Hydraulic Rotary Coupling Bearings enable seamless fluid transfer between stationary and rotating components in hydraulic systems. They ensure minimal leakage and high efficiency in dynamic applications. These bearings are crucial for maintaining continuous hydraulic power transmission in rotating machinery.

Hydraulic Rotary Coupling Bearings:
- Size Range: 50 mm to 500 mm inner diameter
- Material: Stainless steel (AISI 304/316), carbon steel, or bronze
- Pressure Rating: Up to 350 bar (5,000 psi)
- Temperature Range: -20°C to +120°C
- Viscosity Compatibility: ISO VG 32 to VG 68 hydraulic oils
- Buoyancy: Neutral or slight positive buoyancy depending on seal design
- Grade: DIN/ISO standards compliant (e.g., DIN 3761)

Hydraulic Systems:
- Operating Pressure: 100 to 700 bar (1,500 to 10,000 psi)
- Fluid Viscosity: ISO VG 15 to VG 150 (depending on application)
- Material: Carbon steel, stainless steel, or aluminum for components
- Temperature Range: -40°C to +200°C (with specialized seals)
- Flow Rate: 5 to 500 L/min (system-dependent)
- Buoyancy: Not typically applicable unless subsea systems are used
- Grade: ISO 4406 cleanliness standards (e.g., 18/16/13)
