HCR2504 Enerpac 250 Ton Double-Acting High-Tonnage Cylinder, 3.94 in Stroke, 286 Ton Max Capacity

The Enerpac HCR2504 is a 250-ton class double-acting cylinder from the HCR-Series high-tonnage range, with a 3.94 in stroke and a maximum capacity of 286 tons at 10,150 psi. As a double-acting cylinder it is powered in both directions, for fast advance and retract and for applications where there is no load to push the plunger back, such as pushing, pressing and pulling.

Features

• Hardened surface that resists side-loading and cyclic wear
• Designed to withstand up to 10% side-load of maximum capacity
• Fast advance and retract
• Weather protected, inside and out
• Upper and lower replaceable bearings support the plunger throughout the stroke
• Certified lifting eyes, base mounting holes and collar threads

Sizing

The HCR2504 has an effective area of 56.27 in² and needs 221.55 in³ of oil to advance its full stroke and 83.04 in³ to retract. It is 11.46 in tall collapsed and about 15.40 in extended. Choose a pump with at least 244 in³ of usable oil; a ZE pump with a 1.2 gal (277 in³) reservoir or larger covers a single cylinder. Under full load, a ZE4 pump (60 in³/min at 10,000 psi) takes about 3.7 minutes to complete the stroke and a ZE5 (120 in³/min) about 1.8 minutes; under light load two-stage pumps move it much faster.

How it compares

The HCG2504 is the single-acting, load-return version with the same capacity and stroke. Other strokes in the 250-ton HCR range: HCR2502 (1.97 in), HCR2506 (5.91 in), HCR2508 (7.87 in), HCR25010 (9.84 in), HCR25012 (11.81 in).

Before you order: Keep side-load below 10% of maximum capacity; a collar thread is standard on this 250-ton class.
