CONTI SYNCHRORIB Double-Sided Combined Belts
CONTI SYNCHRORIB are combined double-sided drive belts. One side consists of a timing belt (SYNCHRO), the other of a poly-V-belt (RIB). The timing belt ensures precise synchronous movement, and the ribbed side allows some minor slippage under shock loading.
The toothed side of the belts can be in HTD or STD profile. Depending on the power to be transmitted, they are available with glass cord tension member (STANDARD and CXP), or with aramid tension member (CXA). The ribbed belt side is in PK profile with a rib spacing of 3.56 mm. These are very special belts, produced in only a few specific lengths and widths, which are determined by the number of ribs.
Antistatic – for compliance with requirements to ISO 9563. 
The trendsetters with less polycyclic aromatic hydrocarbons (PAH) for clean operation and protection of persons in case of long-term contact with the belt.

Belts Construction
- Polyamide fabric
- Synthetic rubber teeth
- Glass cord tension member for STANDARD or CXP (aramid tension member for CXA)
- Synthetic rubber ribs
Belts Fields of Use
CONTI SYNCHRORIB belts have been specifically developed for driving mill table rollers. These rollers, which are grinding elements, rotate against each other at varying circumferential speeds.
These combined drive belts serve as an excellent alternative to double-sided timing belts, which are not only costly but also more susceptible to damage due to overloading and uneven loading.
Mill tables are primarily designed for grinding dry bulk materials. While they are mainly used for grinding grain in mills and feedstuffs, they can also be utilized for grinding corn, rice, chalk, certain spices, and chemical products, as well as for waste cleaning.

Notice
General factory certificates are not sufficient for belts used in potentially explosive atmospheres.
If a test report according to ISO 1813 and ISO 9563 is required for the application, it is necessary to inform us of the request for delivery of belts including the certificate when ordering them (when ordering belts via Eshop, please write this request in the "Note" field before by sending the order). The certificate is issued by ContiTech after the test in the production plant.
