According to domestic world famous excavator manufacturer requirement, we have started to use a new antirust oil to our slewing ring which produced for OEM.
This oil called hard coat antirust oil, it is a new type of antirust oil, The hard coat anti-rust oil has strong anti-rust ability and long service time.
Due to the high strength of the anti-rust film, this kind of oil has good stability and is not easy to remove. The hard coat oil not only overcomes the serious shortcomings of the anti-rust oil, such as the flow of the anti-rust oil and the adhesion of lime-sand, but also overcomes the difficulty of coating and removing the anti-rust grease.
Therefore, it is suitable for long-term storage and anti-rust on the surface of various metal products and occasions that need to be stored and transported in harsh environments.
The following picture is a sample we have finished hard coat antirust 2 years before, the antirust oil gave a good protection to our slew rings. If your machine worked in a bad enviroment, please feel free to contact us to inform us.
More than tha, we can do other antirust protection for our slew ring,like Galvanization, Spray painting, chromate treatment and so on.
