Simplex r51 Hydraulic Cylinder 5 Ton 1 Inch Stroke

Product Description

The SIMPLEX r51 is a single-acting hydraulic cylinder designed for high-force lifting, pushing, and pressing applications across industrial and construction trades. Rated at 5 tons of capacity with a 1-inch stroke, it operates at a maximum pressure of 10,000 psi. An internal spring provides fast piston retraction once pressure is released, reducing cycle time during repetitive use. The chrome-plated piston rod resists scoring and corrosion, and a rod wiper keeps the cylinder bore clear of dirt, water, and rust. This cylinder is built for demanding environments where reliable, controlled force application is required.

The r51 is suited for maintenance, fabrication, and field service work where a compact, high-pressure cylinder is needed. Typical applications include structural alignment, equipment repair, and press-fit assembly. A stop ring provides blow-out protection for the piston rod, adding a critical safety layer during high-pressure operation. The included heat-treated load saddles protect work surfaces and distribute load evenly. Ram half high-flow quick couplers are included and plated for corrosion resistance, making connection to a hydraulic pump straightforward in the field.

Key Features

• 5-ton capacity with a 1-inch stroke for compact, high-force applications
• Maximum operating pressure of 10,000 psi
• Internal spring for automatic fast piston retraction
• Chrome-plated piston rod resists scoring and corrosion
• Rod wiper seals the cylinder bore against dirt, water, and rust
• Stop ring prevents piston rod blow-out during pressurized operation
• Includes heat-treated load saddles and plated high-flow quick couplers

Compatibility

Designed as an OEM-style single-acting hydraulic cylinder compatible with standard 10,000 psi hydraulic hand, air, or electric pump systems using high-flow quick-connect couplers.

Installation Notes

Hydraulic cylinder installation and operation should be performed by qualified personnel familiar with high-pressure hydraulic systems. Always depressurize the hydraulic circuit completely before connecting or disconnecting the cylinder. Ensure the cylinder is positioned on a stable, level surface with the load saddle properly seated before applying pressure. Do not exceed the rated 10,000 psi maximum operating pressure of the system.
