KOYO bearings should be cleaned before installation. Installation, you should use special tools and auxiliary bearing pressed into the straight and evenly, not hand-hammer percussion, especially the ban on direct percussion in the rolling mill bearings. When the bearing ring and bore with loose bore shall repair or replace the bearings, not to play in the bearings with surface pitting or pad copper reluctant to use. Rolling mill bearing Demolition should pull the bearing to pull out, do not use chisels, hand hammer, tap bearing.
1. To the axis installation KOYO bearings, you must unplug the pins bearing jacket, at the same time the journal surface is polished smooth and clean, painted, oil anti-rust and lubrication in a journal at (allowing bearing slightly rotating the shaft).
2. Lubricant in the bearing and the bearing with the topcoat, bearing into the bearing. Then assembled rolling mill bearings and bearing with sleeve on the shaft. Pushed to the desired location for installation.
3. Fixed bearing, do not tighten bolts make KOYO bearing jacket can rotate within the bearing. Also installed with the other end of a shaft bearing and seat, the axis of rotation a few times, so that the mill bearing itself automatically to find the positive position. Then the bearing bolt.
4. Mounted eccentric the condom. The first eccentric condom in the rolling mill bearing on the sets of eccentric steps, and tighten by hand along the axis of rotation direction. Then the small iron bar to insert or to withstand the eccentric sleeve counterbore. The direction of rotation of the hammer along the axis by hand to tap the small iron bar.
The eccentric sleeve is securely installed, the final locking eccentric sleeve socket head cap screws.
KOYO bearings, lubricant oils and greases. When the shaft peripheral speed is less than 4-5m / s, or parts of the car can not be used lubricating oil, grease lubrication. Grease lubrication of the advantages of simple sealing structure, the grease is not easy to drain, affected by temperature, little, add a grease you can use a longer time.
Normal mill bearing operation sound should be uniform, smooth and not harsh voice, rather than the normal KOYO bearings running sound all kinds of intermittent shock or harsh sound. First to get used to the normal operation of the bearing sound, and then be able to grasp the judgment is not normal bearing operation sound, and then through the accumulation of practical experience, further analysis of what is not normal sound corresponds to what bearing irregularities. KOYO bearings of the type of abnormal sound is difficult to explain in words, depends mainly on the accumulation of experience.
