Bevel Gear Pinion Hardware 2M Spur Gear 28T To 43T 20mm High Torque Hardened Steel Transmission Gear

2M Spur Gear Pinion 28-43 Teeth, 20mm Thick, 45# Steel
✔️ 2M spur gear, 28-43 teeth, 20 mm thick, HF quenched steel

This spur gear is a high-strength, high-torque transmission component used in mechanical drive systems. It’s commonly found in gearboxes, power transmission assemblies, robotics, milling machines, and CNC equipment. It features 28-43 teeth, 20 mm thickness, and 45# steel with high-frequency quenching to harden the teeth for wear resistance. Note: the internal holes are processing holes and must be reworked by the user for proper bore dimensions.

✅ Model: 2M spur gear, 28-43 teeth, 20 mm thick
✅ Material: 45# steel for durability
✅ Pitch: 6.28 mm tooth pitch for accurate meshing
✅ Heat treatment: High-frequency quenching for wear resistance
✅ Finish: Smooth surface, easy to clean and maintain
✅ Bore caution: internal holes are processing holes and require rework

💡 What is a spur gear used for in mechanical drive systems?
Spur gears are used to transfer rotation and torque between parallel shafts with simple, reliable engagement.
- Handy for driving mechanisms in machines like CNCs, gearmotors, and robotics
- They provide straightforward spacing and predictable backlash
- Material choices like 45# steel and heat treatment boost life
- Proper bore finishing and alignment are essential for good mesh
