Rulon Bearings

Lehvoss LUVOCOM® 50/CF/10/GF/10/TF/10/BK Polycarbonate with carbon fiber, glass fiber and PTFE  (discontinued **)
Categories: Polymer; Thermoplastic; Polycarbonate (PC); Polycarbonate, Carbon + Glass Fiber Reinforced

Material Notes: Properties/attributes include: Very strong and stiff parts; low coefficient of thermal expansion. Electrically conductive, suitable for continuous discharging of statically-generated electricity. Improved friction and wear behavior. Emergency (dry) running property. High dimensionally stable precision parts, even at elevated temperatures and narrow tolerance range.

Data processing machinery, precision engineering, film and photo industry, sporting and leisure goods, medical engineering. Typical uses include: Body and duty parts in office equipment, gear wheels, grippers.

Processing: During processing, the moisture level should not exceed 0.02%, otherwise molecular degradation may occur. Suitable heat treatment may increase resistance to the formation of stress cracks. The processing notes provided merely represent a recommendation for general use. Due to the large variety of machines, geometries and volumes of parts, etc., it may be necessary to employ different settings according to the specific application.
