The Eccentric Spacers (5mm Bore, 10Hex, 8.5mm) are precision-machined components designed to provide adjustable spacing in V-slot linear rail systems, commonly used in CNC machines, 3D printers, and other motion control applications.

Key Features:

• Durable Construction – Made from high-quality metal for long-lasting performance.

• 5mm Bore Size – Ensures a perfect fit with standard 5mm bolts and hardware.

• 10mm Hex Shape – Allows for easy adjustment using a wrench to fine-tune wheel tension.

• 8.5mm Offset Height – Provides precise spacing control for optimal alignment.

• Versatile Application – Ideal for V-wheel motion systems in CNC routers, laser engravers, and 3D printers.

These eccentric spacers allow for adjustable wheel pressure against rails, ensuring smooth and accurate linear motion.
