<P>PROBLEM TO BE SOLVED: To provide a durable spherical bearing hard to damage a projecting spherical body of an inner holder thereof even if the inner holder is brought in contact with a polytetra fluoroethylene group liner over a long time. <P>SOLUTION: This spherical bearing is formed of an outer holder 1 formed with a recessed spherical sliding surface having the polytetra fluoroethylene group liner in the inner peripheral surface of a race and the inner holder 3 held by the outer holder and having a projecting spherical peripheral surface to be slid with the sliding surface of the outer holder. The projecting spherical sliding surface of the inner holder has an even thin film layer 4 of TiAIN compound. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
