Not to scale.
(*) The chamfer dimensions are minimum values.
Suffix C represents medium-angle tapered roller bearings. Since they are designed for specific applications, please consult NSK when using bearings with suffix C.
The bore diameter "no-go side" tolerances (High) specified in this drawing do not necessarily apply within a distance from the ring face to 1.2 times the chamfer dimension r (max).
Some of these tolerances conform to NSK standards.
