Features of STO Support Rollers
STO Series Support rollers, without flange rings, with an inner ring .
RSTO Series Support rollers, without flange rings, with an inner ring .
The STO type has an inner ring, and the inner and outer rings and their matching needle roller cage assemblies can be installed separately.
The support roller RSTO type does not have an inner ring, and the support roller can run directly on the hardened shaft as the raceway.
Since RSTO and STO type support rollers do not have ribs and end face retaining rings, they must be axially guided during installation, and their guiding surfaces must be at least precision machined.
