摘要： PROBLEM TO BE SOLVED: To reduce abrasion and to prevent early seizure by reducing slide friction resistance of a guide surface of a retainer relative to a planetary gear and an inner peripheral surface of a planetary roller.
SOLUTION: In the retainer 7 for the roller bearing 6, a cured layer 7c by heat curing treatment such as cementation is formed on a side of at least guide surface of a matrix material 7a comprising a steel material. A surface of the cured layer 7c is cleaned such that an oxide layer does not exist. A hard film of high hardness such as a DLC film 9 is coated on the cleaned surface. Further, a soft film having solid lubrication effect such as an Ag film 10 is coated on a surface of the hard film.

摘要： PROBLEM TO BE SOLVED: To provide a rolling bearing 1 in which at least either one of an outer ring 2 and an inner ring 3 is made of ceramics, and an axial end in an opposing angular space between the outer ring 2 and the inner ring 3 is sealed without using a seal member, thereby reducing cost. SOLUTION: An annular recess 2b is provided at one shoulder section on an inner circumferential surface of the outer ring 2 made of ceramics. An opposing annular projection 5d is provided on a holder 5 with a predetermined clearance from the annular recess 2b. Because the clearance formed at an opposing section between the annular recess 2b and the annular projection 5d forms a non-contact seal section (labyrinth seal), a conventional seal member becomes unnecessary.

SOLUTION: A cone roller bearing 1 as this rolling device includes a cone roller 4. The large diameter side end face 4c of the cone roller 4 has an annular surface 4f as a rolling slide part in a sliding contact with the collar part 7 of an inner ring 3. A treated region 9 where chemical polishing treatment as an oxide removing treatment is performed, is formed on the entire surface of the cone roller 4. The hard film 11 is formed on the front surface of the region 10 including the annular surface 4f as the rolling slide part of the part of the treated region 9. The hard film 11 preferably includes a diamond-like carbon film.
