Enerpac CDT40251 39.1 kN Threaded Cylinder

CDT40251 is a double-acting, threaded-body hydraulic cylinder from the Enerpac CDT series in the Workholding Tools line. It has an inch UN-threaded body. With a steel body and solid plunger, it is used for push and pull applications. At a maximum operating pressure of 5,000 psi (≈345 bar) it delivers 8,800 lbf (≈39.1 kN) push and 5,870 lbf (≈26.1 kN) pull force over a 0.99 in (≈25.1 mm) stroke. Effective area is 1.76 in² (≈11.35 cm²) advance and 1.17 in² (≈7.55 cm²) retract. Oil capacity is 1.73 in³ (≈28.3 cm³) advance and 1.15 in³ (≈18.8 cm³) retract. The body thread is 2.500-16 UN and the plunger thread is .500-13 UNC. Extended height (A) is 4.55 in (≈115.6 mm), retracted height (B) is 3.56 in (≈90.4 mm), and weight is 4.6 lb (≈2.1 kg). It is suited to clamping, supporting and positioning workpieces in fixtures, welding jigs and assembly tooling. The double-acting design is recommended for high-cycle applications.
