Hollow Bearing Pin Chain
The hollow bearing pin type chain affords ready facility for fixing attachments to outer links by bolting through the hollow bearing pins and is suitable for use in all normal conditions.
The attachments may be bolted up tight or held in the hollow bearing pin in a ´free´ manner.
Bolted attachments should only span the outer link, as a bolted attachment spanning the inner link would impair the free articulation of the chain.
