Please use a plastic hammer to find the level and tap it evenly in the circumferential direction, and install it little by little. Until you can confirm the contact surface is fully seated by sound.  (3) Installation method of side compression flange  1.  After placing the side compression flange in position, place it in the circumferential direction. Shake back a few times to adjust the position of the mounting bolts. 2.  Install the compression bolt, and make sure that there is no deviation due to the bolt hole when tightening the bolt by hand. The distance causes the bolts to be difficult to screw in. 3.  The tightening of the compression bolt can be divided into 3-4 parts from temporary tightening to final tightening stage, repeat the tightening in the order on the diagonal. When tightening is divided into two parts When tightening the inner or outer ring press bolts, the integral outer ring is often tightened during the tightening process. Or the inner ring can be adjusted and rotated a little to make the outer ring divided into two parts or the deviation of the inner ring is corrected.  Special design: If you need special structure (such as outer ring with mounting holes, inner ring without holes, etc.), non-standard size, special materials or high precision requirements, etc., please contact.    Certifications Technological Support28 professional mechanical engineers16 professional bearing analysis engineers326 professional workers83 sets of high precision CNC machine tools32 sets of bearing testing equipment13,000 square meters factory  After Sales ServiceIn the sales process, we will have professional sales personnel to answer customers' questions in time, update the production progress, sort out the photos and videos of packaging and delivery, provide customers with the required documents; We will a
