Polyamide Power Transmission Belts
Our comprehensive range of polyamide power transmission belts is well-known for its reliability and long service life in the most demanding applications and harsh conditions. Their traction layers are highly resilient and can cope with intermittent overloads, which prevents residual elongation. In addition, many of these products are known for their excellent performance as processing belts.
A Series:
The A range is specially designed for heavy open drives where a robust design with the highest endurance is required.
Main features :
• Resilient design
• Shock resistant, very forgiving
• Longitudinal grooves enable high grip
• Operating temperatures up to 100 °C / 212 °F
• Proven NBR rubber cover with high abrasion resistance
Leather Flat Belts:
Based on the proven polyamide belt A series design, with the running side covered with high-quality leather, this range incorporates all the features of top-quality belts.
Main features:
Resilient design
• Shock resistant, very forgiving
• Leather surface provides reliable grip and power transmission even in dirty conditions
S & SP Series:
S tangential belts have been market leaders for many years. Particularly in textile industry applications, the range offers advantages such as uniform spindle revolutions, no re tensioning requirements, and a long service life.
Main features:
Symmetric belt construction, suitable for double-sided power transmission
• Resilient design
• Shock resistant, very forgiving
• Good reversed bending and flex fatigue properties
• Proven NBR rubber covers with high abrasion resistance
