Toyana bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling Toyana Bearings bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. 

High rigidity crossed roller bearings feature solid, one-piece construction for high accuracy. Inseparable design integrates inner and outer ring into one structure for high rigidity. Smooth rotation KOYO 501 Bearing ensured by separators incorporated between cylindrical rollers, suitable for high rotational speeds.
