In order to prevent rust of oil-free bearings, the surface to be pre-treatment, cleaning must be based on the surface of the rust-proof properties and conditions at the time, select the appropriate method. Commonly used solvent cleaning method, chemical treatment cleaning method and mechanical cleaning method.
Clean after cleaning can be used to dry compressed air drying, or with 120~170℃ dryer drying, can also be used to dry clean gauze. Also can be coated with anti-rust oil, Some small items are soaked in rust-proof grease, let its self-lubricating bearing surface adhesion of a layer of anti-rust grease Method. The thickness of the oil film can be achieved by controlling the temperature or viscosity of the antirust grease. For outdoor construction equipment or special shape products that do not apply to immersion or spraying, self-lubricating bearing should be careful not to accumulate when brushing, but also to prevent leakage of coating.
