PURPOSE:To provide a low cost corrosion resitant rolling bearing having long life wherein lubricating oil can be automatically supplied for long periods, and the generation of rust is restrained even in the corrosive atmosphere such as in water. CONSTITUTION:Lubricating oil contained polymer 15 is filled in the space sandwiched between an outer race 11 and an inner race 12 made of corrosion resistant materials and shutted off from outside. The lubricating oil contained polymer 15 includes one or plural polymers to be selected from the different kinds of polymer groups having the basically same chemical constitution, and the sum of the content of polymer in the lubricating oil contained polymer 15 is 5 to 90 weight %, while the lest part is lubricating oil. Lubricating oil seeps gradually with time and is uniformly supplied to the contact surface of a bearing washer and a rolling element 13 in every nook and cranny. |
