| Note 1: The minimum size in the table means that the sleeve raw material adopts the mechanical properties index of No. 45 steel in GB/T699 (the measured yield strength and ultimate strength should not be less than 355Mpa and 600Mpa respectively), and the sleeve manufacturer has a good quality control level. The minimum size that can be selected. Note 2: For the sleeve without cutting the outer surface, when the outer diameter of the sleeve is less than or equal to 50mm, the increase should not be less than 0.4mm on the basis of the minimum outer diameter listed in the table; when the outer diameter of the sleeve is greater than 50mm , should be added to the minimum outer diameter size listed in the table should not be less than 0.8mm. Note 3: The minimum size of the measured sleeve shall be measured in at least two directions, and the smallest value shall be used for judgment. | |||||||||||||||
