500 PSI. The column load capacity is listed at 37,690 lbs. Its all-welded steel construction emphasizes durability, corrosion resistance, and outdoor performance. High-quality seals help minimize leakage and prevent rust particles from entering critical pathways.
This model is well-suited for heavy lifting, quill-style modifications, and machines requiring a compact but rugged power unit. The welded design helps ensure leak-free operation under high-stress cycles, while the compact seals reduce maintenance needs over time. Consider compatible mounting options and space for full extension when planning installation.
2×4 Hydraulic Cylinder – AMRAP HYDRAULICS

This 2×4 model offers a smaller bore while retaining the welded double-acting design and robust SAE 6 port configuration. With a 2-inch bore, 4-inch stroke, and a 1.25-inch rod, it remains practical for lighter-duty equipment or auxiliary hydraulic systems. The retracted length is 12 inches, and extended length is 16 inches, with 1″ pin holes. The unit is rated for 3500 PSI and provides a column load capacity of 9,420 lbs. Built for corrosion resistance and harsh outdoor use, it uses compact seals to minimize leakage and protect internal components.
Ideal for smaller machines, agricultural attachments, and retrofit projects where space or load requirements favor a compact cylinder with strong performance characteristics. Verify mounting compatibility and ensure adequate clearance for full stroke during operation.
Magister Hydraulics 4×24 Clevis

The Magister Hydraulics 4×24 Clevis cylinder is manufactured as a welded, double-acting unit rated at 3500 PSI with a 4-inch bore and 24-inch stroke. Outer diameter measures around 4.5 inches, with a 2-inch rod diameter. Retracted length is approximately 34.25 inches, extended to 58.25 inches. Ports use SAE 8 (O-ring boss). This model emphasizes being a manufacturer-owned design, focusing on reliability for heavy-duty use. The high column load rating (about 36,000 lbs) supports substantial force requirements in industrial settings.
Suitable for heavy machinery, agricultural implements, and fleet repair applications where consistent, long-lasting performance is essential. Ensure mounting alignment with clevis ends and verify compatibility with existing hydraulic circuits and valves.
Magister Cross Tube 4×30

The Magister Cross Tube 4×30 cylinder expands the stroke to 30 inches while maintaining a 4-inch bore. It is a welded hydraulic cylinder with a 2-inch rod diameter and an extended length of up to 70 inches, retracted length around 40 inches, and SAE 8 ports (O-ring boss). This unit is designed to handle demanding duties with a 3500 PSI rating and a column load capacity near 32,000 lbs. As with similar models, Magister emphasizes being a manufacturer rather than a reseller, which often correlates with tighter quality control and direct support.
Consider this option when long reach is critical for machine tools, construction equipment, or trailer-mounted hydraulic systems. Check mounting compatibility, end fittings, and any required protective coatings for outdoor environments.
2×4 Hydraulic Cylinder – AMRAP HYDRAULICS

This compact 2×4 cylinder from AMRAP HYDRAULICS delivers a 2-inch bore, 4-inch stroke, and 1 1/8-inch rod diameter. It uses SAE 6 ports (Female Pipe) and supports up to 3000 PSI. The unit accommodates a column load of 9,420 lbs and is designed for welded clevis mounting. It is widely applicable to industrial machinery, farming equipment, and construction tools where a smaller actuator is beneficial for precise movements and compact installations.
When selecting this size, ensure hydraulic circuit compatibility with SAE 6 ports and confirm that the cylinder’s extension and retraction force aligns with the load profile and safety requirements of the application.
Buying Guide: Key Purchase Considerations
- Bore and stroke: A 4-inch bore provides substantial force; match the stroke length to the intended travel distance. Longer strokes increase reach but may require additional mounting space and energy.
- Ports and fittings: SAE port sizes (8, 6, etc.) determine fluid routing and valve compatibility. Verify port type (O-ring boss or pipe) and thread standard to avoid leaks and misfits.
- Rated pressure and load capacity: Look for cylinders rated around 3500 PSI for heavy-duty tasks. Compare column load capacity to your anticipated loads to prevent failure under peak conditions.
- Construction: All-welded designs with heavy-duty steel construction offer durability and corrosion resistance; ensure outdoor or abrasive environment suitability if applicable.
- End fittings: Clevis vs. cross-tube ends affect mounting options and alignment. Confirm compatibility with existing hardware or the need for adapters.
- Seals and maintenance: High-quality seals reduce leakage and particulate ingress. Consider ease of seal replacement and availability of spare parts.
- Manufacturer vs reseller: Direct-manufacturer designs may provide tighter quality control and better support. Assess warranty terms and customer service reputation.
- Installation space: Account for retract and extended lengths, including clearance for full stroke, mounting hardware, and any protective sleeves or guards.
- Applications: Choose a cylinder suited to load type (lifting, pushing, pulling, bending) and environment (outdoor exposure, corrosion risk, contamination).
- Compatibility with systems: Ensure valve, pump, and reservoir capacities align with the cylinder’s flow requirements to achieve smooth operation and avoid cavitation.
This selection provides multiple 4-inch bore hydraulic cylinders from reputable brands, emphasizing welded, double-acting designs and robust port configurations. When choosing, consider mounting style, stroke needs, and environmental conditions to optimize performance and longevity. Always consult the product’s technical specifications and, if needed, request engineering guidance from the manufacturer or distributor to verify suitability for your specific application.
