The day-to-day maintenance of the bearings - lubrication is maintained: to reduce friction and wear. Bearings under normal operating conditions. Impossible to removal for maintenance. Therefore ensure that the bearing lubrication bearing routine maintenance work. The rolling bearing lubrication to reduce the the bearings internal friction and wear. Prevent sticking, lubrication utility as follows:
a discharge frictional heat, cooling: cycle oiling method or the like can be oil discharge the heat generated by the friction. Or coming from external heat. Cooling. Prevent bearing overheating. Prevent lubricant own aging. Another bearing lubrication can also prevent the intrusion of foreign matter into the the bearing internal, or prevent rust, corrosion, etc..
should often universal joint cross bearing lubrication, bearing different seasons, using grease is not the same as summer should be injected into the lithium grease No.3, Winter inject II lithium grease.
c, to reduce friction and wear: constituting the bearing rings, rolling elements and a retainer of mutual contact locally. To prevent the metal contacts.
d, fatigue life: bearing rolling contact fatigue life, rotation, good lubrication of the rolling contact surface, the extension. Conversely, a low viscosity oil. Lubricant film thickness is not good, is shortened.
