Claims15
An automatic-positioning linear guide, comprising:
- a stationary base, having pair of guiding rail sets provided at two lengthwise sides of a top surface thereof, wherein each of the guiding rail set has at least one guiding rail provided at one lengthwise lateral thereof and the guiding rail has a roller contacting portion jutting out the lateral of the guiding rail set;
- and
- a driven body, mounted on the stationary base, wherein at least one roller is provided at each of two sides of a bottom surface of the driven body and each said roller comprises two bearings and an axial shaft combining and fastening the two bearings to the driven body, in which two outer bushes of the two bearings jointly define an annular sliding groove at an exterior of the roller so as to receive the roller contacting portion of the guiding rail, whereby when the outer bushes of the bearings contact the roller contacting portion, an axis of the bearings deflects.
