Here at SprocketsNZ we manufacture and import a wide range of American standard, British standard, timber and speciality sprockets.  From 25mm through to 1.6meters OD.
  • Our imported sprockets include a range of simplex, duplex and triplex pilot bored.  These come in both American or British standard in 1045 material.  Common stock levels range from 8 tooth through to 114 tooth.  - please see specification sheets below.
  • A vast range of our imported sprockets have induction hardened teeth which give the sprockets a better life expectancy.  If we do not stock these with IHT we have the capabilities in store to flame harden the teeth. 
  • Sprockets that are bored and keyed, machined for bearing or locking bush are one of our day to day expertise.  If you are after a machined sprocket these can often be done in a day or two. 
  • Split sprockets for an easier fit in difficult applications.  Having two sprockets split in half for a easy installation.  These are usually supplied for 81X or WH78 chains however we also manufacture a range of transmission roller chain split sprockets.

  • Double simplex or combo sprockets are specifically manufactured to suit each machines requirements.  These are often used to run two simplex roller chains often in different directions.  With a combo sprocket these are not always the same pitch chain and we will often manufacture sprockets with two completely different OD sprockets.
  • Conveyor chain sprockets are profile cut out to suit different pound chains.  Every sprocket is specific to machine requirements and are all made to order.  Common sizes are to suit 3"P, 4"P, 6"P, 8"P, and 81X.
