1.2.5 Block types
嗨provides square and flange blocks for its linear guideways. Given their low
height and larger mounting surface, flange blocks are better suited to large loads.

1.2.6 Preload
1.2.6.1 Definition
每种铁路类型都可以预加载。超大球用于此目的。通常是
linear guideway has negative clearance between track and balls to increase rigidity and
precision. The curve shows that the rigidity doubles at higher preload. For rails below
the nominal size of 20, a preload of no more than ZA is recommended to avoid the life-
