Custom bearings?
The Technical Assistance Service of Silvio Colombo S.p.A. is able to develop customized products and services both in co-design with the customer's technical department and in complete autonomy based on the customer's requests.

The Power tools are widely used in numerous types of applications. These can be divided as following described:
First of all, an high and reliable accuracy of performed work must be ensured. In this sense, the Clearance choice is fundamental, starting from the Standard ones (Normal, C2 and C3) till to Customized Clearance bands. Furthermore, ensure the absence of produced vibrations is also important.
Both Radial Load (DGBB), Axial Load (ACBB) and Combined Load solutions are available. With regard to the extent of the loads, it is also possible to have customized solutions (acting on: steel quality, number and dimensions of the balls)
Since these are machines for material machining, prevent external bodies intrusions (inside the bearing) rapresent another aspect to take care. Such intrusions can limit the effective bearing life and also preclude the optimal functionality of the finished tool. In this sense, it is crucial to adopt an efficient sealing labyrinth, capable to create the most adverse path to foreign bodies.
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.
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.
