2. The diameter of the inner (outer) cylinder of a row of balls in the inner (outer) diameter bearing of the ball set.
3. The diameter of the inner (outer) cylinder of a row of rollers in the inner (outer) diameter radial contact roller bearing of the roller set.
4. The gap between the two theoretical end faces of the bearing nominal width ferrule (the opposite side of the washer) is used to limit the width of the radial bearing (thrust bearing height).
5. The bearing practice width is the spacing between the axial line of the radial bearing and the intersection of the two tangential planes of the ferrule practice end face that limits the bearing width. The inner ring end face and the outer ring end face limit the bearing width.
6. Bearing practice width error bearing difference between practice width and nominal width.
7. Radial runout of assembled bearing inner ring when the inner K ia different angular orientation; outer and inner hole radially between the maximum and minimum of the difference between a fixed point relative to the outer spacing of the dots in the angular orientation or at their. The rolling body near the two ends should be in contact with the inner surface of the inner or outer ring raceway or the inner ring reverse rib (tapered roller bearing), that is, the bearing parts are in a normal relative orientation.
8. Radial runout of assembled bearing outer ring when the outer ring K ea different angular orientation; between the maximum and minimum outer diameter of the radially outer and the inner ring relative to a fixed angular orientation difference interval above or adjacent to the point. The roll body at both ends shall be in the inner and outer ring raceway or the inner ring reverse rib (tapered roller bearing). The inner surface touch is the normal relative orientation of the bearing parts.
9. The inner ring end of the complete bearing faces the raceway of the raceway. The inner ring of the S ia is in a different angular orientation; the radial spacing from the inner core axis is equal to the half of the inner ring raceway touch diameter; the inner ring reference end face is opposite to the inner ring The difference between the maximum and minimum axial spacing between the fixed points of the outer ring. The inner and outer raceways should be touched by all the rolling bodies.
10. Sets of roller bearing outer end face of the outer ring channel S ea beating at a different angular orientation; radially away from the axis line spacing is equal to the outer ring raceway diameter at half the touch; the outer end face relative to the reference The difference between the maximum and minimum axial spacing between the inner ring and the fixed point. The inner and outer raceways should be in contact with all the rolling elements.
11. The end face bounces the inner hole S d at a radial distance from the inner ring axis line equal to half of its track touch diameter; the maximum and minimum axial direction between the plane perpendicular to the ferrule axis line and the ferrule reference end face The difference between the intervals.
