Annex 4 ERW maintenance
Applies to Innergy tech Wheels installed in Geniox Units
4.1 ERW Bearing
Wheel bearings are greased before shipping, but it is recommended to grease them again before start-up. Proper care and maintenance
of the wheel bearings should allow it to last for up to twenty years.
The recommended lubrication interval is every 6 months. Innergytech recommends a NLGI grade 2 consistency,mineral oil lithium or
lithium complex base grease to be pumped into the bearing grease fitting (1/8” NPT) (1) The pillow block bolts shall be inspected where
a special seal lacquer has been factory applied (2). An inspection is required at the unit start- up and every 6 months. This is a visual aid
will warn you if the pillow block bolts or the bearings set screws have loosen over time or during transport. A seal lacquer without cracks
is the indication that bolts and screws have not loosen.
If a wheel bearing ever needs replacement, please consult Systemair for parts and instructions.

4.2 ERW Belt tensioner
The belt tensioner is fastened to an aluminum plate aligned with the wheel motor. The tensioner is installed perpendicular to the frame
with a small angle inclined away from the motor (see figure 2.23c). The motor belt will push down on the tensioner when installed. For
optimal belt tension, the final position of the tensioner should be under 45-degree angle of the wheel frame, see figure for details.
