​Features

Quality Materials

​Our 2.609" pitch polymer sprockets are manufactured from high performance, super strong Northane 75D polyurethane​ that offers self-lubricating properties. The replaceable & interchangeable idler bearing inserts are also self-lubricating & are manufactured from high performance molybdenum disulfide & graphite filled 75DM polyurethane.

Save Money & Time

Split type sprockets save both money & time. They are lower cost than the equivalent split metal sprocket & dramatically reduce the time required for installation or replacement. No longer do you need to take the shaft assembly to pieces to fit a sprocket. Four simple fastener assemblies hold the sprocket in place.

Metal Sprocket Replacement

​In some cases (application dependent) our polymer sprockets manufactured from Northane 75D polyurethane outlast metal sprockets. They are light weight (1/6 weight of steel), long lasting, do not rust & offer far quieter operation. These sprockets do not require lubrication although two grease nipples are optional.

Keyed ​Drive Hub Inserts ​

Our range of drive hub inserts are replaceable, interchangeable​ & suit a variety of shaft sizes with different key sizes. Manufactured from zinc-aluminium alloy​ which offers far greater wear-ability than traditional 660 bronze bushes at reduced costs. Keyed Drive inserts suit shaft sizes 50mm, 60mm, 1 7/16", 1 15/16", 2 3/16", 2 7/16" & 2 15/16".

Idler Inserts

​For the tail end, we have a range of idler inserts manufactured from self-lubricating bearing grade 75DM polyurethane filled with molybdenum disulphide​ & graphite. Our range of idler inserts suit shaft sizes in 50mm, 60mm , 1 15/16" & 2 7/16".
