Please see page 31 for more details.③ The backlash values shown in the table are the theoretical values for the backlash in the normal direction for a pair of identical gears in mesh.④ Products marked with “**” have a small amount of material between the corner of the keyway and the tooth root. This mode of failure must be considered when selecting these gears.
