Bondtech drive gear kit in hardened and surface protected steel. Precision cnc-machined. Super sharp teeths for maximum grip on the filament. The perfect choice for a high-performance feeding system. Extremely high wear resistance for use with abrasive filaments. These drivegear kits come as a set consisting of a primary drive gear, a secondary drive gear, bearings and a shaft. Gear set for filament size 1.75 mm, primary gear with inner diameter 5 mm, secondary gear with two needle bearings, M3x2 setscrew and one 3x20 mm shaft. Gear set for filament size 1.75 mm, primary gear with inner diameter 8 mm, secondary gear with integrated needle bearings, M4x3 setscrew and one 4x22 mm shaft. Gear set for filament size 2.85 – 3.0 mm, primary gear with inner diameter 8 mm, secondary gear with integrated needle bearings, M4x3 setscrew and one 4x22 mm shaft. A Lithium based grease is recommended to use on the gear section and inside the needle bearings for low friction and to avoid wear. A small dab of grease is enough.
