SF-1X
Properties
The SF-1X bearings are encapsulated sliding bearings made of a three-layer composite produced from a steel strip, a sintered-on porous bronze layer and a surface sliding layer made of PTFE and Pb (lead). This type of bushing has a low friction coefficient and protection against wear and corrosion, and can be used without oil. The low manufacturing costs and top-of-the-range technical foundations mean that these bushings are used in a variety of different kinds of sliding applications, such as in textile manufacturing machinery, hydraulic systems and automotive machinery as well as agricultural and forestry machinery.
