suministro de grasa

NSAR ball bearing units are supplied with high quality grease packed inside a high quality seal.Therefore,under clean operating conditions at lighter loads and lower speeds at normal temperatures,the bearing may be used with no further lubrication.
However,under harsher operating conditions and environment,the grease will deteriorate much more rapidly.This would include environments exposed to dust,moisture or higher operating temperatures.in such cases,a regreasing schedule must be established to prevent premature failure of the bearings.
The life of the bearing can be greatly extended by proper attention to the regreasing schedule and by supply-ing the proper amount of grease.Please note that too much grease can be detrimental as well as too little grease.

cantidad de grasa

The amount of grease initially supplied in a NSAR Ball Bearing Unit is approximately 30 to 35% of the internal space capacity of the bearing.
lf the bearing is ever over greased, the agitation of the grease causes internal friction and heating of the bearing.
The first sign of failure will be excessive grease finding its way to the outside of the bearing. Do NOT exceed the initial greasing amount.
