HCR50012 Enerpac 500 Ton Double-Acting High-Tonnage Cylinder, 11.81 in Stroke, 575 Ton Max Capacity

The Enerpac HCR50012 is a 500-ton class double-acting cylinder from the HCR-Series high-tonnage range, with an 11.81 in stroke and a maximum capacity of 575 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 HCR50012 has an effective area of 113.25 in² and needs 1,337.55 in³ of oil to advance its full stroke and 438.9 in³ to retract. It is 23.39 in tall collapsed and about 35.20 in extended. Choose a pump with at least 1,471 in³ of usable oil; a ZE pump with a 10.3 gal (2,379 in³) reservoir or larger covers a single cylinder. Under full load, a ZE4 pump (60 in³/min at 10,000 psi) takes about 22.3 minutes to complete the stroke and a ZE5 (120 in³/min) about 11.1 minutes; under light load two-stage pumps move it much faster.

How it compares

The HCG50012 is the single-acting, load-return version with the same capacity and stroke. Other strokes in the 500-ton HCR range: HCR5002 (1.97 in), HCR5004 (3.94 in), HCR5006 (5.91 in), HCR5008 (7.87 in), HCR50010 (9.84 in).

Before you order: Keep side-load below 10% of maximum capacity; on 500-ton models the collar thread is optional: order HCR50012E002 for a cylinder with collar thread.
