Patent number: 10024362Abstract: In order to make a bearing, such as a roller bearing, insensitive to a lack of maintenance lubrication or irregular maintenance lubrication while at the same time retaining its mechanical performance, at least one bearing part of the bearing is provided at least partially with an oleophilic adhesion promoter layer. The adhesion promoter layer binds a lubricant layer of the bearing to the bearing part provided with the adhesion promoter layer. The adhesion promoter layer is bonded to an elemental-iron-free surface of a bearing part body. The removal of free iron from the bearing part body surface is carried out with nitric acid, chromate solution and/or citric acid. The treated bearing part has an oleophilic anti-corrosion adhesion promoter layer. The bearing may be used in pressure-operated devices, in particular in turbine handpieces used by dentists, because the loss of the lubricant layer during operation of the device was particularly high.Type: GrantFiled: April 13, 2017Date of Patent: July 17, 2018Assignee: GRW GEBR.
