Abstract:
A cylindrical roller bearing includes a retainer having first anti-separation portions for preventing separation of first cylindrical rollers from respective pockets of the retainer, and second anti-separation portions for preventing separation of second cylindrical rollers from the respective pockets. The axial distance between each first anti-separation portion and the corresponding second anti-separation portion is larger than the lengths of the first cylindrical rollers or the second cylindrical rollers so that one of the two cylindrical rollers which is to be first inserted into each pocket does not have to be pushed into the pocket.

Claim (Index 1):
A cylindrical roller bearing comprising;\n first cylindrical rollers; second cylindrical rollers; and a one-piece retainer formed with pockets circumferentially arranged at predetermined intervals, wherein each of the first cylindrical rollers and each of the second cylindrical rollers are received in a respective one of the pockets so as to be axially aligned with each other, wherein the retainer includes:\n crossbars that separate respective circumferentially adjacent pairs of the pockets from each other; \n pairs of end surface portions, each pair of the end surface portions being on respective sides of, and defining an axial width of, a respective one of the pockets; \n first anti-separation portions configured to prevent separation of the first cylindrical rollers from the respective pockets; and \n second anti-separation portions configured to prevent separation of second cylindrical rollers from the respective pockets, \n wherein an axial distance between each of the first anti-separation portions and a corresponding one of the second anti-separation portions is larger than one of a length of a corresponding one of the first cylindrical rollers and a length of a corresponding one of the second cylindrical rollers.
