Clearance of Linear Bearings

The inner and outer diameters of the linear bearing adjustment type and open type bearing of the linear bearing are measured before the cut, and there will be some elastic deformation after the cut, and the matching clearance should be measured in the bearing seat (similar to the steel retainer bearing and KH bearing ). The adjustment direction of the bearing seat with adjustable clearance should be perpendicular to the direction of the bearing cut to ensure uniform clearance. The structural characteristics of the linear bearing cannot be rotated, and good guidance is required, so the linear bearing is generally two shafts + four sets Bearings or two shafts + two sets of elongated bearings are used as a combination. The installation of the two shafts should be straight. After the entire combination is assembled, the transmission mechanism must be flexible and unobstructed by hand pushing and pulling, and the transmission power must be sufficient to overcome the bearing friction. Resistance, linear bearing friction resistance is approximately one thousandth of the working load
