The development of HIWIN QH type linear guideway is based on a four-row circular-arc contact,The HIWIN-QH series linear guide with synch motion technology offers smooth movement,superior lubrication,quieter operation and longer running life,there forethe HIWIN QH linear guide rail has industrial applicability.in he high tech industry where high speed,low noise,and reduced dust generation is required,the HIWIN-QH series is interchangeable with the HIWIN HG series.
The accuracyof QH series can be classified into normal(C),high percision (P),super precision(SP),ultra precision(UP),five lasses,please choose the class by referring the accuracy of applied equipmet
HIWIN QH Series is a preload can be applied to each guideway,oversized balls are used.Generally,a linear motion guide rail has a negative clearance between groove and balls in order to improve stiffness and maintain by the preload,the rigidity is doubled and the deflection is preload,the rigidty is doubled and the deflection is reduced by one half,the preload not larger than ZA would be recommernded for the model sze under QH20 to avoid an over preload affecting th liear guide rails life.
