Hobby & Bricolage (garden care, cleaning, maintenance, etc.)
Hobby & Bricolage products are widely used in numerous types of applications, which can be divided:
- for professional or hobby use;
- by size of machinery (based on the flowers, plants, gardens, etc. to be worked on);
- for necessary power supply: battery (low power) or wired to the power line.
Typical machines of this sector can be:
- hydro-cleaners
- Lawn mower
- trimmers
- motor mowers
- wire brushcutters
- special machines for grass cutting
- mowing tractors
Accuracy of the work performed
Starting from Normal Clearance, both Standard solutions with C2 and C3 clearance and Customized Radial Clearance range are available, in order to allow high precision and control of the machining.
Types of Applied Loads and Choice of Bearing
Many types of bearings are available that can meet different needs: starting from solutions for Radial Load (DGBB) and Axial Load (ACBB), up to rod ends and spherical plain bearings, ideal for their adjustability and easily assembling.
Useful life and protection from external contaminants
A crucial aspect is the bearing life and, consequently, the protection from external contaminants. It is therefore crucial to adopt an effective sealing labyrinth, capable of creating the most adverse path to external bodies.
Key requirements
1. Super pure 100Cr6 steel to increase bearing life;
2. Super-finish to reduce surface roughness;
3. Fine grinding to obtain P5 or P4 tolerances on the raceways;
4. G10 grade balls to reduce friction;
5. Ultrasonic cleaning combined with demagnetization treatment;
6. Lubricating greases extremely suitable for increasing the useful life of the bearing;
7. Different seal design: no contact, with one or more sealing lips;
8. 100% control of noise and vibrations, along the production process;
Our challenges
1. Minimum Vibrations for Maximum Accuracy
- High machinering execution;
- Lubricated injected in a clean environment;
- 100% selection at the end of the line;
2. Control Standards Implemented
- Automatic production line;
- Dedicated control grid;
- Storage and record of production highlights.
