CONTI SYNCHRODRIVE N10 Polyurethane Open-Ended Nubbed Belts
CONTI SYNCHRODRIVE N10 (Nubbed) belts are polyurethane open-ended belts.
This is a very special type of belt, which does not have classic teeth like other timing belts, but has cylindrical protrusions offset alternately by half the pitch.
The pulley must have the same shape so that the protrusions fit exactly into it. This ensures synchronous operation and, in addition, the self-tracking of the belt. Inside the belt, there are again steel tension member, in special cases kevlar or stainless steel. The open-ended belts can also be heat welded into endless belts.

Belts Construction

- Polyurethane nubs (fabric cover on teeth upon request)
- Tension member/steel cord
- Polyurethane backing (fabric cover on backing upon request)
Belts Fields of Use
The belts are used in special applications where the self-guiding property of the belt drive and the low pulley width are required and when pulleys with flanges cannot be used.
The belts also reduce vibrations generated by the so-called polygon effect.
Belts Characteristics
- High transmitted power and long service life
- Self-conducting properties
- Resistant to oil, petrol, benzene, UV radiation and ozone
- Abrasion resistance
- Maintenance-free
- Temperature range, depending on application, from -30 °C to +80 °C

Optional Belt Surface Layers
The choice of the surface layer depends on the type of machine, the ambient temperature, the size of the pulleys, etc. Specifying the surface layer is determined by the material and the thickness of the layer.
| Layer Name | Material | Layer Illustration |
|---|---|---|
| PAZ (NFT) - nylon fabric on teeth Low coefficient of friction |
Nylon | ![]() |
| PAR (NFB) - nylon fabric on back Surface protection |
Nylon | ![]() |
| PAZ + PAR (NFT + NFB) - fabric on teeth and back Low coefficient of friction and surface protection |
