RSM Series Features

Ultra-Low Profile Flat Design

The compact flat body allows the cylinder to fit into extremely confined spaces where conventional hydraulic cylinders cannot be installed.

Powerful Lifting Capacity

Despite their small size, RSM cylinders deliver lifting capacities from 5 a 150 toneladas, making them suitable for a wide range of industrial applications.

Single-Acting Spring Return

Hydraulic pressure extends the piston while the internal heavy-duty spring automatically retracts it after pressure is released, ensuring fast and efficient operation.

Émbolo de aceiro cromado duro

Precision-machined steel plungers with hard chrome plating provide superior wear resistance, protección anticorrosiva, e un funcionamento suave.

Extremo do émbolo ranurado

The grooved plunger end offers secure load contact and eliminates the need for separate saddles in most applications, reducing setup time and improving stability.

Durable Corrosion Protection

A baked enamel finish protects the cylinder body from corrosion, arañazos, and harsh working environments, extending service life.

Convenient Mounting Holes

Integrated mounting holes allow the cylinder to be securely fixed to machinery or lifting fixtures for safer and more stable operation.

Integrated Carrying Handles

O RSM-750, RSM-1000, and RSM-1500 models include built-in carrying handles for easier transportation and positioning on job sites.

700 Bar Maximum Working Pressure

Designed to operate safely at 700 bar (10,000 PSI) for maximum lifting performance and long-term reliability.

• Clean the plunger before storage to prevent contamination and corrosion.

Preguntas frecuentes (Preguntas frecuentes)

1. What is a low profile hydraulic cylinder?

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.

2. What is the difference between a low profile cylinder and a standard hydraulic cylinder?

Low profile cylinders have a much shorter collapsed height, making them ideal for confined spaces where standard cylinders cannot be installed.

3. How does the spring return system work?

Hydraulic pressure extends the piston, and an internal spring automatically retracts it when hydraulic pressure is released, improving efficiency and simplifying operation.

4. Why does the RSM Series use a grooved plunger?

The grooved plunger end provides secure load contact and often eliminates the need for an additional saddle, reducing setup time and improving stability.

5. Which hydraulic pump is compatible with the RSM Series?

The RSM Series is designed for use with any hydraulic pump rated at 700 bar (10,000 PSI), including manual, eléctrico, pneumatic, and gasoline-powered pumps.

6. Can these cylinders be permanently mounted?

Si. Integrated mounting holes allow secure installation on machinery, fixtures, and lifting systems where required.

7. Which models include carrying handles?

O RSM-750, RSM-1000, e RSM-1500 models are equipped with integrated carrying handles for easier transportation and positioning.

8. What industries commonly use RSM hydraulic cylinders?

The RSM Series is widely used in construction, minería, fabricación, mantemento de equipos pesados, bridge repair, construción naval, mantemento ferroviario, xeración de enerxía, and industrial plant maintenance.

9. How should the cylinder be maintained?

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.
