Collar Double Split Key benefits Double split design enables easy adjustment and precise positioning of components on a shaft. strength and strong locking force provide longlasting durability in demanding applications. Reliable performance across automotive, robotics, and manufacturing environments. Size and compatibility Available in three inside diameters: 20 mm, 25 mm, and 30 mm. Outer diameter options: 40 mm, 45 mm, or 54 mm, with a uniform width of 15 mm. Designed to fit a range of equipment and machinery that require secure shaft mounting and adjustable positioning. Easy installation and removal Twopiece construction allows quick, hassle installation. Open the collar, place it around the shaft, then tighten the screws to secure it in place. Saves time and reduces maintenance effort during setup and adjustments. Function and performance Used as positioners, spacers, stops, and bearing surfaces. Securely holds gears, pulleys, sprockets, or other components onto shafts. Provides adjustability that supports smooth operation and reliable alignment in rotating assemblies. Practical applications (2–3 scenarios) Robotics: mounting servo motors and aligning gears for precise, repeatable motion. Automotive manufacturing: securing pulleys or sprockets on shafts during assembly and adjustment. Conveyors and general machinery: serving as stops, spacers, and bearing surfaces to maintain gear/pulley alignment and reduce play.
