To ensure the steady conveying of goods, the principles of selecting the correct roller pitch (roller centre distance, indicated by T) is a minimum 3 rollers to support the goods at any moment, i.e. T≤1/3L.
- Products that require steady conveying, use T = 1/4 ~ 1/5 L or smaller.
- For flexible, long and thin products, you need to check the deflection of the product. The product deflection should be less than 1/500 of the roller pitch otherwise it will greatly increase the running resistance.
- The pitch of double sprocket conveyors must be calculated in multiples of 1/2 the chain pitch.
- The pitch of poly-vee rollers is limited by the type of poly-vee roller.
