Anchor KeyThis anchor key retains a gear, pulley, or hub on a shaft against rotation, seating into matching keyways in both the shaft and the mating component. Service techs replace keys during overhauls when shear damage or wear prevents reliable joint retention. A failed key causes the hub to slip on the shaft and damages both surfaces, leading to expensive secondary repair. Sold as an aftermarket replacement, contact us to verify key length, cross-section, and material grade before ordering, since visually similar keys vary in actual dimensions, and substituting between sizes leaves a slack joint that fails under operating torque or fails to fit the keyway entirely.Aftermarket replacement part, cross-references original part number AC04010-00516.Need help confirming fit?
