Taper Bored/Brushed



This stock range of Simple & Duplex Pilot Bore Sprockets and Simpler Taper Bored with Induction Harden Teeth to min HRC45 to Max HRC55 are designed to cater for the chain drives with a gearing ratio of more that 1:1, where the smaller drive sprocket is rotating at a higher speed and is therefore in more contact with the harden roller and in turn presents more wear or for any application where excessive wear is undesirable.



In addition to this stock range we can provide a Flame Hardening Service to any of the standard stock range sizes that are produced from C45 Carbon Streel (Price and availability on request).



These sprockets can be machined to fulfil any of the following criteria:




To suit an imperial shaft size.



To suit a metric shaft size not listed in the standard shaft ready pre-machined range.



To suite a customer's own requirements.
