Non-Standard Bearings Non-standard bearings that are non-standard bearings, popular speaking, is not in line with national standards for the size of the bearing, that is, the size of the national standard is different from all the bearings.
That is, non-standard bearings, popular speaking, that is not in line with national standards for the size of the bearing, that is, the size of the different from the national standard
Non-Standard Bearings The main features are low versatility, mostly special equipment, special occasions, small batch, new research and development equipment trial products accounted for the majority; but because of its non-scale, mass production, production enterprises and not much, the cost is high , The price is more expensive.
Prevention of rusty methods
Non-Standard Bearings First, the surface cleaning method:
1, surface cleaning: cleaning must be based on the nature of the surface of the rust and the conditions at that time, select the appropriate method. Commonly used solvent cleaning method, chemical treatment cleaning method and mechanical cleaning method.
2, the surface dry and clean can be filtered dry compressed air drying, or 120 ~ 170 ℃ dryer for drying, can also be dry with a dry gauze.
Second, the application of anti-rust oil method:
1, soaking method: some small items soaked in rust-proof grease, so that the surface adhesion of a layer of anti-rust grease method. Oil film thickness can be achieved by controlling the temperature or viscosity of the rust-proof grease.
2, brushing method is not suitable for immersion or spraying of outdoor construction equipment or special shape of the product, brush should not only pay attention to the accumulation, but also to prevent leakage coating.
3, spray a number of large-scale anti-rust can not use the soaking method of oil, generally with about 0.7Mpa pressure filter compressed air in the air cleaning place for spraying. Spray method for solvent dilution type anti-rust oil or thin layer of anti-rust oil, but must be used to improve the fire and labor protection measures.
