Deep groove ball bearings rust rust usually between division and finished rust.

Rust between workers belonging to the processing inter-process rust, usually 3-30 days. It will generally be water-based rust inhibitor. Advantages of water-based rust inhibitor is a simple operation and low cost. And rust, does not require degreasing cleaning.

Finished generally refers to rust rust deep groove ball bearings after storage or delivery before assembly, usually in a month - 2 years or so. The general use of oil or apply anti-rust VCI rust-proof paper packaging. VCI rust-proof paper packaging advantages are good rust, before assembly, no-clean, simple, environmentally friendly energy.

VCI rust-proof paper will always release a small amount of rust inhibitor (VCI definition: volatile corrosion inhibitor). After this paper packaging, will form a protective layer of gas in the package, can be reliably suppressed deep groove ball bearings corrosion. VCI rust-proof paper are rusting in direct contact with the bearing and distance; bearing packaging rust VCI rust-proof paper, rust-proof up to 3 years; bearing packaging rust VCI rust-proof membrane, rust-proof up to 1 year. This is the most used product HRB Harbin, now commonly used plastic barrels rust process.
