Miter Transmission Miniature Bevel Gearbox — 1pcs Compact, rightangle 1:1 bevel gearbox designed to convert rotary motion 90 degrees with a 4 mm shaft interface. Ideal for tight mechanical assemblies where space and alignment require a dependable miniature rightangle drive. Key benefits Converts rotary motion by 90 degrees with a true 1:1 ratio, preserving input speed and direction for compact drive layouts. Miniature, spacesaving design simplifies packaging in small devices and hobby projects. Direct compatibility with 4 mm shafts reduces the need for adapters and makes integration fast and reliable. Singlepiece supply (1pcs) for quick replacement or integration into prototypes and small assemblies. Key attributes Functionality: Miter (bevel) transmission for rightangle power transfer; commutator/pinion mechanical gear arrangement for meshed bevel operation. Ratio: 1:1 (equal input and output rotational speed). Orientation: 90 degrees rightangle converter. Shaft size: 4 mm shaft interface on the driven/input/output as specified. Quantity: 1pcs included. Size class: Miniature — intended for compact mechanical systems and small gear trains. Compatibility: Designed to work with shafts and couplings sized to 4 mm; fits applications requiring a miter/bevel 1:1 gearbox. Typical applications Small robotics and automation: routing motor output to perpendicular joints or actuator shafts in compact robots and articulated mechanisms. Hobby models and RC: steering linkages, drive transfers, and layout where a compact 90° gearbox is required. Precision instruments and DIY gear trains: small assemblies, prototypes, and mechanisms where a reliable 1:1 rightangle transfer is needed. Installation and use notes Designed for direct coupling to 4 mm shafts; verify shaft fit and alignment before final assembly. Intended for miniature, low to moderateload applications typical of hobby, prototype, and instrument use. Refer to the seller listing or technical documentation for material and load specifications. Inspect gear meshing and secure mounting to ensure smooth operation and long service life. Included 1pc miniature miter/bevel gearbox, 90° converter, 1:1 ratio, 4 mm shaft.
