A wide width inner wheel type deep groove bearing is provided to assemble without a separate step ring simply when applying to tools including a wheel or a conveyer roller and prevent the side of an outer wheel from being rubbed or contacted with a case. A wide width inner wheel type deep groove bearing comprises an inner wheel(2), an outer wheel(3), a step ring(6) and a case(7). The deep groove bearing is fixed in the case by forming the width of the inner wheel wider than the width of the outer wheel. When bearing is rotated, the available space is secured between the outer wheel and the case due to the inner wheel having broad width. |
