Our component / drawing revision: [ ]
Assembly and mating interfaces: [ ]

Please review:
1. Controlled drawing and mating-hub sketch
2. Material grade and final condition
3. Bearing-seat and flat requirements
4. Sample quantity, production quantity and approval tests

Sample acceptance to agree:
1. Flat geometry: State depth, working length, end transition and any required angular orientation.
2. Journal relationship: Identify the bearing seats, datum features and geometric controls that affect rotation.
3. Axial position: Tie the locating shoulder to the mating hub and bearing stack.
4. Finished condition: State whether dimensions apply after treatment, grinding or coating.
