- 12x18x6mm Aluminium Spacers are precision-engineered components designed to the same DIN988 standard dimensions as our precision shims. Perfect for use in aluminium extrusion systems, these spacers provide reliable separation and support for mounting stepper motors, spacing pulleys, wheels, and other components. Made from lightweight, corrosion-resistant aluminium, they ensure optimal stability and accurate alignment in custom assemblies. Key Features High-Quality Material: High-quality aluminium construction ensures a balance of strength and low weight. Precision Dimensions: Consistent ID and OD based on DIN988 standards for reliable compatibility and fit. Versatile Sizes: Available in a wide range of sizes and lengths to suit various applications and requirements. Versatile Application: Ideal for mounting motors, spacing wheels, spacing pulleys, or other components in aluminium extrusion assemblies. Application Aluminium Spacers are specifically designed for use in custom assemblies built with aluminium extrusions. They are commonly used to stand off components like stepper motors, space out wheels and pulleys, or provide precise separation in mechanical and structural systems. Their lightweight design makes them particularly suitable for applications where maintaining minimal weight is essential without sacrificing strength. Perfect for engineers, fabricators, and hobbyists, these spacers ensure optimal alignment and spacing in aluminium extrusion projects.
