Renold Polymer Block Chain (Rubber Block Chain) has been
specifically designed for use in the FEED, CONVEYING and on
WORK DISCHARGE types of applications, where an undamaged
surface finish is an essential requirement for your finished product.
Renold Chain has been running successfully in all types of
machinery and sectors of industry. Examples being:
■ WOODWORKING

■ PROFILE GRINDING
■ BOOK BINDING
■ CONVEYING PLASTIC TUBES
■ GLASS HANDLING
■ CABLE MANUFACTURE
■ CONVEYING OF FRAGILE COMPONENTS
The chain is based on ISO, DIN and ANSI standard, both Simplex
and Duplex, the only difference being the overall pin length. Polymer
block chain can be used in many different environments by simply
changing the block material. The most popular chain in this
catalogue being available from stock.
The polymer block vulcanised onto the U-plate is wear resistant and
has a shore hardness of 50 to 60. It is suitable for working
temperatures up to a maximum of 80°C (176°F).
■ Polymer block chain is only supplied in even pitch lengths,
including a connecting link.
■ Chain can be supplied without polymer blocks, with the
standard U-plates fitted to the outer links.
■ For a small extra charge chain can be zinc plated, but this
will reduce the minimum breaking load of the chain by 10%.
■ The gearing dimensions of polymer block chain allows them
to run on standard sprockets.
Other sizes of chain and block materials can be supplied, apart from
the popular and made to order chain detailed in this catalogue. For
special applications Renold multiplex chain, up to sextuplex, have
been supplied and used successfully where a wider polymer block
platform is required.
