LUBRICANTION

Lubrication

As bearings in KML bearing units have sufficient high-grade grease sealed in at the time of manufacture, there is

no need for replenishment while in use. The amount of grease necessary for lubrication is, in general, very small.

With the bearing units, the amount of grease occupies about a half to a third of the space inside the bearing.

Re-greasing

The performance of a bearing is greatly influenced by the quality of grease. In order to avoid over-filling,

it is advisable to replenish the grease while the machine is in operation. Continue to insert grsase until a little

oozes out from between the outer ring raceway and the periphery of the slinger, for optimum performance.

Although bearing units are relubricable, grease relubrication is not always required according to operating condition.

where environments are clean and operating temperature does not rise high, supplemeng of the grease

may not be required like ordinarybearings, however, the grease becomes deteriorated in any operating condition

and regular relubrication is necessarily required where operating congdition is humid or rise of temperature is high.
