The SR series inch-size stainless steel bearings are a type of deep groove ball bearing. The “S” stands for stainless steel material. In this R series, the open-type and sealed-type bearings have different widths (heights), while the outer and inner diameters remain the same.
For small-size matching, use this chart together with CXE Bearing collections for stainless miniature ball bearings, metric ball bearings, and stainless steel bearings; those pages provide a cleaner path from dimensions to related products.
All ZZ shielded bearings can also be made with 2RS rubber seals.
d represents the inner diameter of the bearing, D represents the outer diameter, and B represents the width (height) of the bearing. ZZ indicates that the bearing has metal shields, while 2RS indicates rubber seals. The rubber seals used in CXE Bearing are all RoHs compliant.
