The 14 mm external retaining ring beside the 13 mm and the 15 mm

The 14 mm is number 12, counting from the smallest, of the 18 DIN 471 external retaining rings published here, from 3 mm to 20 mm.

• Ring thickness (s): 1 mm on the 14 mm external retaining ring, the same on the 13 mm and the 15 mm.
• Ring thickness, limits (s_lim): 0.94 to 1 mm on the 14 mm external retaining ring, the same on the 13 mm and the 15 mm.
• Free diameter (d3): 12.9 mm on the 14 mm external retaining ring, against 11.9 mm on the 13 mm and 13.8 mm on the 15 mm.
• Free diameter, limits (d3_lim): 12.54 to 13 mm on the 14 mm external retaining ring, against 11.54 to 12 mm on the 13 mm and 13.44 to 13.9 mm on the 15 mm.
• Lug height (a): up to 3.5 mm on the 14 mm external retaining ring, against up to 3.4 mm on the 13 mm and up to 3.6 mm on the 15 mm.
• Radial width (b): 2.1 mm (reference) on the 14 mm external retaining ring, against 2 mm (reference) on the 13 mm and 2.2 mm (reference) on the 15 mm.
• Plier hole diameter (d5): at least 1.7 mm on the 14 mm external retaining ring, the same on the 13 mm and the 15 mm.
• Groove diameter (d2): 13.4 mm on the 14 mm external retaining ring, against 12.4 mm on the 13 mm and 14.3 mm on the 15 mm.
