It installs into a threaded bore and is secured with standard flange nuts, making it well-suited for support, clamping, and workpiece ejection tasks. The cylinder delivers 980 lbf of push capacity at a rated operating pressure of 5000 psi, with a stroke length of 31\/32 inches. Its compact form factor allows multiple units to be positioned close together, enabling clamping or support across long workpieces or in space-constrained high-pressure setups. Hydraulic technicians and fixture engineers are the primary installers in manufacturing and fabrication environments.\u003c\/p\u003e\u003cp\u003eThe cst4251 is used in production fixturing, machining setups, and assembly line clamping applications where precise, repeatable force is required. The threaded body design integrates directly into custom fixtures and tooling plates, eliminating the need for external mounting brackets. It is particularly effective in applications that demand multiple cylinders operating in close proximity along a workpiece, such as in press tooling or multi-point clamping fixtures. Its 3\/4 inches-16 UNF thread makes it compatible with standard threaded bore fixtures machined to that specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e980 lbf push capacity at 5000 psi rated pressure\u003c\/li\u003e\n\u003cli\u003e31\/32 inch stroke length for compact actuation\u003c\/li\u003e\n\u003cli\u003e3\/4 inches-16 UNF threaded body for direct fixture integration\u003c\/li\u003e\n\u003cli\u003eSecured with standard flange nuts — no specialty hardware required\u003c\/li\u003e\n\u003cli\u003eCompact design allows close-spacing for multi-point clamping\u003c\/li\u003e\n\u003cli\u003eSuitable for support, clamping, and workpiece ejection tasks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for installation in threaded-bore fixtures machined to accept a 3\/4 inches-16 UNF threaded body hydraulic cylinder.

Before servicing or installing this cylinder, depressurize the hydraulic circuit completely and verify system pressure is at zero. Thread the cylinder body into the prepared bore and secure with standard flange nuts to the appropriate engagement depth. Do not exceed the rated system pressure of 5000 psi, and ensure all hydraulic fittings and lines are rated for the operating pressure before pressurizing the circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePush Capacity\u003c\/strong\u003e: 980 lbf at 5000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Pressure\u003c\/strong\u003e: 5000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroke Length\u003c\/strong\u003e: 31\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4 inches-16 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.55 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ENERPAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: cst4251\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ENERPAC","offers":[{"title":"Default Title","offer_id":51525466882354,"sku":"CST4251","price":280.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8434093e4fe4acaa71d35fb0afb05b37.jpg?v=1785474640","url":"https:\/\/voomisupply.com\/products\/enerpac-cst4251-hydraulic-cylinder-980-lbf-5000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
