Single-piece conical (bevel) gear — form 2.5, 30 teeth, 90° configuration, with multiple bore options and a 20 mm bore that includes a 6 mm keyway. Key benefits Right-angle power transmission: 90° geometry allows compact, efficient torque transfer between perpendicular shafts. Versatile fit: multiple bore sizes (15, 17, 18, 20, 22, 25, 28, 30, 32, 35 mm) let you match common shaft diameters without custom boring. Positive, reliable mounting: the 20 mm bore option includes a 6 mm keyway for secure torque transmission and repeatable alignment. Simplifies inventory and replacements: a single gear design with many bore options reduces the need to stock many different gears. Main specifications Type: conical (bevel) gear, single piece Form: 2.5 Teeth: 30 Angle: 90 degrees Bore options: 15 mm, 17 mm, 18 mm, 20 mm, 22 mm, 25 mm, 28 mm, 30 mm, 32 mm, 35 mm Keyway: 20 mm bore option includes a 6 mm keyway Function and compatibility Designed to mesh with mating bevel gears of compatible form (2.5) and tooth geometry for accurate engagement and steady operation. Use with shafts matching the listed bore diameters; the 20 mm bore with 6 mm keyway supports keyed shafts for positive torque transmission. Suitable for retrofits or OEM assemblies where a 90° gear interface and specified tooth form are required. Performance and installation notes Single-piece construction provides dimensional stability and straightforward installation. Ensure mating gear has compatible form and tooth profile for correct meshing and noise/minimized wear. For keyed installations, use the 20 mm bore with the 6 mm keyway; for other bores, secure the gear to the shaft using appropriate press fit, set screws, or shaft retention methods as required by your application. Typical applications Right-angle gearboxes and drive assemblies where a compact 90° change of direction is needed. Industrial machinery and conveyors for redirecting torque between perpendicular shafts. Agricultural equipment, small machine tools, or other mechanical systems requiring a reliable bevel gear with multiple bore options for different shaft sizes. Ordering and selection tips Confirm the mating gear’s form and tooth count to ensure compatibility with this 2.5 form, 30-tooth gear. Choose the bore size that matches your shaft; select the 20 mm bore with 6 mm keyway if a keyed connection is required. If heat treatment or specific material properties are required for your application, specify those requirements when ordering (material and treatments are not specified in this listing). This conical gear provides a practical, adaptable solution for right-angle drives, offering consistent geometry (2.5 form, 30 teeth) and multiple bore options including a keyed 20 mm bore for secure installations.
