As the leading ship supplier in Ross Dependency, Propeller Shaft Alignment Dial Indicators, we specialize in delivering high-quality Thrust Bearing Shim Adjustment with unmatched speed and reliability. Trusted by shipowners and masters worldwide, our team ensures your vessel gets everything it needs — on time, every time.
Thrust bearing shim adjustment in marine propulsion involves fine-tuning the axial clearance of the thrust bearing to ensure proper load distribution and alignment. Shim thickness is adjusted to maintain optimal bearing performance and prevent excessive wear or misalignment. This process is critical for efficient power transmission and longevity of propulsion systems.
Size: Typically ranges from 0.05 mm to 5 mm in thickness, custom sizes available based on propulsion system requirements.
Grade: High-grade precision shims, often compliant with ISO 9001 or marine classification society standards (e.g., ABS, DNV).
Viscosity: N/A (shims are solid components; lubrication viscosity depends on adjacent bearing oil, typically ISO VG 68-100 for marine applications).
Buoyancy: Negligible (shims are non-buoyant metallic or composite components).
Material: Carbon steel, stainless steel (AISI 316), or bronze; corrosion-resistant coatings (e.g., zinc, cadmium) for marine environments.
Hardness: 200-400 HB (material-dependent); ensures wear resistance under thrust loads.
Surface Finish: 0.8-1.6 μm Ra to minimize friction and ensure even load distribution.
Operating Temperature: -20°C to +150°C (material-specific; higher grades may tolerate extremes).
Load Capacity: Designed for axial thrust loads up to 50 kN/cm² (varies with thickness and material).
Corrosion Resistance: Essential for saltwater exposure; materials/coatings selected per ASTM or marine standards.
