| 摘要 |
The invention relates to a bearing having a rim-guided cage (4) comprising a bearing race (2) having a first guide surface (9) on a rim (8) and a cage (4) having a second guide surface (12) on a lateral surface (11) of the body (10) of the cage (4), wherein the two guide surfaces (9, 12) form a guide surface pair substantially having sliding contact and wherein a structuring (13) is disposed on one of the guide surfaces (9), receiving lubricant and releasing the same between the guide surfaces (9, 12), wherein the structuring (13) comprises a plurality of recesses (14; 26; 27; 32) spaced apart from each other and disposed in at least one of the two guide surface (9), and wherein a maximum extent of the recesses (14; 26; 27; 32) in the guide surface (9) is less than 100 µm, in particular less than 50 µm. Said bearing achieves the aim according to the invention of providing a bearing having a rim-guided cage reliably comprising improved wear and friction properties, even at a low level of lubricant. |
