Lubrication points are located on the drive and non-drive end of the motor. Grease escape (grease drain hole, grease trap, grease relief port) is important. Bearings will overheat if grease cannot escape or if grease traps are filled up with used grease.
During manual lubrication, the grease is applied in uneven amounts. A large quantity of lubricant is introduced at one time. This leads to temporary over-lubrication of the bearings. Non-adherence to re-lubrication intervals leads to lubricant starvation.
- Overheating of bearings and fire hazard, since distribution of excess grease takes hours; shut-off by temperature monitoring
- Bearing damage from lubricant starvation results in unscheduled machine downtimes and higher production costs
- Increased maintenance costs caused by premature wear
Re-lubrication during running operation (manufacturer recommendation) puts workers in danger. Increased accident risk due to time spent in dangerous or difficult-to-access areas.
- High accident risk
Motor shut-down when entering dangerous areas
Advantages of automatic lubrication
Re-lubrication running operation minimizes overheating of bearings
Predictable exchange intervals with reduced material and personnel expenditure
Increased workplace safety due to automatic lubrication of hard-to-reach lubrication points
Precise lubricant discharge lowers lubricant consumption and thereby environmental impact
Direct mounting on the lubrication point:
e.g. perma CLASSIC / FUTURA / FLEX / NOVA
- Easy, quick mounting
- For lubrication points with little vibration / shocks
- For easy-to-reach, safe lubrication points
Remote mounting to the lubrication point:
e.g. perma STAR VARIO
- For lubrication points with strong vibration / shocks (isolation of lubrication system)
- When workers’ safety is at risk: Mounting in safe areas
- For hard-to-reach lubrication points
Electric motors are used for a variety of applications where they convert electricity into mechanical energy. Efficient lubrication and maintenance practices are essential for reliable operation of electric motors. Many motors are located poorly accessible locations or in dangerous areas. They are therefore often only lubricated irregularly. Failure to adhere to manufacturer specifications frequently leads to damage and failures due to over-lubrication or lubrication starvation.
