It is the equivalent using ISO1050 standard design,manufacturing in line with professional standards, compared with the GX series screw conveyor,head and tail bearing housings moved to the casing,the middle hanging bearing a sliding interchangeable two structures,both A dust-proof seal,the client does not have a material cleaning devices,I expected out of position layout filexibillil with low noise,strong adaptablility and facilitate the operation and maintenance,aircraft components are used in sealed nylon and Teflon resins.Resistance is small,sealed and the  characteristices of good wear resistance.Watts using the sliding bearing materials are cast copper,iron wear-resistant alloys,copper-based stone tile,and other lubrication several options. Main technical parametel are in following table.
