High speed electric motors, tape guides,
radial and axial loading. |
|
| Note that the final radial play after assembly is the important operating condition,
therefore, compensation for interference must be made in the bearing
specification. See section on mounting and
fitting.
Contact SWC directly for information on
non-standard radial play ranges.
