The 24 mm internal retaining ring beside the 22 mm and the 25 mm

The 24 mm is number 16, counting from the smallest, of the 17 DIN 472 internal retaining rings published here, from 8 mm to 25 mm.

• Ring thickness (s): 1.2 mm on the 24 mm internal retaining ring, against 1 mm on the 22 mm and 1.2 mm on the 25 mm.
• Ring thickness, limits (s_lim): 1.14 to 1.2 mm on the 24 mm internal retaining ring, against 0.94 to 1 mm on the 22 mm and 1.14 to 1.2 mm on the 25 mm.
• Free diameter (d3): 25.9 mm on the 24 mm internal retaining ring, against 23.5 mm on the 22 mm and 26.9 mm on the 25 mm.
• Free diameter, limits (d3_lim): 25.69 to 26.32 mm on the 24 mm internal retaining ring, against 23.37 to 23.92 mm on the 22 mm and 26.69 to 27.32 mm on the 25 mm.
• Lug height (a): up to 4.4 mm on the 24 mm internal retaining ring, against up to 4.2 mm on the 22 mm and up to 4.5 mm on the 25 mm.
• Radial width (b): 2.6 mm (reference) on the 24 mm internal retaining ring, against 2.5 mm (reference) on the 22 mm and 2.7 mm (reference) on the 25 mm.
• Plier hole diameter (d5): at least 2 mm on the 24 mm internal retaining ring, the same on the 22 mm and the 25 mm.
• Groove diameter (d2): 25.2 mm on the 24 mm internal retaining ring, against 23 mm on the 22 mm and 26.2 mm on the 25 mm.
