KSSAG2.5-30 is a metric spur gear with module 2.5, 30 teeth, and an H7 bore for J Series mounting. Made from S45C steel, it features induction-hardened teeth at 50-60HRC and a black oxide coating excluding the tooth surface. Pitch diameter is 75 mm, outside diameter 80 mm, face width 20 mm. Allowable bending strength torque is 78.7 N·m, surface durability torque is 8.03 kgf·m. Backlash ranges from 0.10 to 0.20 mm, and weight is 0.81 kg. It meets JIS grade N7 per JIS B1702-1:1998. Secondary operations are prohibited on teeth. Bore tolerance degrades after hardening. Requires keyway for shaft mounting and parallel shaft alignment to prevent uneven wear.
