The present invention relates to a roller type linear guideway which comprises
the rail, the slide block, the roller-model, the recirculating-model, and the ender
cap. The recirculating-model is make up of two half recirculating-models which
are assembled together at a specific angle, and each of the half recirculating-models
comprises two U-shaped recirculating piece which includes a return portion, a supporting
portion and a reflow portion, the recirculating paths of the roller-models intersect
to form a x-type turn. Therefore, there are no a lot of accessories, that can reduce
time of fabrication and can save the cost of manufacture.
