LUBRICATION
Slewing Ring.
Initial Grease Lubrication.
INA Slewing Rings are supplied with an initial grease lubrication of a high quality lithium complex soap base grease
KPN2N-25 (DIN 51825).
The free space in the raceway system in the bearing is filled with grease. A grease with an operating temperature
range of
-
13deg.F to
+
302deg.F(
-
25deg.C to
+
150 deg. C), is suitable.
Re-lubrication Interval.
Re-lubrication intervals are dependant on :
•
Operating conditions.
•
Environmental issues such as contamination, water etc.
•
The design of the Slewing Ring.
The re-lubrication interval can only be precisely determined by carrying out tests under operating conditions.
If comparable results are not available, the guide values shown below can be used.
Values shown are based on the following conditions:
•
Operating temperature 158deg.F (70deg.C).
•
Circumferential speed 0,5m/s.
•
Low to medium loading.
Recommended re-lubrication period.
The raceway system of a slewing ring should always be re-lubricated in the following instances :
•
After each cleaning eg. spraying with water, steam etc.
•
Before and after long stationary periods, such as inactive winter months, if high levels of moisture occur.
Grease ‘operating life’ for the raceway system.
If re-lubrication is not possible, the operating life is a decisive factor.
Experience of a large number of applications shows that guide values for the grease operating life can be taken as
twice that of the guide value for the re-lubrication interval.
At operating temperatures over 158deg. F (70deg.C), both the re-lubrication interval and the grease operating life
are reduced.
In order to ensure operational safety, the grease operating life should not exceed 3 years.
IMPORTANT
When using a pressure washer do not allow the water jet to be pointed at the Slewing Ring Seals. The high
pressure water will force dust, dirt and contaminants past the seals and into the raceway. This will result in premature
failure of the bearings in the raceway system.
Raceway System.
Re-lubrication procedure.
Contaminants such as dirt, dust, spray water and cont aminants are forced out by the re-lubrication procedure.
•
It is preferred that the same lubrication as used for the initial operation should be used for re-lubrication.
•
Re-lubrication should always be carried out while the slewing ring is warm from operation.
•
Clean the lubricating grease fittings.
•
Press grease into the lubricating grease fittings in turn, until a collar of fresh grease forms all the way around
both of the seals (turn one bearing ring slowly during this process).
•
The used grease must be able to flow out unhindered.
•
Ensure that all feed ducts are full of lubricant before returning the slewing ring to operation.
