  • Diametral pitch of 12 for applications requiring a balance between transferring torque and controlling changes in speed and direction of rotation with precision

Received a TS1224 with a sticker labeled TS1221 stuck on the packaging. The gear is stamped TS1224 and has 24 teeth, so definitely the wrong part. Also had both keyway and set screw, which aren't included by default on the stock TS1221 or TS1224.

I was looking for an exact match requirement for a piece of industrial machinery. I couldn't believe there was one on Amazon. Received it, installed it and the equipment is working fine. Thanx, Amazon.
