Conveyor Pulley, Drive Pulley, Snub Pulley, Take-Up(Tail

Pulley, which is provided to increase/decrease, warp/contact angle of belt on nearby pulley, is called Snub Pulley. Take-Up(Tail) Pulley Pulley, which can be moved to keep belt tight, is called take-up Pulley.Take-Up Pulley may be a drive pulley or an idler pulley.

Snub pulleys Rubber conveyor belts Ambelt® conveyor belts

Snub pulleys are used to increase the wrap angle of the conveyor belt to reduce the pulling force of the belt. Snub pulleys can therefore optimise the cost of your conveying system, since they reduce the belt tension which means that a conveyor belt with a lower belt strength can be used for the same purpose. When using conveyor belts with a

Conveyor Overview

Snub pulleys (m) are sometimes incorporated into the design of a conveyor in order to increase the angle of wrap (n) of the belt on the drive pulley. The greater wrap angle on the pulley allows more power to be introduced into the belt as is passes around the drive pulley without slip occurring. In this way, fewer drives are needed on longer
