Key benefits Provides a bevel gear pair for 90degree power transmission in compact drive systems. Includes two gears in one package: Beval Gear 1.2M20T and Beval Gear 1.2M30T, offering flexible pairing options. Made from 45# steel for strength and machinability in typical gear applications. A costeffective solution for projects that require bevel gears. Specifications and contents Material: 45# steel Surface condition: the surface may show rust on some hardened gears Package includes: 1 piece Beval Gear 1.2M20T and 1 piece Beval Gear 1.2M30T Note: inner diameter bore and mounting method need to be processed by the user to fit their application Important usage notes Inner bore size and fixing method are not provided and require customer machining to fit your shaft and housing. These gears are for users who will machine the bore and implement their own mounting solution. Use scenarios DIY robotics: use the Beval Gear pair to assemble a 90degree drive stage in a small robot where you machine the bore to fit the motor shaft and the joint housing. Hobby CNC or automation projects: pair the 1.2M20T and 1.2M30T gears in a custom bevel gear train, machining bore and mounting to suit your frame and bearings. Lightweight transmission systems: implement in compact gear trains where of bore and fixation method is required to meet specific mounting tolerances.
