Stainless steel bushes are crucial for the optimal operation of any wheel application. Because of this, if it is missing, there will be a lot of friction in the wheel's bore, which will quickly wear it out and shorten its lifespan. This is actually crucial for industrial wheels, such as metal wheels at timber mills or manufacturing facilities, that must carry heavy weights. An excellent bearing and gear grease are required to lubricate stainless bushes. The greatest stainless steel bushes are provided by AZTECH INNOVATIONS. Our specifically designed CNC bushes have a Rockwell hardness of 60HRC and are composed of the stainless steel grade 440. These are constructed 02 of a millimeter larger than necessary to enable a tight fit without the need to apply excessive pressure, which could deform the gearbox.
