Abstract

The invention relates to the field of bearings, and discloses a linear bearing applicable to a square tube. The linear bearing comprises a bearing outer sleeve, a first retainer and a plurality of first rolling bodies; the first retainer is provided with a plurality of spaced circulating roller paths; the first rolling bodies are connected in the circulating roller paths in a rolling manner; the first retainer comprises a first frame body and a second frame body arranged outside the first frame body in a sleeving manner; each circulating roller path comprises a first roller path body arrangedon the first frame body and a second roller path body arranged on the second frame body, a square sliding hole used for sleeving the square tube is formed in the first frame body in the axis direction, the first roller path body communicates with the sliding hole of the first frame body to form a first crack groove, the second roller path body communicates with the outer side of the second frame body to form a second crack groove, the first crack groove and the second crack groove are formed in the axis direction of the bearing outer sleeve, the widths of the first crack groove and the secondcrack groove are smaller than the diameter of each first rolling body, the first rolling body in the first crack groove abuts against the square tube, and the first rolling body in the second crack groove abuts against the inner wall of the bearing outer sleeve.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a linear bearing applicable to square tubes. Background technique [0002] Linear bearings are important accessories in the mechanical field. Currently, linear bearings on the market include bearing housings, cages inside the bearing housings, and rolling elements inside the cages. The cages on the market are all ring-shaped and used to wear cylindrical As for the guide rail, there is currently no linear bearing designed to pass through square tubes on the market. Square tubes are also widely used in different fields. The linear bearings with ring cages currently on the market cannot be applied to square tubes. Contents of the invention [0003] The present invention provides a linear bearing applicable to square tubes, aiming at the disadvantage that ordinary linear bearings on the market cannot be applied to square tubes. [0004] In order to solve the above-mentioned technical probl...
