This kit allows you to swap the stock Ratrig chinese Z0 X rail with a Hiwin Z1 preloaded rail for an standard CoreXY, Hybrid or IDEX VCore 4

Context:

Linear guide preload eliminates the clearance between the carriage and the rail Manufacturers achieve this by using specific sized ball bearings.

By eliminating the clearance, it increases rigidity and reduces deflection when external loads are applied. In a 3D printer, rails preload is a key factor to increase precision and improve the input shaper specs since no preload are cheaper, but get some play, more sensible to vibration across our high accelearions values..

The ball bearings used to achieve preload are slightly larger than the distance between the raceways of the linear guide and the rail. Common preload amounts are between 2 and 8 percent.

Most commonly used rail are Z0 (No specific preload)

Choosing the right pack:
