  • Method of forming a lubricating film on a linear motion ball bearing
    Patent number: 6240641
    Abstract: A process for forming a lubricating film on a direct acting bearing includes the steps of forming a liquid film on at least the rolling and sliding portions of the direct acting bearing by using a solution prepared by diluting a fluorine-containing polymer in a solvent. The liquid film is then cured to form a solid film of a fluorine-containing polyurethane high molecular compound on the direct acting bearing.

  • Bearing and a method for mounting them in screw compressor
    Patent number: 5722163
    Abstract: Rolling element bearings capable of both axial and radial restraint are readily removably mounted on the shaft of each screw rotor so as to allow a clearance type radial fit between the bearing and shaft. A washer engages the inner race of the bearing which also engages a shim. A bolt squeezes the inner race between the washer and shim to secure the bearing in place while the shim thickness/height determines the position of the rotor within the casing.
