What are the limits for the different conveyor chain parts?
In generally, the life of a conveyor chain is determined by the amount of wear on the individual parts. What part meets its life first is determined by the conditions of use. The wear life limit for the individual parts is as listed below. (1) R Roller / F Roller The roller has met its limit when the bottom of the plate begins to touch the rail due to wear on the contact surface or the sliding area with the bushing. If there is a curve in the rail there will be less wear allowance for only the corresponding S dimension as seen in the diagram below. Special care is needed when compared to flat conveyance. (2) S Roller When roller thickness wears to 40% (3) Bush When bush thickness wears to 40% (4) Plates • Wear will develop from abrasion between plates as well as roller and plate contact at points (A) and (B) in the below diagram. Chain strength will be insufficient when wear exceeds 1/3 of the plate’s normal thickness. • If items are conveyed directly on the plate, wear will occur agai
