At this year’s Hannover Messe in Germany, bearing manufacturer NKE Austria GmbH presents bearings with black oxide finish. The protective layer improves run-in and wear characteristics and protects against environmental effects. Especially in critical applications such as wind turbine gear boxes, b... read more
Grease is discolored in the bearing, and it will change color even if it is not placed in the bearing. This is because: First, there is an oxidation problem with the grease. When the grease is placed (or operated) for a period of time, it will have a lot of contact with oxygen, and at the same time,... read more
Bearing is a component that fixes, rotates, and reduces the coefficient of friction of the load during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, the mechanism for reducing the friction coefficient during the transmission of the movin... read more
