SGR15N 38mm Dual-Axis Linear Guide Rail & Block Set for CNC

SGR15N Blackened Dual-Axis Linear Guide Rail & Slide Block Set – 38mm

Upgrade your CNC router, woodworking machine, or precision linear motion system with the SGR15N Blackened Dual-Axis Linear Guide Set. Each set includes 1× SGR15N roller guide rail and 1× SGB15N slide block, delivering smooth, accurate, and reliable linear motion for demanding workshop and industrial applications.

Why Choose the Blackened SGR15N Over Standard White Rails?

The black oxidation treatment applied to this guide rail offers significant advantages over standard white SGR guide rails:

• Superior corrosion resistance – the black oxide coating provides an added layer of protection against moisture and wear
• Higher-quality bearings – smoother rolling action and extended service life
• Enhanced durability – better suited for heavy-duty, continuous-use environments

Frequently Asked Questions

Q: What does the SGR15N linear guide set include?

A: Each SGR15N set includes one SGR15N dual-axis linear guide rail (38mm width) and one SGB15N roller slide block. The blackened finish provides improved corrosion resistance and bearing quality compared to standard white guide rails.

Q: Can the rail length be customized for my CNC machine?

A: Yes! The SGR15N guide rail length is fully customizable. Simply contact us with your required dimensions before placing your order, and we will accommodate your specific project needs.

Q: What is the difference between the SGB15N-3UU and SGB15N-4UU locking blocks?

A: Both the SGB15N-3UU and SGB15N-4UU are locking-style slide blocks that can be locked securely in position using a standard L-wrench. They are compatible with the SGR15N guide rail and differ mainly in the number of roller bearing rows, affecting load capacity and rigidity.

Q: Is this linear guide suitable for woodworking CNC routers?

A: Absolutely. The SGR15N dual-axis linear guide is widely used in CNC woodworking machines, milling setups, laser engravers, and other precision motion systems requiring smooth, stable, and accurate linear travel.
