TRACK ROLLERS STO 10 NBS
RSTO and STO, are able to mount outer rings, inner rings and
cage in a separate way and seen that they are not a sole group,
they can reach very high rotation speeds and for this reason
have to be oil lubricated.
The original lubricant must be compatible with the future one.
Outer ring and needle roller cage have to be axially guided.
