Part of the Simplex RFS Series Flat Jack line, it delivers 30 tons of capacity with a 0.5-inch stroke. A built-in return spring rapidly retracts the plated plunger to its starting position once hydraulic pressure is released, improving cycle efficiency. The exterior carries an enamel coating for corrosion resistance and extended service life. A wiper seal protects the internal cylinder assembly from dirt, moisture, and other contaminants during use.\u003c\/p\u003e\n\u003cp\u003eThe rfs30 is suited for maintenance, alignment, and lifting tasks in industrial and mechanical service environments where vertical clearance is severely limited. Typical applications include machinery leveling, bridge and structural maintenance, press and die work, and any scenario where a low-profile hydraulic tool is required. This cylinder is normally installed and operated by millwrights, hydraulic technicians, and heavy equipment service professionals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e30-ton hydraulic capacity in a low-height flat jack form factor\u003c\/li\u003e\n  \u003cli\u003e0.5-inch stroke designed for tight-clearance applications\u003c\/li\u003e\n  \u003cli\u003eSingle-acting operation with a powerful internal return spring for fast plunger retraction\u003c\/li\u003e\n  \u003cli\u003eChrome-plated plunger resists wear and corrosion\u003c\/li\u003e\n  \u003cli\u003eEnamel-coated exterior extends cylinder service life\u003c\/li\u003e\n  \u003cli\u003eWiper seal protects internal assembly from dirt, moisture, and contaminants\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-application flat jack cylinder for single-acting hydraulic systems requiring low-profile tooling in the 30-ton capacity range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified hydraulic technicians or millwrights familiar with high-force hydraulic tooling. Always depressurize the hydraulic system completely before connecting or disconnecting the cylinder. Ensure the work surface and saddle are stable and rated for the applied load before pressurizing.
