The 6303 series bearings have envelope dimensions of 17x47x14 and the 6304 series bearings have envelope dimensions of 20x52x15. The 6300 Series is considered a “medium” duty bearing. The 6300 Series is made to withstand greater radial and thrust load capacities. These bearings are available in sealed or shielded configurations. In order to determine the configuration that’s right for your application consider this information: rubber seals (2RS) are more likely used in applications in which the atmosphere is “dirtier” and the speed is not the primary concern. On the other hand, metal shields (ZZ), are better for applications where speed is the 1st priority and the environment is relatively clean. Looking for RS and Z Series? These bearings are enclosed (ZZ or 2RS) on both sides. However, some manufacturers, for example, stamp 6303 RS or 6303 Z, on BOTH sides of the bearing, therefore making the complete part number 6303 2RS and 6303 ZZ, respectively. However, if your bearing only has 1 side enclosed, then you will in fact need a 6303-RS or a 6303-Z . Please contact us at 305-573-9855 to place an order for these type of bearings. return to top
