Marine Tool Bearings are specialized components designed to withstand harsh marine environments, ensuring smooth operation and longevity. They are integral to mechanical systems in ships, reducing friction and supporting heavy loads. These bearings are typically corrosion-resistant and engineered for high performance in water-based applications.

Size: 20 mm to 500 mm inner diameter

Grade: ABEC 3 to ABEC 7 (or ISO P6 to P2)

Viscosity: ISO VG 68 to VG 220 (for lubricants)

Buoyancy: Neutral to slightly positive (depending on material and design)

Material: Stainless steel (AISI 440C), bronze, or polymer composites (PTFE, PEEK)

Load Capacity: 5 kN to 50 kN (dynamic)

Operating Temperature: -20°C to +120°C

Corrosion Resistance: High (marine-grade coatings or stainless steel)

Sealing: Double-lip seals or labyrinth seals for water ingress protection

Lubrication: Grease (NLGI 2) or oil bath

Speed Rating: 500 to 3000 RPM (depending on size and lubrication)
