Methods to prevent the rust of oil-free bearings

What are oil free bearings

Machinery and equipment in order to solve the high temperature, low-speed, heavy, dusty, water, shower and shock and vibration of the lubrication problem, use oil-free self-lubricating bearings.

Oil free bearings are a self-lubricating, maintenance free bearing and are a perfect solution to projects

High quality self-lubricating bearing

Oil-free bearings will cause rust and other phenomena because of the different environment they are in.If the bearing rusts, it will affect the normal operation of the self-lubricating bearing and cause unnecessary losses.So, how to prevent oil-free bearing rust?

How to prevent the rust of oil-free bearings

In order to prevent the rust of oil-free bearings, the surface should be pretreated. The appropriate method must be selected according to the nature of the antirust surface and the conditions at that time.The commonly used solvent cleaning method, chemical treatment cleaning method and mechanical cleaning method.After cleaning, dry compressed filtered air can be used to dry, or dried with a dryer of 120~170℃, or dried with clean gauze.

 

In addition, it can also be coated with antirust oil. Some small items are soaked in antirust oil and adhered to a layer of antirust oil on the surface of self-lubricating bearings.Oil film thickness can be achieved by controlling the temperature or viscosity of the antirust grease.For outdoor construction equipment or special shaped products that are not suitable for soaking or spraying, attention should be paid to not only avoid accumulation but also prevent leakage of coating when brushing the self-lubricating bearing.

 

Some large antirust can not be soaked in oil, generally with about 0.7Mpa pressure of filtered compressed air in clean air for spraying.Spray method is applicable to solvent diluent antirust oil or thin layer antirust oil, but must adopt perfect self-lubricating bearing fire protection and labor protection measures.It is necessary to do a good job in preventing the rust of oil-free bearings.
