HIWIN linear bearing is the most linear rail carriage which is used on all cnc wood router machines, includes wood router basic machine, auto tool changing cnc router, multi spindle cnc router, nesting cnc router and cnc foam milling machine. Besides HIWIN, PMI and CSK are another two popular brands also. HIWIN, PMI and CSK all is from Taiwan.

Linear Carriage Type:
There are two types of blocks: flange and square. The flange type block is better for heavy moment load application than square type because of the lower assembly height and wider mounting surface. That’s why flange type linear bearing is usually used on Y-axis of multi-spindle cnc router machines like 8 spindles and 12 spindles cnc router.

Advantage and Features of Linear Guide
1) High positional accuracy, high repeatability, high motion accuracy
2) High speed motion is possible with a low driving force
3) Easy installation
4) Easy lubrication
5) High rigidity with four-way load design
6) Interchangeability- Linear guideways can be easily replaced should any damage occur.

HIWIN Block
The series HG is the correct one suitable for cnc wood router machines. HG means heavy load ball type.
Features of HG series
1) Self-aligning capacity
2) By design, the circle-arc groove has contact points at 45 degrees. HG series can absorb most installation errors due to surface irregularities and provide smooth linear motion through the elastic deformation of rolling elements and the shift of contact points. Self-aligning capability, high accuracy and smooth operation can be obtained with an easy installation.
3) Interchangeability
4) High rigidity in all four directions
