This bearing series has envelope dimensions of 17x40x11/16. The 5203 series is a double row bearing which meets the demand for increased axial and radial rigidity where the application design limits space. The “ZZ” and “2RS” suffix refers to the material protecting the rolling elements. The “ZZ” refers to the bearings metal shield and the “2RS” refers to the rubber seals. In most cases, shielded bearings are more practical in cleaner, high-speed applications, while the sealed bearings are more practical for applications of slower speeds and dirtier environments. This bearing type accommodates a thrust load from either direction. They are of course wider than a single row bearing and perform almost as if two bearings had been installed together.

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.
