Features of Linear Guideways
Extremely Low friction.
Capacity of zero clearance motion, raising rigidity of the mechanical system.

Using double guides assembly, error homogenization effect can be attained, processing accuracy requirements can be lowered and cost of manufacture can be saved.
Suitable ratio of radius groove of raceway sectional plane assured that contact force turns small and carrying capacity and rigidity could be also raised greatly. Value of rolling friction is less than that of double-arc raceway.

Surface hardness processing makes guide good-adjustable, while the core part keeps good mechanical characters.
Designing process and manufacturing of mechanical structure is simplified
