SGR15 Linear Guide Rail & SGB15 Roller Slide Block Set – 46mm

SGR15 Dual-Axis Linear Guide Rail & SGB15 Roller Slide Block Set

Precision-engineered for smooth, stable linear motion, this SGR15 46mm built-in dual-axis roller linear guide set delivers consistent, low-friction performance for CNC machines, 3D printers, automation systems, and industrial equipment. Each set includes one SGR15 linear guide rail and one SGB15UU roller slide block, ready to install for immediate use.

Product Highlights

• Dual-Axis Design: Built-in dual-axis roller structure provides superior rigidity and smooth travel along the entire guide length.
• 46mm Guide Width: Model SGR15 offers a robust 46mm profile suited for medium-to-heavy load applications.
• Multiple Length Options: Available in 300mm, 400mm, 500mm, 600mm, 700mm, and 800mm — custom lengths also available on request.
• Lockable Slider Options: SGB15-3UU LOCKING and SGB15-4UU LOCKING variants can be firmly secured using an L-wrench for applications requiring a fixed position.
• Set Includes: 1 × SGR15 linear guide rail + 1 × SGB15UU roller slide block per set. (If ordering a single SGB15-3UU block, only the block is included.)
• Precision Roller Construction: Hardened steel rollers ensure accurate, repeatable positioning with minimal play.
• Broad Compatibility: Compatible with CNC routers, laser cutters, linear actuators, automated assembly systems, and DIY motion platforms.

Frequently Asked Questions

Q: What is included in one set of the SGR15 linear guide?

A: Each set contains one SGR15 linear guide rail and one SGB15UU roller slide block. If you order a single SGB15-3UU block separately, only the block will be included — not the rail.

Q: Can the SGR15 guide rail be cut to a custom length?

A: Yes. In addition to the standard lengths of 300mm, 400mm, 500mm, 600mm, 700mm, and 800mm, custom lengths are available. Please contact us with your specific requirements before placing your order.

Q: What is the locking feature on the SGB15-3UU and SGB15-4UU LOCKING blocks?

A: The SGB15-3UU LOCKING and SGB15-4UU LOCKING slider variants feature a built-in locking mechanism that can be engaged using a standard L-wrench (hex key). This allows the slider to be fixed firmly in position on the guide rail — ideal for applications where controlled, stationary clamping is required.

Q: What types of machines or projects is the SGR15 roller linear guide suitable for?

A: The SGR15 dual-axis roller linear guide is well-suited for CNC routers, 3D printers, laser cutting machines, linear actuators, robotic arms, automated assembly lines, and DIY precision motion platforms. Its 46mm profile and roller design make it ideal for medium-to-heavy duty linear motion needs.
