CDT27251 Enerpac Double-Acting Threaded Body Cylinder, 6,110 lb Push / 4,080 lb Pull, 0.97 in Stroke

The Enerpac CDT27251 is a double-acting threaded body cylinder from the CDT series. Hydraulic pressure drives it both ways, giving 6,110 lb pushing and 4,080 lb pulling at 5,000 psi over a 0.97 in stroke. Because the retract stroke is powered, you can fit clamping accessories to the plunger for push and pull action, and it suits high-cycle work such as production punching.

Features

• 2.125-16 UN threaded body for exact height positioning
• Center-tapped plunger (.375-16 UNC) for attachments
• Powered retract: better control in the unclamp cycle and less sensitive to back pressure from long tube runs
• SAE #4 oil ports
• Buna-N and polyurethane seals

Sizing

Effective area is 1.22 in² pushing and 0.82 in² pulling. A full stroke uses 1.20 in³ to advance and 0.81 in³ to retract. Length is 3.23 in retracted and 4.20 in extended; weight 3.1 lb. Workholding circuits often run below 5,000 psi; at 2,000 psi this cylinder gives about 2,440 lb of push and at 3,000 psi about 3,660 lb.

How it compares

Other strokes at 6,110 lb: CDT27151 (0.57 in), CDT27501 (1.96 in). For a simpler single-line circuit, the single-acting CST series offers spring-return equivalents.

Before you order: Control it with a 4-way valve so both ports are powered; mounting flanges and flange nuts for the body thread are sold separately.
