Bearing units "Agri-Hub"
Bearing units for use in agricultural equipment for soil cultivation must meet special requirements.
On the one hand, there are environmental conditions such as moisture, dust, and corrosive fertilizers. On the other hand, the bearing units are subjected to mechanical stress, such as collision with stones and the effect of the soil texture for the unit. In addition, high to very high axial forces generally occur, which are due to the arrangement of the attached devices.
The technical requirements are defined as such:
- Tractor speeds between 5 and 20 km/h
- Disc speeds between 90 and 350 rpm
- Force absorption of max. 3kN at the top of the disc
- Disc diameter between 300 and 800 mm
- Temperatures between -20° and +50° C
The solution
The technicians at NBR have developed
- maintenance-free, integral bearing unit which is sealed,
- lubricated for service life and
- achieves high rigidity through integrated angular ball bearings.
Compared to most other types, the EBS Agri-Hub bearing has an additional seal under the cover. All seals of the EBS Agri-Hub are made of a special FPM base VRS (Viton) material, which provides a high level of resistance against the environmental influences associated with agricultural soil cultivation (even manure)
The advantages of the EBS Agri-Hub
The advantages of the EBS Agri-Hub
- Easy to assemble
- Improved sealing against dirt and moisture
- Corrosion-resistant through zinc-coated housing (Cr VI free)
- Improved environmental compatibility (no grease leaks)
- Prevents cords from winding around the unit through shape of the housing
- Protective cover and additional seal for disc replacement
- Cost reduction during warranty, inspection and assembly
- improved machine reliability due to increased product quality/reliability
