Miter Transmission miniature bevel gearbox designed for compact rightangle power transfer. This singlepiece 1:1 right angle converter changes the direction of rotation by 90 degrees while keeping input and output speed equal, making it ideal for tight mechanical layouts and spacelimited assemblies. Key benefits Converts rotational motion 90 degrees without changing speed or gear ratio (1:1), solving routing and packaging problems in confined assemblies. Miniature size with 4 mm shaft interface accommodates small drives and driven components where larger gearboxes won't fit. Simple, mechanical bevel (miter) gear arrangement provides a straightforward, reliable solution for rightangle power transfer. Supplied as 1pcs unit for singleinstall applications or small projects. Key attributes Product: Miter Transmission miniature bevel gearbox Quantity: 1pcs Gear type: Miter / bevel gearbox (commutator pinion mechanical) Output angle: 90 degrees (rightangle gearbox) Gear ratio: 1:1 (equal input and output speed) Shaft diameter: 4 mm (both input and output shafts with 4MM shaft interface) Function: Rightangle converter for redirecting rotary motion Functionality and compatibility Transfers torque and rotation at a right angle while maintaining the same rotational speed (1:1). The 4 mm shaft interface is compatible with shafts, couplings, and components designed for a 4 mm diameter connection. Compact miter design fits into constrained spaces where a straight coupling is impractical. Use with motors, small actuators, or mechanical linkages that accept a 4 mm shaft. Typical applications Small robots and hobbyist projects: change motor rotation direction to fit drive trains into compact chassis. Model machinery and scale mechanisms: implement rightangle drives in models, turntables, or steering linkages. Instrumentation and automation: route motion within enclosures or assemblies where space and alignment call for a 90degree gearbox. Installation notes Intended for mechanical assemblies that accept a 4 mm shaft. Ensure proper alignment and secure fastening of the shaft to the pinion or coupling before operation. Singlepiece supply (1pcs) is suitable for prototypes, repairs, or small production runs. This miniature miter transmission provides a compact, simple solution for reliable 90degree power transfer with a 1:1 ratio and 4 mm shaft interface.
