 Installed bearings are arranged in series, in addition to determine the inner and outer rings thickness measurement method or feel the law, also equipped to use a number only role of cylindrical spring bearing outer ring, in order to achieve the pre-load. The spring is calculated as follows: 
 Each spring force is 
 Where d - diameter of the spring wire (cm) 
 D - spring average diameter (cm) 
 R - spring allowable stress (40000-70000N / c ㎡) 
 n - the number of cylindrical spring 
 Diameter of spring wire 
 Spring pitch 
 Installation should be noted that several issues 
 must be equipped with the good inside and outside the spacer thickness, parallelism of the spacer surface of the two temple should not exceed 0. 002mm. 
 b The bearings must be matching. Each group of bearings outside diameter difference should be 0. 002-0. 003mm between the shell holes and 0. 004-0. 008mm, with the journal to keep 0. 0025-0. 005mm of gap. Using both thumbs in the actual installation, the bearing can just push with the best. 
 bearing hole and journal roundness, concentricity of the shell holes at both ends, and journal runout should not exceed 0. 003mm. 
 d in contact with the bearing ring face parts face paint inspection, the contact area of ??not less than 80%. 
 e. must be directed to install. About to all the highest point of the bearing inner ring radial runout at the journal runout lowest point, the highest point of the bearing outer ring radial runout is installed in the shell hole into a straight line.

 Installation should pay attention to 
 Installation does not allow drilling in the bearings, grooves, chamfers, endface. Easily lead to bearing ring deformation, affect the bearing accuracy and life, cutting out the metal easy access to the bearing surface, to accelerate the raceway and rolling element wear, the bearing resulting in premature failure. 
 (2) the installation does not allow hand hammer beat direct bearing rings. Installation of bearing the benchmark end celebration inward close to the shaft shoulder. Bearing reference face is to distinguish between the bearing face with or without typing, deep groove ball bearings, aligning ball bearings, cylindrical roller bearings, spherical roller bearings and needle roller bearings, a non-word face datum; angular contact ball bearings and tapered roller bearings and end with words as the datum. 
 Installation pressure should be added to the ferrule end face of installed interference fit when mounted on the shaft, the pressure should be added to the end face of the bearing inner ring; pressure should be added to the outer bearing into the bearing hole ring-side surface. Not allowed to pass through the rolling element and maintain pressure. 
 (4) for a tight fit for the inner ring, the outer ring to the bearing slide with the installation, is a type should not be separated first bearing mounted on the shaft, then the axis together with the bearing load bearing shell hole; Secretary separable, the outer ring can be installed separately. 
 (5) In order to prevent the bearing installation, tilt, installation, shaft and bearing bore centerline must coincide. Such as the installation is not correct, the need to re-install through the inner face, bearing pull out.

 A. Bearing test after installation 
 Bearing installation is correct or not, its life and a host of precision has a direct impact. If not installed properly, bearing not only vibration, noise, and low accuracy, the temperature rise increments, but also stuck to the danger of burn out; the contrary, the installation goes, not only to ensure the accuracy, life will be greatly extended. Therefore, after installation of the bearing must be tested.
