HCR20012 Enerpac 200 Ton Double-Acting High-Tonnage Cylinder, 11.81 in Stroke, 223 Ton Max Capacity

The Enerpac HCR20012 is a 200-ton class double-acting cylinder from the HCR-Series high-tonnage range, with an 11.81 in stroke and a maximum capacity of 223 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 HCR20012 has an effective area of 43.95 in² and needs 519.06 in³ of oil to advance its full stroke and 237.24 in³ to retract. It is 20.00 in tall collapsed and about 31.81 in extended. Choose a pump with at least 571 in³ of usable oil; a ZE pump with a 2.6 gal (601 in³) reservoir or larger covers a single cylinder. Under full load, a ZE4 pump (60 in³/min at 10,000 psi) takes about 8.7 minutes to complete the stroke and a ZE5 (120 in³/min) about 4.3 minutes; under light load two-stage pumps move it much faster.

How it compares

The HCG20012 is the single-acting, load-return version with the same capacity and stroke. Other strokes in the 200-ton HCR range: HCR2002 (1.97 in), HCR2006 (5.91 in), HCR2008 (7.87 in), HCR20010 (9.84 in).

Before you order: Keep side-load below 10% of maximum capacity; a collar thread is standard on this 200-ton class.
