Features: Flat design for small spaces, spring retraction, wear resistance, corrosion resistance, more than 50 tons with handle.
Uses: Widely used in maintenance, lifting operations, welding and positioning of structural parts, assembly, flange separation and other places.
Ultra low height hydraulic cylinder is widely used in synchronous lifting to replace the rubber bearing for bridge maintenance, synchronous lifting for large equipment maintenance, welding positioning of structural parts, assembly of equipment, piping flange tray separation and other application occasions, spring return design applys to place with a high degree of closure and maximum stroke is the primary factor.
● Compact, flat design for where other cylinders will not fit
● KET-RSM-750, 1000 and 1500 have handles for easy carrying
● Mounting holes permit easy fixturing
● High strength alloy steel for durability
● Single acting, spring return
● Hard chrome plated high-quality steel plungers
● Plunger wiper reduces contamination, extending cylinder life
● Baked enamel finish for increased corrosion resistance
● 3/8 “- 18NPT coupler and dust cap included on all models
Ultra-Thin Hydraulic Cylinder Paired with KET-P-392 Manual Pump
● Advantage: Requires minimal manual effort to achieve significant power output.
5-ton Ultra-Thin Hydraulic Cylinder with Throttle Valve
● A throttle valve can be added to the ultra-thin hydraulic cylinders to close the oil circuit when it reaches its full stroke, allowing it to maintain its lifted position.
Multi-Unit Ultra-Thin Hydraulic Cylinder Synchronous Lifting System
● For the synchronous lifting of multiple ultra-thin hydraulic cylinders, you can opt for a pulse width controlled synchronous lifting system. This system allows for simultaneous lifting across all points with an error margin of ≤0.5mm. It is commonly used for bridge construction and the synchronous lifting of large-scale equipment for maintenance.
● For higher lifting capacities (300 tons, 500 tons, or more), please choose our electric hydraulic cylinders.
● For long-term support with a self-locking feature, please select our self-locking jacks
● For a lower body height and a larger working stroke, please consider our low profile hydraulic cylinders
