Medical & Precision tools (watchamking and laboratory equipments)
A particular field in bearings use is adopted in medical applications and precision tools (such as watchmaking, laboratory equipment, etc ...). Specific features for these types are:
- High precision (for the tool tip);
- High and very high rotation speeds;
- Absence of Vibrations;
- Smooth and controlled movement.
Inner Geometries Design and Vibrations
Since high precision is required for these appliances (as per example: Dentist or Goldsmith hand tool) it is clear that a specific design, able to allow the movement without producing annoying vibrations, is needed. Otherwise, it could be capable of compromise the expected results.
Raceways Roughness and Superfinishing
Another important aspect, as mentioned, is the achievement of remarkable rotation speeds.
For this purpose, high machinering execution must, necessarily, through a strict control along the (automatic) production line.
Standard Radial Clearances and Customized Clearances
Starting from Normal Radial Clearance, both solutions with C2 and C3 Radial Clearance are available, including Customized bands with tight clearance. This to allow elevate precision and motion control.
Key features
1. Super pure 100Cr6 steels to increase the bearing life;
2. Superfinishing to reduce surface roughness;
3. Fine grinding to obtain P5 tollerances on the raceways;
4. G10 grade balls to reduce the friction;
5. Ultrasonic washing combined with demagnetization process;
6. Extremely refined lubricating greases to reduce startinng and running torque;
7. No friction rubber seals, equipped with 1 or more lips;
8. 100% Noise and Vibrations inspection, along the production line;
9. Maximum starting at the minimum rotation speed.
Our Challenges
1. Minimum Vibration for Maximum Precision
- High machinering execution;
- Lubricant injected in a clean environment;
- 100% selection at the end of the line;
2. Implemented Inspections as per Standard
- Automatic production line;
- Dedicated checking list;
- Storage and record of production highlights.
