Bearings anti-rust is a crucial task, especially between processes. After bearings undergo acid washing, cleaning, and grinding in the heat treatment workshop, there are still several more processes. When products are not produced in a continuous flow, after each process is completed, they are stored in a turnover warehouse. At this point, the anti-rust treatment must be applied to the bearing rings stored between processes to ensure product quality.

Bearings must be thoroughly cleaned before applying rust-proof oil. The surface must be free of any dirt, sweat stains, etc., prior to applying the rust-proof oil.

The incorrect anti-rust oil used, or the poor quality of the anti-rust oil itself, Nantong Yongyu Antirust Material Co., Ltd. uses imported rust inhibitors for its anti-rust oil, which offers superior rust prevention.

Inadequate rust-preventive oil coating; some areas of the bearings may not have been coated with rust-preventive oil or may be unevenly applied.

The rust-preventing oil tank was not replaced in a timely manner or new bearing rust-preventing oil was not added.

Poor packaging, and the application of rust-proof oil on the bearings requires strict standards for the storage and packaging materials.

Sealed packaging of finished bearings with anti-rust oil, utilizing "Yongyu" brand VCI vapor phase corrosion inhibitors, can prevent rust and mildew spots caused by atmospheric environment during storage and transportation, thus ensuring the use performance.
