Irregularly shaped guide rail double row ball roller assembly

Abstract

This utility model discloses a double-row ball bearing roller assembly for irregularly shaped guide rails, including a roller shaft and rollers. The rollers are fitted outside the roller shaft and can reciprocate along the axial direction of the roller shaft. The rollers and the roller shaft together form a receiving space, and a retainer is installed in the receiving space. Multiple ball bearings are spaced apart on the retainer. The inner end face of the rollers and the outer end face of the roller shaft are respectively recessed to form inner deep grooves and outer deep grooves for partially accommodating the multiple ball bearings. The technical solution proposed by this utility model can inherit the original roller assembly fixing method and structure after introducing a bearing structure. While meeting assembly compatibility, it can also significantly reduce the friction with the guide rail, making pushing and pulling smoother and more seamless, thereby meeting the user's growing experience needs.
