Features include thrust collars, parallel or tapered bore and lubrication holes and grooves. This type of bearings feature high radial load capacity as the rollers and raceway are in linear contact. Our cylindrical bearings are equally suitable for heavy radial and impact loading.Cylindrical roller bearings are characterized by high radial-, and moderate thrust-load capacities. They contain cylindrically-shaped roller, which are nevertheless not true cylinders. Instead, they are crowned or end-relieved to reduce stress concentrations. This particular geometry results in low friction and allows high-speed applications. Cylindrical roller bearings are commonly available in precision grades such as RBEC-5, a classification from the Roller Bearing Engineers Committee (RBEC). RBEC ratings describe the accuracy and tolerance range of different types of bearings. As a rule, the higher the RBEC number, the tighter the bearing tolerances. Typically, cylindrical roller bearings are lubricated with oil, which also serves as a coolant.
