Margin flange width flange width of the gap between the two ends. 10. Flange high flange height of the radial flange size. The flange is the height of the outer surface and the flange of radial distance between the surface. 11. Stopper ring groove diameter snap ring groove

diameter only moving part of the trough of the diameter cylindrical surface 12. stopper ring groove width snap ring groove width stopper ring groove at both ends of the axial distance. 13. Stopper ring groove depth snap ring groove depth only moving part of the cylindrical tank, cylindrical surface and surface between

The radial distance. 14. Aligning surface radius of aligning surface radius aligning seat, aligning Block, gaskets, aligning outer ring or aligning the seat of the spherical surface of the radius of curvature. 15. Aligning surface height centre sligning surface centre height thrust axis

By aligning the seat of the spherical shape of the curvature of the back of the Centre and the relative lap axis between the back of the axial distance. (D) of sub-components, parts and components the size of 1. Diameter ball diameter ball with the ball tangent to the surface of the two parallel distance between the plane. 2. Roller diameter roller China Bearing Review diameter

In roller axis perpendicular to the plane of the (radial plane), and roller tangent to the surface parallel to each other as the distance between the two tangent. Rated load calculation, the application of radial roller central plane. 3. Roller roller length include the length of roller end, the two radial

The distance between the plane. However, in the calculation of the rated load with the "roller length" is a roller self aligning ball bearing and Raceway in the shortest possible contact with the theoretical maximum length of exposure. 4. Ball Festival Circle Group diameter pitch diameter of ball set the ball bearings, a core component of the diameter of the circle. 5. Roller

The sub-group of circle diameter pitch diameter of roller set within a bearing roller in the middle of roller axis line running through the circle's diameter. 6. Balls group diameter (diameter) ball set bore diam deep groove ball bearings

But when the role of cathode polarization over a certain range, the precipitation will lead to a lot of hydrogen, so that coating has become porous and rough, loose, burned, or even powder form, instead of declining quality. Additive free fluoride content and boric acid content is too high or too low when the main concentration, the coating will have serious shortcomings. 4.2.7 the impact of temperature with increasing temperature, bath in the composition of the dissolution of the increase in the concentration of the desirable limit. DK which is conducive to the increase, thereby speed up the deposition rate. However, the temperature too high too quickly dissolved anode, anode slime increased so that the solution turbidity, coating nodulation. At the same time free fluoride boric acid, volatile organic stability agent to speed up, smell increasing deterioration of the environment. The temperature is too low free-boric acid precipitation, bath muddy, rough plating; Meanwhile DK or not to effect deposition slow, low production efficiency. 5 testing process used L9 (34) orthogonal test identified in the bath [Pb2 +], free [HBF4], free [H3BO3] DK and technical parameters of the best value. 5.1 anode composition test conditions: PbSn10; Temperature: 20 ~ 25 ℃; power: three-phase full-wave silicon rectifying; specimen geometry: 100 × 50 × 4; specimens lining (was plated base) the composition: CuPb22Sn2 ; Specimens lining the surface roughness: Ra0.4.
