The difference between face to face and back to back angular contact bearings, mechanical characteristics of this issue should be part of "bearing suits or anti-loaded" questions when the angular contact bearings two small end to the inside part of the anti-loaded "back to back" two small side out for dress "face to face "back to back installation withstand maximum torque load and load-aligning ball bearings 2310, axial positioning is best; face to face with a certain degree of axial clearance, load bearing small, almost no use. Currently the most used is mounted back to back. Face to face, depending on how the installation according to the theory of mechanics can be calculated radial load and axial load in accordance axis has to traverse trend which side to determine which "relax," "pinch" "Relax end" of the axial force only derive its own force "pressing end" of the axial force was removed by force itself derived axial force outside the rest of the axial force of algebra and 6, a fixed bearing rear cross toggle stick, check the bearing is worn loose; 7, loose serious rotation noise is too large, there is a serious defect FAG Bearings should be eliminated aligning ball bearings 1309K, in lieu of the same model; 8, take a bucket of the appropriate amount of grease (high quality dry yellow oil) with a slow fire to melt (not hot) , detected through the bearing into the bucket to soak no bubbles overflow. Cool down before removing the bearing grease injection molding machine bearings 51222, less residual grease. After cooling remove grease angular contact ball bearings, grease residue quantity. Determine how much grease residues required. 9, wipe with a soft cloth or tissue paper bearing grease outside the FAG bearing assembly onto the pulley undisturbed security, maintenance work is completed.
