|Publication Date:||20 March 2015|
|ICS Code (Rolling bearings):||21.100.20|
This Standard specifics the radial internal clearance for the following types of rolling bearings (hereafter referred to as "bearings').
- Deeproove ball bearings (except those for insert bearings)
- Double-row self-aligning ball bearings
- Cylindrical roller bearings
- Machined ring needle roller bearings
- lbroidal roller bearings (r.hotnixAnnts.a.r.u
- Double-row self aligning roller bearings
The radial internal clearance values specified in this Standard shall apply to five types of bearings with cylindrical bore (except the toroidal roller bearings) shown above and three types of bearings with tapered bore (double-row self-aligning ball bearings. cylindrical roller bearings and double-row self-aligning roller bearings).
