BEARING SYSTEM LUBRICATION
Your motor is equpped with double-shielded ball bearings* having sufficient grease to last indefinitely under normal
service. Where the motor is used constantly in dirty, wet or corrosive atmospheres, it is advisable to add one quarter
ounce of grease per bearing every three months. Use a good quality rust inhibited polyurea based grease, such as
Chevron SRI.
*
The bearings opposite the shaft extension and on the 143T, 145T and 284T thru 445T frame TEFC
motors are double sealed. These maintenance free bearings have no regreasing provisions and need no additional
lubrication throughout the life of the motor.
When greasing the bearings, keep all dirt out of the area. Wipe the fittings completely clean and use clean equipment.
More bearing failures are caused by dirt introduced during greasing than from insufficient grease.
