Document Type and Number:
Japanese Patent JP2791924
Kind Code:
B2
Abstract:
A short cylindrical and thin sleeve bearing including a radial bearing portion of a dynamic pressure type on which grooves are formed is worked with high accuracy. Grooves are formed on an inner peripheral surface of a blank by a groove forming tool. Raised deformations generated on the inner peripheral surface as a result of this groove forming are removed by ball sizing of passing a steel ball on the inner peripheral surface. Further, by a roller burnishing tool, the cylindrical bore of the bearing is finished to have a predetermined diameter, and simultaneously, specular finish of the inner peripheral surface is effected.
