iwis is one of the leading suppliers of high-precision chain drive systems for industrial applications in mechanical and plant engineering, the packaging, printing and food industry and conveying handling technology. iwis' complete product range includes precision roller chains, high-performance roller chains, conveyor chains, maintenance-free and corrosion-resistant chains, accumulating conveyor chains, special conveyor chains, leaf chains, slat-band chains and plastic mat chains for industrial applications, agricultural machinery chains and accessories for the agricultural industry, as well as control drive systems for the automotive industry. Founded in 1916, the family business is now managed by the fourth generation. The iwis Group employs over 2,014 people, 250 of whom work for iwis antriebssysteme. In addition to production sites in Germany (Munich, Landsberg, Wilnsdorf and Sontra) as well as in the Czech Republic, China and the USA, there are subsidiaries in various European and non-European countries, including Brazil, England, France, India, Italy, Canada, Korea, Switzerland and South Africa. iwis is represented at 45 locations worldwide.

As well as moving loads safely and reliably, iwis leaf chains can be adapted to meet customer-specific requirements and are compliant with EC Machinery Directive 2006/42/EC. iwis link plates with optimised geometry are precision-formed, heat-treated, shot-peened and have a particularly high contact ratio. A smooth, hardened surface gives the pins added wear resistance. Thanks to the improved press-fitting of pins and outer plates, the fatigue strength of these chains is also higher.
iwis accumulation chains guarantee problem-free positioning of conveyed goods and prevent jolting almost entirely when the belt starts and stops. The idler rollers on each side serve two purposes: firstly, they engage with the sprocket teeth to transmit power, and secondly, they support the chain in the guide track.
