Piston Hydraulic Cylinders MC Series

MC Series welded hydraulic cylinders are designed for a wide range of applications in mobile machinery and industrial equipment. Their compact and reliable welded construction allows easy integration into various machines and mechanisms. Hydraulic cylinders with the front head retained by a snap ring are designed for rated pressures up to 200 bar. Versions with a threaded front head can operate at rated pressures up to 250 bar.

Applications:

• agricultural machinery;
• municipal machinery;
• construction machinery;
• industrial equipment.

According to the applicable technical specifications (TU), Hydrosila products are not classified as dual-use products.

MC Series hydraulic cylinders feature a compact welded construction suitable for a wide range of mobile machinery and industrial equipment. The allowable working pressure depends on the front head design.

For agricultural hydraulic cylinders, the following options are available:

• reversing valve for reversible ploughs;
• end-of-stroke cushioning;
• adjustable pin-to-pin length;
• load-holding valves and other valves upon agreement with the customer.

For hydraulic cylinders intended for heavy-duty operating conditions, the following options are available:

• front heads with bolted flange mounting, designed to withstand significant peak loads;
• heat-treated rods for extended service life;
• special seals for operation under high peak pressures and in high-dust environments;
• end-of-stroke cushioning;
• load-holding valves and other valves upon agreement with the customer.

Standard MC Series hydraulic cylinders have the following specifications:

1. Materials

• rod — CK45 steel, chrome-plated surface, f7 tolerance, surface roughness Ra < 0.2 µm;
• minimum chrome coating thickness — 35 µm;
• rod corrosion resistance — 200 hours NSS in accordance with ISO 9227, rating 9 according to ISO 4540;
• chrome coating hardness — 900 HV;
• cylinder tube — seamless cold-drawn tube, internal surface roller-burnished to H9, Ra < 0.25 µm.

2. Seals

• rod — compact rod seal, wiper and guide elements;
• piston — compact five-piece seal designed for pressures up to 400 bar.

3. Marking

The marking on the cylinder body includes the hydraulic cylinder designation, serial number and date of manufacture.

4. Paint coating

Total coating thickness — not less than 80 µm. Corrosion resistance — not less than 240 hours in salt spray testing.

5. Testing

All hydraulic cylinders undergo acceptance testing with a safety factor of Ks = 1.5.

6. Packaging

Hydraulic cylinders are supplied in individual or group cardboard packaging depending on size.

Hydraulic fluids: mineral and special hydraulic oils with a kinematic viscosity of 30–70 mm²/s at +50 °C.

The fluids must comply with DIN 51524-2.
