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 fi lled up with old grease.
During manual lubrication, the grease is applied in uneven amounts. Too much lubricant at one time causes temporary overgreasing. Long relubrication intervals lead to lubricant starvation.
Excess grease takes hours to be distributed in the bearing: Bearing heating / fire hazard; Shut-off by temperature control
Bearing damage from lubricant starvation results in unscheduled equipment downtimes and higher production costs
Increased maintenance costs caused by premature wear
Relubrication on running motors (recommended by motor manufacturers) puts workers in danger. Maintenance work in dangerous and hard-to-reach places increases the risk for workplace accidents.
- High risk of work-related injuries
Motor shut-down required when entering dangerous areas
Advantages of automatic lubrication
Relubrication while the motor is running minimizes bearing heating
Projectable service runs reduce material and staff costs
Increased workplace safety through automatic lubrication of
lubrication points that are difficult to access
Precise lubricant discharge reduces lubricant consumption and environmental impact
Direct mounting on the lubrication point:
e.g. perma NOVA
- Easy, quick mounting
- For lube-points with little vibration / shocks
- For easy-to-access and safe lubrication points
Remote mounting to the lubrication point:
e.g. perma STAR VARIO
- For lube-points with strong vibration / shocks (isolation of lubrication system)
- When workers’ safety is at risk: Mounting in safe areas
- For hard-to-access lubrication points
Electric motors are used for a variety of applications where they convert electricity into motion. Efficient lubrication and maintenance practices are essential for the reliability of electric motors.
Many motors are located in hard-to-reach or dangerous areas and are not lubricated according to manufacturer specifications. Overgreasing and lubricant starvation are the major causes for bearing damage and electric motor failures.
