Aluminium Grinding Wheel Bore Adaptor Bushing

Description

The GW140 is an aluminium reducing bushing used to adapt a grinding wheel with a larger bore to fit a grinder spindle with a smaller diameter. In moulder knife grinding setups, the bore of available replacement wheels may not always match the grinder spindle precisely — a reducing bushing bridges that gap and allows the wheel to run true on the correct spindle size. Aluminium construction keeps the bushing lightweight and easy to machine if adjustments are needed. Proper wheel fitment is critical: a loose or improperly fitted wheel is a safety and precision issue in a knife grinding environment. Verify the specific inner and outer dimensions of the GW140 bushing with Schmidt to confirm it matches the spindle and wheel bore combination in your grinder setup.
