ADR bearing designation: A412R
This designation is only defining the size and shape of the ball bearing. Materials and performances have to be detailed during study and quotation.
Bearing Dimension
Dimensions values
* For Protected bearing (ZZ; FF; -2RS), Width B and Flange width C1 can be larger depending of the size of bearing, please contact us
Basic Load Rating of Bearing
To improve Capacity and Life time:
Basic load rating of bearing
For Bearing Protected with shields or seals:
Tolerance, internal clearance and calibration
Tolerance class selected usually
Class “T4” for Rigid ball bearing
Class “TA4” for Thin Section ball bearing
For others tolerances:
Assembling configuration
ADR proposes different bearings pair configuration in standard, for example:
- DO for Duplex ball bearings in Back-to-Back configuration
- DX for Duplex ball bearings in Face-to-Face configuration
To define assembling configuration and preload value:
Speed limit
Mean mass
