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.
Bearings for
HVAC applications
- DGBB Normal Series
- DGBB Thin Series
- DGBB Electric Motor Quality
- DGBB with eccentric inner ring and fixing collar
- DGBB with metallic support (tipically galvanized steel or cast iron)
HVAC (Heating, Ventilation, Air Conditioning)
Typically, applications in this sector have specific conditions such as:
- Umbalanced Impeller;
- Shaft axial pulsations;
- Environmental conditions;
- IP test approval;
- Avoid eddy currents;
- ERP requirements satisfaction (low absorption and energy consumption).
ERP Energy Related Products
Limit the energy consumption became increasingly important according with recent European Directives.
A product designed to achieve low energy consumption must necessarily guarantee high silence together with low vibrations: these represent, in fact, energy losses that are no longer acceptable (in an increasingly competitive market). It is possible to achieve low energy consumption only by having clear the technical parameters on which to intervene.
ERP project
ERP project aims to offer expertise of a reliable partner able to understand the challenges and needs of HVAC world, supplying customized solutions in line with ERP standards.
Research, Developments and Production towards a sustainable development system is our mission.
HVAC bearings
HVAC bearings are the forerunner and key player of ERP project, focalized to the efficienty in terms of Quality and consuption, totally committed to the environmental sustainability design.
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. Optimized design of cages and rolling elements;
6. Extremely refined lubricating greases to reduce startinng and running torque;
7. No contacts and high contact rubber seals with customizable lips and grooves;
8. Low levels of noise and vibrations;
9. Maximum rotation speed;
Our Challenges
1. Heavy Duty Environments
- High temperatures;
- Dust and smoke;
- Water and humidity;
2. Energy Saving
- Minimum absorbed currents;
- MAX RPM;
- Declared efficiency.
