How to select the right precision/micro bearing for my equipment?

Selecting the right mini ball bearing starts with defining your core operating conditions and equipment needs. First, confirm the basic dimensions: bore size, outer diameter, and width to fit your shaft and housing. Next, identify the required precision grade (P0 to P5) based on your equipment’s rotation accuracy and noise requirements—higher precision (P5) suits motors and automation, while standard P0 works for general use. Then, determine the sealing type: ZZ metal shields for clean environments, or 2RS rubber seals for dust/water protection. Choose the appropriate clearance grade (CN/C3/C4) based on operating temperature and speed. Finally, match the material (GCR15 steel for standard use, stainless steel for corrosion resistance) and load capacity to your application’s radial and axial loads. If you are unsure, share your equipment specifications, and we can provide a tailored recommendation.
