Circulating oil lubrication

Circulating oil lubrication is required for the following applications:
● for continuous operation
● for operation over a longer period of time in one gearbox stage
● for intermittent operation with short no-load intervals
The type of circulating oil lubrication depends on which operating temperature level is
required in use. Several applications require a low operating temperature level.
We recommend, in these cases, circulating oil lubrication.
The oil flow rate is between 1 and 1.5 l/min with an oil pressure of approx. 1.5 bar.
