Harvesting
The optimization of the harvesting procedure is certainly one of the key steps to maximize the work and the product in the fields.
The minimization of waste or products left on the ground is a fundamental aspect, in fact machineries used for harvesting are increasingly sophisticated and technological, regardless of their size and the agricultural product to be collected.
- Combine harvesters for wheat harvesting;
- Motor-mowers for hay harvesting;
- Conveyor rollers for tomato harvesting;
- Harvesters for the olive harvest.
Loads Type and Bearing Choice
Many types of bearings are available that can meet different needs: starting with DR-SRB (double row spherical roller bearings) ideal for high bidirectional radial and axial loads, passing through deep groove radial ball bearings (DGBB), up to self-aligning supports (available in various shapes and materials).
Seals resistant to the infiltration of dust and mud
Specific infiltration tests to dust and mud allow to optimize the design of the system system, respectively achieved by the rubber seals and by the grooves on the rings (different shapes and complexity of execution).
Materials, Lubrication and Temperatures
The resistance of the materials to the operating conditions is certainly an important aspect, in fact the effective life of the bearing depends on it, in terms of useful life. Numerous technical solutions are available (both Standard and Custom) able to meet the specific needs of use.
Key requirements
1. Super pure 100Cr6 steel to increase bearing life;
2. Super-finishing to reduce surface roughness;
3. Raceway design studied to create an optimized contact degree between ball and raceways;
4. G10 grade balls to reduce friction;
5. Cage in different materials (polyamide reinforced with glass fibers, steel or centrifuged brass) to better wrap the rolling elements;
6. Ultrasonic cleaning combined with demagnetization treatment;
7. Seals engineered to reduce external contamination;
8. Sealing infiltration test, with dust and mud, through the use of mixtures with prescribed particle size;
9. Optimized lubricating grease for severe working conditions.
