When removing a bearing surface for maintenance, applying rust preventive oil is essential to protect the surface from corrosion and rust during the maintenance process. Bearings are typically composed of metal materials that can tarnish or corrode when exposed to moisture and environmental conditions. Rust preventive oil creates a protective barrier against such elements, helping to ensure that the bearing and surrounding components remain in good condition while maintenance is underway.

This oil is specifically formulated to provide long-term protection against rust and is suitable for metal surfaces that may be exposed to air or moisture. It mitigates the risk of pitting or degradation that can occur during disassembly and storage, which is crucial for the reliability and longevity of the bearing.

Utilizing water-based lubricants may not provide sufficient protection against rust, as they might evaporate or wash away, leaving the metal vulnerable. An anti-seize compound is typically used during reassembly to prevent galling and seize-up but is not ideal during disassembly. General-purpose grease might be too thick and not suitable for application on metal surfaces that require cleaning for maintenance. Hence, rust preventive oil is the most appropriate choice for maintaining the integrity of the bearing surface during removal.
