Non-standard bearings with non-standard bearings, generally speaking, is the bearing does not meet the national standard dimensions, which all dimensions are different from standard bearings.

That is, non-standard bearings, generally speaking, is the bearing does not meet the national standard dimensions, that is, dimensions different from the national standards

All bearings.

Its main characteristics, low degree of versatility, application for special equipment, special occasions, in small batches, the newly developed equipment trials are in the majority, but because of its scale, the bulk of production, manufacturers and there are not many, costs are higher, more expensive.

Non-standard bearing Rust prevention methods

Editor

, Surface cleaning method:

1, surface cleaning: cleaning must be rust-proof nature and prevailing conditions of the surface, select the appropriate method. Common solvent cleaning, chemical cleaning and mechanical cleaning methods.
2, surface drying of drying available clean filtered compressed air drying, or using 120~170℃ dryer for drying, you can also use clean, dry gauze.
Second, coated with antirust oil method:
1, the immersion method: soak small items used in antirust oil, so its surface with a layer of antirust oil. Thickness of oil film antirust oil can be controlled by temperature or viscosity to achieve.
2, brushing method does not apply immersion or spray an outdoor construction equipment or special shape products, brush should not only pay attention when not accumulating, to guard against missing coating.
3, spray some large rust are not using immersion oil, generally with around 0.7Mpa pressure filtration of compressed air in air cleaning spray. Spray application of solvent-diluting oil or a thin layer of oil, but comprehensive fire prevention and protection measures must be used.
