Maintenance of Bearing

Application and Maintenance

1)Inspection of mounting bolts an abnormal appearance

After bearing rotation 100 hours,check pre-tighten torque of inner ring and out ring, then once 500 hours inspection.

2) if coming noise.impact,electric current increasing suddenly in application .stop machine to disport and get rid of trouble,if necessary,inspect by removing.

3) After mounting bearings.fill in dedicating grease as user's requirements.if necessary to ask the maker,filling grease while rotation,grease equally spaced until grease spills over sealing lips.Once 100 hours filling

later,filling grease period should be short at high temperature and dusty condition.

4) Gear surface should clear sundries every 10 days and bearing gear lubrication,User can personally select the finest grease due to combined working elements.Recommendatory grease as table 7-1.

5)Avoid direct sunlight on slewing bearings while usage,can not directly wash bearing with water to avoid water into raceway,avoid hard forcibly eye-winker access or ingress tooth meshing area.

6) Often check sealing,in case seals aging,damaged,change seals timely,In case fall off,reposition timely.
