177-313 27.5 *1 Actual diameter is marked in 10 µinch increments. (Dimension measuring position is the center of the height T.) *2 Cylindricity is defined as per JIS B 0621 Definitions and designations of geometrical deviations, Section 4.4 “Cylindricity.” Cylindricity is measured using three cross-sections between the top and bottom face of a ring, namely, close to the face near each side and the center. 0.00010 0.00012 5.3
