Specifications

What Are SK25 Linear Shaft Supports Used For?

SK-series shaft supports are the industry-standard solution for clamping and supporting smooth rods in linear motion systems. The SK25 variant fits 25mm rods perfectly, making it the go-to choice for medium-to-large 3D printers, CNC plasma tables, and automated gantry systems. By securing both ends (and midpoints) of a shaft, these supports eliminate sag, flex, and misalignment — the main enemies of print quality and cutting accuracy.

Compatible With

• 25mm smooth rods & linear shafts
• RepRap, CoreXY, and other open-frame 3D printer builds
• CNC router and laser engraver frames
• Linear actuator and conveyor systems
• DIY automation & robotics projects

Frequently Asked Questions

Q: What shaft diameter does the SK25 linear shaft support fit?

A: The SK25 is specifically designed for 25mm diameter smooth linear rods and shafts. It provides a secure, stable clamp around the shaft without restricting axial motion of the carriage or bearing block running along it.

Q: How many pieces are included in this listing?

A: This listing includes 2 pieces of the SK25 shaft support, which is typically enough to support both ends of a single linear shaft in most 3D printer and CNC setups.

Q: Are these SK25 supports compatible with standard 3D printer frames?

A: Yes. The SK25 linear shaft support is a universal, industry-standard design with standard bolt hole patterns that fit most open-frame 3D printers, CNC routers, and DIY linear motion builds that use 25mm smooth rods.

Q: What material are these shaft supports made from?

A: Kande Bearings SK25 supports are constructed from rigid metal alloy, providing the structural strength needed to hold 25mm shafts firmly in place under continuous motion and mechanical load, ensuring long-term dimensional stability.
