Polymer block chain<br />
<strong>Renold</strong> Polymer Block <strong>Chain</strong> (Rubber Block<br />
<strong>Chain</strong>) has been specifically designed for use<br />
in the feed, conveying and on work discharge<br />
types of applications, where an undamaged<br />
surface finish is an essential requirement for<br />
your finished product.<br />
<strong>Renold</strong> <strong>Chain</strong> has been running successfully in<br />
all types of machinery and sectors of industry.<br />
Examples being:<br />
• Woodworking<br />
• Furniture Industry<br />
• Profile Grinding<br />
• Book Binding<br />
• Conveying Plastic Tubes<br />
• Glass Handling<br />
• Cable Management<br />
• Conveying of Fragile Components<br />
The chain is based on ISO, DIN and ANSI<br />
standard, both Simplex and Duplex, the only<br />
difference being the overall pin length. Polymer<br />
block chain can be used in many different<br />
environments by simply changing the block<br />
material. The most popular chain in this<br />
catalogue being available from stock.<br />
The polymer block vulcanised onto the U-plate<br />
is wear resistant and has a shore hardness of<br />
50 to 60. It is suitable for working temperatures<br />
up to a maximum of 80°C (176°F).<br />
• Polymer block chain is only supplied in even<br />
pitch lengths, including a connecting link<br />
• <strong>Chain</strong> can be supplied without polymer<br />
blocks, with the standard U-plates fitted<br />
to the outer links<br />
• For a small extra charge chain can be zinc<br />
plated, but this will reduce the minimum<br />
breaking load of the chain by 10%<br />
• The gearing dimensions of polymer block<br />
chain allows them to run on standard sprockets<br />
Other sizes of chain and block materials can<br />
be supplied, apart from the popular and made<br />
to order chain detailed in this catalogue. For<br />
special applications <strong>Renold</strong> multiplex chain,<br />
up to sextuplex, have been supplied and used<br />
successfully where a wider polymer block<br />
platform is required.<br />
