The bevel helical gearbox and the parallel shaft gearbox can be supplied with an upstream mixer flange.
With an upstream locating bearing, the bearing system is suitable for high external forces. The absorbed radial and axial
loads are transmitted to the machine via the mixer flange.
The bearings in the mixer flange are lubricated independently of their design. Initial greasing has already been carried out.
The mixer flange can be optionally supplied with an automatic regreasing device, see Regreasing intervals (Page 8). In this
case, the output-side bearing is not sealed with NILOS rings or caps.
3.2
Lubrication
In normal operating conditions and with low loads, the lubrication of the bearings is sufficient for approximately 25,000 to
30,000 operating hours.
For higher loads due to speed and / or temperature, schedule regreasing at shorter intervals.
3.2.1
Regreasing intervals
The regreasing interval is valid for a temperature of +70 °C, measured on the surface of the housing in the vicinity of the
bearing.
Note
For temperatures above +70 °C, the regreasing interval must be reduced by half for each temperature increase of 15 K.
Note
For moderate shock loading and vibration, the regreasing interval must be reduced by 20 %.
For heavy loading, the regreasing interval must be reduced by half.
Regrease the bearing after the following number of operating hours.

Roller bearing grease
NOTICE
When regreasing do not mix greases with different soap bases
For regreasing, use lithium-saponified roller bearing grease NLGI 3/2.
Using a grease gun, inject the grease into the bearing point via the lubricating nipples provided.
The grease quantities listed in the table are guide values.
