Rudder Horn Bearing Seal Installation Sleeves are specialized tools used in steering systems to facilitate the precise installation of seals. They ensure proper alignment and prevent damage to the seal during assembly. These sleeves are critical for maintaining the integrity and longevity of rudder horn bearings.

Size: Typically ranges from 50mm to 300mm in diameter, depending on vessel requirements.

Grade: High-grade stainless steel (316L or equivalent) or bronze for corrosion resistance.

Viscosity: Compatible with lubricants of ISO VG 68 to VG 150 viscosity grades.

Buoyancy: Neutral buoyancy in seawater, designed to minimize hydrodynamic drag.

Material: Stainless steel, bronze, or composite polymers for wear resistance and durability.

Seal Type: Lip seals or mechanical seals, often made of nitrile rubber (NBR) or polyurethane (PU).

Operating Temperature: -20°C to +80°C (-4°F to +176°F).

Pressure Rating: Up to 10 bar (145 psi) for standard applications.

Surface Finish: Smooth (Ra ≤ 0.8 μm) to reduce friction and wear.

Corrosion Resistance: Meets ASTM B117 salt spray testing standards.

Load Capacity: Designed for radial loads up to 5 kN (1124 lbf).

Installation Method: Press-fit or adhesive bonding, depending on sleeve design.
