PROBLEM TO BE SOLVED: To suppress the increase of the temperature of a bearing and to prevent the occurrence of a damage, such as gall, by a method wherein a lubricant transfer part is located in the peripheral direction of a slide surface and a sufficient amount of lubricants are feedable. SOLUTION: Peripheral grooves 6c and 6d are recessed in the outside diameter and inside diameter surfaces 6a and 6b of a floating ring 6. A lubricant transfer part 8 is formed in a gap 7 formed between a peripheral groove 6d and an inner ring outside diameter surface 1a and a lubricant transfer part 8 is formed in a gap provided between a peripheral groove 6c and a holder inside diameter surface 5b, and lubrication states respectively therebetween are improved. |
