Extended Bearing Pins
Extended bearing pins, one side of the chain, can be supplied hard, soft or drilled and are similar to the spigot pin arrangement.
Holed Link Plates
Single holing is primarily for use with spigot pins and is required on both sides of the chain. Double holing is provided for the assembly of special attachments on one or both sides of the chain. The holes in the inner plates are countersunk on the inside face to prevent the bolt heads fouling the sprocket teeth.
Outboard Rollers - For use on Hollow Bearing Pin Chain
Outboard rollers have two principal advantage; as direct load carriers they enable the chain rollers to be used solely for gearing purposes and in the event of outboard roller wear, they can be replaced easily without recourse to chain replacement.
They are particularly useful when attachment chain prevent the gearing rollers running on support tracks on the return run or where the roller loading is high.
