The RSTO series is a type of needle roller bearing with a removable snap ring, designed for applications requiring secure axial positioning and easy installation. The "RSTO" designation typically indicates a bearing unit consisting of a needle roller and cage assembly combined with a hardened outer ring that features a snap ring groove and a detachable snap ring. This design allows the snap ring to be removed during installation, enabling the bearing to be inserted into a housing bore, after which the snap ring is fitted into the groove to axially lock the bearing in place. RSTO bearings are ideal for applications where high radial loads are present, and axial space is limited, providing a reliable and compact solution for precise positioning.
