In general, engineering chains are slightly different from roller chains. Roller chains often are used for power transmission and engineering chains are used for material handling. There are some differences in construction between the two types of chains, so it is important to ensure that you select the correct one for your needs. Rollers are not often needed on material handling chains, but are a required part for power transmission chains. Running at high speeds is safer when you’re using a roller chain, while engineering chains are stronger for more durable and long-term operations as they have a shorter distance between sprockets.
