Motor Installation And Maintenance Instructions

1 Motors with Oil-Lubricated bearings must be mounted on a level surface to prevent oil leakage and for proper operation of the oil sight glass 2 The motor base should be bolted down square with the pump head and at right angles with the pump shaft Bolt the motor to the pump head using bolts of the largest size permitted by the clearance

Top 5 best lubricants for electric fan motor in 2019

To assist you with the lubrication of your electric fan needs we have compiled reviews on the top five lubricants on the market for electric fan motors below They should help you narrow your options down to the right lubricant that best suits your situation

Relubrication

Compare this with the average electric motor bearing Its shaft diameter is twice that of the boat trailer axle The electric motor bearing rotates at twice or even four times the speed and we expect the bearing to last 24 000 hours—three or more years Packing the motor bearing full of grease would create excess heat and reduce bearing life

Best Practices Using Grease Electric Motor Preventive

Best Practices for Using Grease for Bearing Lubrication The best way to reduce your need for electric motor service is to protect the bearings of your electric motors and one of the easiest ways to do this is to make sure that the bearings for that motor are always adequately lubricated Most electric motor bearings use grease for lubrication (although some use lubricating oil)
