Linear Motion Guideways
Heavy-load linear rails and block assemblies designed for smooth, accurate, and rigid motion on CNC machinery.
LM guideways are precision rail-and-block systems that guide a CNC machine's axis movement with minimal friction and near-zero backlash, ensuring positioning accuracy during high-speed multi-axis motion.
- Recirculating Bearings: Internal steel balls continuously circulate within the block for ultra-low friction travel.
- High Rigidity: Four-row circular arc contact design allows the guides to absorb loads from all directions.
- Dust Sealing: Integrated end seals and bottom seals prevent wood dust and chips from ruining the bearings.
Why Choose TriQuench LM Guideways?

Self-Aligning
Absorbs installation errors due to surface inaccuracies, ensuring smooth travel.
Dust Protection
Integrated end seals prevent wood dust and metal chips from entering the bearing block.
Frequently Asked Questions
What are LM guideways used for in a CNC machine?
LM (Linear Motion) guideways guide the X, Y, and Z axes of a CNC machine, allowing the heavy gantry and spindle to slide smoothly and accurately with minimal friction.
What is the difference between HGH and HGW blocks?
HGH refers to square blocks which are compact and bolted from the top, while HGW refers to flanged blocks which provide a wider mounting surface and can be bolted from the top or bottom.
How often should I lubricate linear rails?
In a standard CNC router environment, LM blocks should be greased every 100km of travel or roughly every 1-2 months, depending on dust exposure and usage hours.
