Deep groove ball bearings 40 x 52 x 7 mm
8 part numbersSee all deep groove ball bearings →
They are all the same bearing type: deep groove ball bearings (8 part numbers, series 618).
4 of the 8 part numbers are the basic designation alone, without a suffix. The most frequent suffixes, with the number of part numbers they appear in: 2RS1 (1), 2RSR (1), 2RZ (1), and 2Z (1).
These are boundary dimensions according to ISO 15, in millimetres: d is the bore, D the outside diameter and B the width.
Two bearings with the same size are not necessarily the same bearing: the type, the seals or shields, the internal clearance, the cage and the load rating depend on the designation, the suffix and the brand. That is why we quote by part number: send us the full part number shown on the bearing, the box or the drawing, or the size together with the variant you need.
If the part number can no longer be read, measure the bore, the outside diameter and the width, and look the size up in the bearings-by-size index: each size has its own page with all its part numbers.
