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 intake quantity is between 1
and 1.5 l/min with an oil pressure of approx. 1.5 bar. The images of the selector gearbox
(see below) show the approximate oil intake and outlet positions on the gearbox. The precise
dimensions can be taken from the relevant mounting drawings.
For the following gearboxes, circulating oil lubrication is required for V1 or V3 vertical
mounting positions:
● Gearbox 2K120
● Gearbox 2K121
● Gearbox 2K250
● Gearbox 2K300
