Process Composite materials Bearing/Sleeve

Composite bearings consist of sliding layers made of polymers such as polytetrafluoroethylene (PTFE). Effectively solve the vibration and noise of the steering wheel of the car when the car is driving. During installation, composite bearings help compensate for mating component tolerances, without the need for expensive precision ground surfaces on the shaft.

Workpiece: Composite bearing/sleeve

Materials: High Hardness Composite Materials

Selected Insert: CDW010 VCGW 160408

CDW010 is made of general-purpose PCD Grade, which takes into account good toughness and high wear resistance; if you need better wear resistance, you can choose CDW025 and CDW302 materials, which have good edge strength and edge quality.
