National test area The center shaft test of the three-card center shaft is the production of the wheel shaft. The special wheel diameter can be moved. The pipe can be used for the whole level: there are relatively safe parts that meet the requirements of the movement, the movement should be flexible, and the pipe should be able to meet the requirements of the GB. When the pipe end line is to be drawn, the control of the pipe should not be too large. The filter value of Table 5: 5
