Engine piston rod bearings are crucial components that reduce friction between the piston rod and crankshaft in marine engines. These bearings ensure smooth operation and longevity by providing a durable, low-friction surface. Marine engine spares like these are essential for maintenance and repair to prevent engine failure.

Size: Varies (typically 50mm to 500mm inner diameter)

Grade: SAE 841, SAE 15, or equivalent marine-grade standards

Viscosity: ISO VG 68 to VG 150 (depending on engine requirements)

Buoyancy: Not applicable (solid metal component)

Material: Steel-backed with white metal (Babbitt) overlay, aluminum-tin alloys, or copper-lead alloys

Load Capacity: High (designed for dynamic and static loads in marine engines)

Operating Temperature: -20°C to 150°C (varies by engine design)

Surface Finish: Precision machined (Ra 0.4 to 0.8 μm)

Corrosion Resistance: High (marine-grade coatings or materials)

Lubrication: Hydrodynamic lubrication (oil film critical for operation)

Yes, Engine Piston Rod Bearings and Marine Engine Spares typically comply with maritime standards such as ISO 9001, ISO 14001, and classification society standards like ABS, DNV, or Lloyd's Register.
