CHT SERIES HYDRAULIC CYLINDERS
Grices CHT Series Hydraulic Cylinders, compliant with ISO 6020/2 and DIN 24554, integrate a magnetostrictive position transducer that detects the piston rod position without contact. Designed for demanding environments, they ensure wear-free operation and high reliability. They operate at a nominal pressure of 16 MPa, with bore sizes from 40 to 200 mm and strokes of up to 4000 mm. Analogue or digital outputs are available. The available product codes are: CHT/40, CHT/50, CHT/63, CHT/80, CHT/100, CHT/125, CHT/160, CHT/200.
The Grices CHT Series Hydraulic Cylinder range is designed in strict compliance with ISO 6020/2 and DIN 24554 standards for the compact 160 bar series. The square end-cap architecture with tie rods provides the structural rigidity required for high-performance industrial applications where compact dimensions are essential. The main innovation of this series is the integration of a linear position transducer based on magnetostrictive technology. This system enables continuous and accurate piston rod position detection without any physical contact between the moving internal components. The absence of friction eliminates wear, ensuring an extended service life even in demanding working environments and drastically reducing routine and extraordinary maintenance requirements.
Operating performance includes a continuous nominal pressure of 16 MPa (160 bar), with the ability to withstand maximum pressure peaks of up to 25 MPa. The dimensional range is highly modular and versatile, with available bore sizes from 40 to 200 mm and configurable operating strokes of up to 4000 mm. Each bore size can be equipped with up to three different piston rod diameters, allowing thrust and pulling forces to be precisely calibrated. The mounting options include ten configurations compliant with ISO standards: MP1, MP3, MS2, MT1, MT2, MT4, ME5, MP5, MX3 and MX5.
Stroke detection is managed by a high-precision electronic system. The transducer, designed for pressures of up to 35 MPa (350 bar), provides a resolution of 0.01 mm, independent linearity of ±0.05% and an operating speed of up to 2 m/sec. This component can be removed and replaced without dismantling the hydraulic cylinder, reducing machine downtime. Supported signals include analogue outputs (0/10 V and 4/20 mA) and the most widely used industrial digital protocols (SSI, CANopen, PROFIBUS-DP and IO-Link), with IP67 sealed connections and a 24 VDC power supply. The construction materials meet the highest strength standards: barrels and tie rods are made of high-strength steel, piston rods are made of chrome-plated steel or nickel and chrome-plated NI-CROMAX30, and advanced NBR seals incorporate low-friction PTFE or polyurethane elements for exceptional hydrodynamic efficiency. Production includes strict inspections and hydraulic and electronic testing performed on 100% of the units manufactured.
