Optibelt-RBK
Ribbed Belts

     Very quiet and extremely flexible, the Optibelt ribbed belt drives equipment in many cars, commercial vehicles and buses. The ribbed belt transmits power to the turbo-charger, the power steering pump, the air conditioning compressor, and the alternator.

     Progressive reduction in the size of new engines calls for ever smaller pulley diameters and narrower spaces in which to install them. The single belt characteristic of the ribbed belt makes clever use of this restriction.

     Because of its extreme flexibility, the Optibelt ribbed belt is able to be used on serpentine drives.

Application
Use in automobile design for driving ancilliary equipment.

Application Benefits

• high power transmission, good wear resistance, quiet running
• not affected by vibration, intermittent drives or shock loading
• low stretch, excellent behaviour under tension
• very flexible, extremely small pulley diameters, serpentine drive (use of reverse idlers), good heat dissipation, long service life.
