Development of Light Weight Solid Lubricated Bearing Retainers.
Abstract
A materials development program was undertaken in an effort to develop a high strength-to-weight ratio self-lubricating composite for use as a solid lubricating retainer in ball bearings operating at speeds up to 60,000 rpm. The program encompassed a termpature range from -40 F to 1000 F. Functional tests using 204 and 205 size bearings were run at speeds up to 30,000 rpm and temperatures to 1000 F. Under these operating conditions, a maximum life of 3-1/2 hours was obtained on a 204 size bearing equipped with a Clevite 300 retainer. Attempts to employ light-weight, Teflon impregnated porous metal composites as self-lubricating retainers in high speed ball bearings were unsuccessful. No further testing of these particular materials is anticipated.
