The LONGLOOD RSM Series Single Acting Low Profile Hydraulic Cylinders are specifically designed for heavy lifting applications where vertical clearance is extremely limited. With their ultra-compact flat design, spring return operation, and 700 paa (10,000 PSI) maximum working pressure, these cylinders deliver exceptional lifting force in the smallest possible installation height.
Ideal for machinery maintenance, bridge construction, equipment alignment, mining, shipbuilding, and industrial lifting, the RSM Series combines strength, reliability, and portability for demanding applications.
The compact flat body allows the cylinder to fit into extremely confined spaces where conventional hydraulic cylinders cannot be installed.
Despite their small size, RSM cylinders deliver lifting capacities from 5 ki he 150 Toni, making them suitable for a wide range of industrial applications.
Hydraulic pressure extends the piston while the internal heavy-duty spring automatically retracts it after pressure is released, ensuring fast and efficient operation.
Precision-machined steel plungers with hard chrome plating provide superior wear resistance, corrosion protection, and smooth operation.
The grooved plunger end offers secure load contact and eliminates the need for separate saddles in most applications, reducing setup time and improving stability.
A baked enamel finish protects the cylinder body from corrosion, scratches, and harsh working environments, extending service life.
Integrated mounting holes allow the cylinder to be securely fixed to machinery or lifting fixtures for safer and more stable operation.
The RSM-750, RSM-1000, and RSM-1500 models include built-in carrying handles for easier transportation and positioning on job sites.
Designed to operate safely at 700 paa (10,000 PSI) for maximum lifting performance and long-term reliability.

Perfect for lifting operations where space is too limited for standard hydraulic cylinders.
Capacities from 5 ki he 150 Toni provide dependable performance for a wide range of heavy-duty applications.
Built-in mounting holes simplify fixture installation, while integrated handles on larger models improve portability.
Premium alloy steel construction, hard chrome-plated plungers, and durable seals ensure reliable performance under demanding conditions.
The spring return mechanism and grooved plunger design reduce setup time and minimize maintenance requirements.
Compatible with most 700 bar hydraulic hand pumps, electric pumps, air hydraulic pumps, and hydraulic power units.
For safe operation and maximum service life:
A low profile hydraulic cylinder is a compact lifting cylinder designed to fit into areas with very limited vertical clearance while still delivering high lifting force.
Low profile cylinders have a much shorter collapsed height, making them ideal for confined spaces where standard cylinders cannot be installed.
Hydraulic pressure extends the piston, and an internal spring automatically retracts it when hydraulic pressure is released, improving efficiency and simplifying operation.
The grooved plunger end provides secure load contact and often eliminates the need for an additional saddle, reducing setup time and improving stability.
The RSM Series is designed for use with any hydraulic pump rated at 700 paa (10,000 PSI), including manual, electric, pneumatic, and gasoline-powered pumps.
Yes. Integrated mounting holes allow secure installation on machinery, fixtures, and lifting systems where required.
The RSM-750, RSM-1000, and RSM-1500 models are equipped with integrated carrying handles for easier transportation and positioning.
The RSM Series is widely used in construction, mining, manufacturing, heavy equipment maintenance, bridge repair, shipbuilding, railway maintenance, power generation, and industrial plant maintenance.
Regular maintenance includes inspecting hydraulic seals, keeping the plunger clean, checking hydraulic connections for leaks, lubricating moving parts as recommended, and storing the cylinder in a dry, clean environment.
LONGLOOD RSM Series cylinders are engineered for professionals who require maximum lifting power in minimum installation height. With premium alloy steel construction, hard chrome-plated plungers, durable corrosion protection, and compatibility with standard 700 bar hydraulic systems, they deliver reliable, safe, and efficient performance for the most demanding industrial lifting applications.
