    Abstract: PURPOSE:To improve lubricating property, extend a service life and suppress heat generation by melting and removing glass fibers on the machined surface part of a bearing retainer made of a self-lubricating type material reinforced by adding glass fibers. CONSTITUTION:A partially processed material of a short cylindrical shape is formed with a glass fiber reinforced PTFE compound material formed by impregnating the PTFE having self-lubricating property into glass-woven cloth. Its outer circumference is then ground to a specified diameter and a number of pocket holes 2 are machined on its peripheral surface to form a bearing retainer 1. The bearing retainer 1 is then immersed in hydrofluoric acid to melt and remove glass fibers to a depth of PTFE layer necessary for working as a lubricant. Accordingly, since the glass fibers are not exposed on the surfaces of the pocket holes 2 down to an appropriate depth, lubricating property is improved, life is extended and heat generation is suppressed.

    Abstract: PURPOSE:To obtain a roller bearing fit for use under severe ambience like high vacuum and cryogenic condition by composing a roller bearing cage with tetrafluoroethelene resin. CONSTITUTION:A bearing cage is composed of tetrafluoroethelene resin containing at least calcium fluoride or calcium oxide. A bearing incorporating this roller bearing cage requires less operating torque in a condition where no lubricant is supplied, and the amount of wear of the cage itself becomes lesser so that a stabilized operation is assured under severe ambience.

    Abstract: PURPOSE:To prevent separation of solid lubricant from organic material by forming a retainer by means of alternately laminating a solid lubricant impregnated organic material layer and a cloth-layer. CONSTITUTION:A cloth 7' impregnated with organic material like plastics, etc. and a sheet 8 made of organic material like plastics, etc. impregnated with molybdeniumdisulfide, graphite, etc. are wrapped alternately around a spindle 9' in a multilayer form until the desired thickness is achieved. While wrapping or after wrapping, both the cloth 7' and the sheet 8 are heated and pressurized together to become an integral construction. An obtained cylindrical laminated body is cut off vertically to the spindle at the desired intervals and then a retainer 4' can be formed by drilling pockets supporting balls in each cut-laminated body.
