Your existing gear it replaces should be 80 also but does not have to be. Commonly used to transpose the feed rates on metal lathes to allow cutting of metric sized threads.
While not perfect this IS the most accurate combination, besides the factory stock 127/100 tooth gear. This 80/63 gear ratio is 1/1.27. The resultant error is 0.0025 per foot of threading! Powdered Metal Bronze (SAE 841) oil impregnated bushing.
There IS also an oil hole if you desire to oil directly. (Makes me feel better ;>). 0.450 this provides enough offset to clear each other an retain FULL 0.375 engagement. 0.625 (retain use of any existing bushings). 3d printed plastic high resolution gears.
Gear Width: 0.375 Bore Diameter. 0.5625 9/16 with 1/8 key way. You can replace your current 80T gear with this Transposing gear with NO CHANGES. You will be pleased with the reduction in gear noise.Run it all the time if you wish! I have run these gears against STEEL gears and other PLASTIC gears for MANY hours of use. I have accidentally had SWARF sucked into the plastic gears.
Had to dig it out! I HAVE EPERIENCED NO MEASURABLE WEAR AND NO FAILURE TO DATE! These gears seem to be REALLY TOUGH! I have been very impressed and think you will be to!
Fit and usage is the BUYERS RESPONSIBILITY! I have not tested EVERY listed gear. In the chart to verify results of thread pitch cut.
