The normal operation of bearings is inseparable from effective lubrication, but the harm of water to bearings may not be valued by everyone. In fact, water has a great impact on the service life of bearings. With only a small amount of water (close to 500ppm), the service life of rolling bearings wi...

Beryllium oxide: beryllium oxide not only loses a lot of steel, but also reduces the surface quality of forgings and the service life of forging dies. If pressed into the metal, forgings will be scrapped. Failure to remove beryllium oxide will affect machining.Decarburization: decarburization refers...

1. Cold plastic deformation layer: in the grinding process, each moment of abrasive grain is equivalent to a cutting edge. However, in many cases, the rake angle of the cutting edge is negative. In addition to the cutting effect, the abrasive particles make the workpiece surface bear the extrusion e...

The hygienic design of food machinery plays an important role in controlling food safety. However, if the sanitary design of equipment parts is not considered, but only the general application of this concept, there may be a risk of bacterial breeding and transmission in the bearing, said Davide Zan...

What role can lubricating oil play in bearing maintenance? What is the connection with bearing maintenance?The first is the movement speed: the higher the speed, the easier it is to form an oil wedge. Low viscosity lubricating oil can be selected to ensure the existence of oil film. If the viscosity...
