This insert absorbs vibration, reduces shock transmission, and compensates for minor angular, parallel, and axial shaft misalignment — advantages that rigid couplings cannot offer. This makes the Kande XL3 ideal for precision CNC and motion control applications.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this coupling suitable for both stepper motors and servo motors?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The clamp-type design and flexible jaw structure make the D64L90 suitable for connecting stepper motors, servo motors, and ballscrew\/leadscrew assemblies in CNC machines and industrial automation systems, provided the shaft diameters match one of the available bore sizes.\u003c\/p\u003e\n\u003ch4\u003eQ: How does the clamp-type design work?\u003c\/h4\u003e\n\u003cp\u003eA: The clamp-type hubs feature a slit and tightening screw that securely clamps around the shaft, eliminating slippage and minimizing backlash. This provides a more reliable and precise connection compared to traditional set-screw designs, especially under variable or reversing loads common in CNC applications.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
