Out diameter: 12 mm Length: 18 mm Bore: 2 mm, 3 mm, 4 mm, 5 mm, 6 mm Zero backlash: The monolithic design provides zero backlash and precise alignment via elastic deformation. This is critical for precision applications such as robotics and CNC machining Key benefits Improves precision: Monolithic onepiece construction eliminates backlash, delivering repeatable positioning and better control in moving assemblies. Flexible bore options: Compatible with common shaft sizes using bore options of 2, 3, 4, 5, or 6 mm. Robust and simple: Onepiece design minimizes assembly complexity and potential loosening over time, supporting reliable performance in demanding environments. Specifications at a glance Out diameter: 12 mm Length: 18 mm Bore variants: 2 mm, 3 mm, 4 mm, 5 mm, 6 mm Backlash performance: Zero backlash with precise alignment achieved through elastic deformation Recommended use scenarios Robotics: Mounts and joints requiring precise alignment and zeroplay to maintain predictable motion and accuracy. CNC machining: Tooling mounts or spindlerelated fixtures where accurate shaft alignment is essential for repeatable results. Precision automation and measurement equipment: Fixtures and assemblies that demand tight shaft alignment and minimal positional error.
