PROBLEM TO BE SOLVED: To provide a roller bearing with stud type cages easily assembled and disassembled. SOLUTION: Each annular cage 13 is provided with straight locking holes 31 bored in three parts at spaces of 120 deg., and the inner and outer annular cages 13 are connected by connecting pins 33 with both ends thereof pressed and rigidly fixed into the respective locking holes 31. The connecting pins 33 are formed of synthetic resin relatively low in flexural rigidity and relatively high in tensile rigidity. The inner and outer annular cages 13 are therefore allowed to have some relative angle displacement, while the separation and fall of cylindrical rollers 7 and the annular cages 13 are effectively prevented. The cylindrical rollers 7 and annular cages 13 are thereby sub-assembled without impeding the smooth operation of a bearing 1, and very easily fitted in and extracted from the bearing 1.
