Product description


12mm Cartridge Spline Extender Adapter - 20 Spline to 20 Spline.

This will only work with cartridges that have 20 splines which have a diameter of 7.6mm. The extender will extend the existing cartridge by 12mm (1.2cm) when fitted.

These can be stacked on top of eachother, therefore if you need to extend the cartridge by 40mm, you can use 4 of this extender.

You will also need a screw to hold the extender in place. If you use 1 extender (i.e. extending the cartridge by 10mm), you will need a 20mm screw. However long you extend the cartridge, you will need a screw which is 10mm longer than the combined total extender lengths.

The spline diameter can vary by +-0.1mm

For example, if you extend if by 60mm (i.e. 6 stacked on top of each other), you will need a 70mm screw). All related screws are the following (for cartridges that use an M4 screw): DVM4x20, DVM4x30, DVM4x40, DVM4x50, DVM4x60, DVM4x70, DVM4x80, DVM4x90, DVM4x100
