Product Features
Features of idler for round belt
Feature 1: Idlers for round belts can be classified into standard type, threaded type and duplex type. The standard type and threaded type can also be divided into 2 types: narrow type and wide type.
Feature 2: Threaded idler is a product with threaded bearing, thus reducing the number of parts.
Feature 3: Duplex idler is suitable for use when belts are installed in a staggered pattern.
Example of Use
Example of use of a round belt conveyor for transporting light objects
Equipment name: round belt conveyor

Feature 1: Round belt, pulley and idler are combined for transporting thin plates and other lightweight items.
Feature 2: Idlers are configured at equal intervals to prevent bending of the round belt.
Feature 3: Urethane round belts with excellent wear and oil resistance are selected for transporting lightweight items.
Feature 4: The conveyor frame consists of 2 each of aluminium frames and machined parts.
Feature 5: Conveyor construction can be flipped over for forward and reverse use.
