Metric Hydraulic Cylinders - Heavy Duty Industrial,
Tie Rod - MHP Series

MHP Series Metric Hydraulic Cylinders, tie rod construction, are rated at 210 Bar. Requirements of ISO 6020/2 (2006), 160 Bar Compact Series are met, and the cylinders are designed to deliver long, efficient service with low maintenance requirements.

Miller MHP Series Metric Hydraulic Cylinders, tie rod construction, are designed to meet the requirements of ISO 6020/2 (2006), 160 Bar Compact Series. MHP Series cylinders may be used for working pressures up to 210 Bar. They are available in 12 standard mounting styles and bore sizes ranging from 25mm to 200 mm, in any practical stroke length and seal types to suit a wide variety of operating environments.

MHP Series Hydraulic Cylinders are the true world standard. Whether you or your machine are in Europe, Asia, South America, Canada, Mexico, or the United States, you can rely on the engineering expertise, manufacturing experience, and commitment to quality that you've come to expect from Miller.

In addition to worldwide support, MHP Series incorporates a multitude of innovative design features that increase machine productivity through reduced downtime and provide improved system efficiency because of faster cycle times. Design features such as nodular iron rod bushing, hard chrome plated piston rods, and stepped cushions provide increased machine productivity. Lipseal™ piston is standard on 25mm, 32mm and 40mm bore sizes, and provides zero leakage under static conditions for hydraulic pressures up to 210 Bar. The Miller B style piston, standard on 50mm and larger bore sizes, is a single seal design which incorporates two wear strips. This design provides smooth operation, long bearing life, and high load carrying capacity. The Tuff Rod Seal in combination with the standard polyurethane Double-Service Wiperseal™ comprises a sealing system that delivers dry rod performance. Pressure actuated o-ring Body End Seals provide leak free service.

Every MHP Series cylinder is individually tested before leaving our plant to assure proper performance and leak free operation and comes with an eighteen month warranty.
