NoTE
Do not over grease bearings. Overfilling can lead to
excessive heat and/or unseating of the seals. Add
grease slowly and under light pressure. Whenever
possible, rotate bearing slowly while lubricating.
Polyurea and lithium-based greases are not
compatible. Mixing the two grease types may lead to
premature failure.
