FAQ

Lubrication Performance Requirement

Lubrication selections are mainly according to loading, temperature, vibration and working environment etc. Additional considerations should also be taken into account:

Good performance on high and low temperature range, preferably waterproof.

Operating temperature should be 20ºC higher than the bearing working temperature.

Good performance in extreme pressure situations, in addition to antiwear properties.

Where bearings adopted a centralized lubrication system, then it is important to ensure consistency within the system, so as to maintain a smooth flow of lubricant at any time.

Commonly used grease for slewing bearings included Calcium based grease, Lithium based grease, and Aluminum based grease etc.

 

Lubrication Period

The slewing bearing's lubrication intervals are dependent on the working condition and environment in addition to the run time. Some recommendations are detailed below:

 

Generally lubrication maintenance should be performed every 150 hours. If under extreme working conditions then this period should be reduced to 50~100 hours. (Typical extreme conditions are high moisture conditions,high temperature,dusty environment, etc)

If the bearing is scheduled to be out of service for a long period of time, then the bearing needs to be filled with lubricant.

 

Lubrication Methods

Grease should be injected from the respective lubrication holes (the greasing points are generally a screwed hole with the size of M10×1 plug). After greasing slowly turn the bearing so as to ensure that the grease is distributed evenly.

If there are no special greasing requests then grease should be inserted within the bearing until grease leaks out from the sealing lip in an even manner.

The lubricating hole can be used as the intake point or the extract point. When re-lubricating the old grease should be purged out by new grease that is being injected.

After re-lubrication ensure that lubrication plug is placed back into the grease point. (For individual lubrication point)
