8mm Linear Motion Rail Kit 39.37 Inch 1000mm With 2 Shaft Rods 4 SCS8UU Bearings And 4 SK8 Aluminum Rail Supports For 3D Printer DIY And CNC Projects Pro Grade Setup

8mm Linear Rail Kit with 2x1000mm Rails and Bearings
✔️ 2x 1000mm rails, 4 SCS8UU blocks, 4 SK8 supports and mounts

Designed as a pro-grade linear motion kit for CNCs, 3D printers, and automation projects. It pairs chrome-plated rails with sturdy bearing blocks for smooth, precise travel and repeatable positioning across X, Y, and Z axes. The kit uses 8mm rails (1000mm long) with hardened steel bearings in aluminum housings for durability and resistance to wear, and it can be customized to different lengths and end-processing needs to fit your build.

✅ 2x 1000mm rail rods, 8mm diameter, chrome plated (1000mm / 39.37 in)
✅ 4 SCS8UU bearing blocks with aluminum housing, hardened steel inside (58-64 HRC)
✅ 4 SK8 fixed supports for stable mounting on frame
✅ Precision specs: straightness below 5 μm/100 mm, surface Ra 0.8
✅ Customizable lengths and end-processing options available for your setup
