Balling
Another important phase of the work in the fields is the packing of the harvest, for example hay, in order to create round or square bales that allow easy storage and transport.
The creation of bales is another aspect of primary importance for the conservation of the product itself.
Some key parameters are the followings:
- Moisture content suitable for long storage;
- Bale format (round or square);
- Bale weight, variable from about 30 kg up to 630 kg.
Loads Types and Bearing Choice
Many types of bearings are available that can meet different needs: guided rollers with convex outer ring (ideal for consistent radial loads), passing through special bearings with hexagonal hole and self-aligning supports, up to Cam-Followers (wheels ) able of withstanding very high radial loads and also axial loads deriving from misalignment.
Seals resistant to the infiltration of dust and mud
Environmental exposure governs the useful life of these applications. The efficiency of the sealing is a crucial aspect to prevent the intrusion of contaminants. Specific dust and mud infiltration tests allow to optimize the design of the sealing system, respectively realized by the rubber seals and by the grooves on the rings (different shapes and complexity of execution).
Key requirements
1. Technical Analysis & Feasibility, for passing Approval on Final Customer Application;
2. Super pure 100Cr6 steel to increase bearing life;
3. Super-finishing to reduce surface roughness;
4. G10 grade balls to reduce friction;
5. Ultrasonic cleaning combined with demagnetization treatment;
6. Different cage materials (polyamide, steel or centrifuged brass);
7. Seals engineered to reduce external contamination;
8. Optimized lubricating grease for severe working conditions;
9. Sealing infiltration test against dust and mud;
10. Comparative Tests with similar product, standard or Customized solutions.
