Double Split Shaft Collar Bore 8mm OD 25mm Thickness 8mm 6061 Aluminum Alloy Anodized Surface H7 Bore Tolerance Locking Collar for CNC Machinery

This double split shaft collar is made from 6061 aluminum alloy and features an anodized surface for enhanced wear and corrosion resistance. Designed with two clamping splits, it provides stronger holding force and more uniform pressure distribution than single split collars, while preventing shaft surface damage. The precision H7 tolerance bore ensures accurate shaft alignment, reducing vibration and maintaining concentricity in linear and rotary motion. Its split construction allows for easy installation and adjustment without disassembling other components on the shaft. This versatile collar is ideal for use as a stop collar, spacer, or positioning ring in CNC machinery, automation systems, and precision mechanical assemblies. Combining lightweight strength with reliable performance, it is a practical solution for engineers and technicians in demanding applications.
