Stainless steel roller has good radial beat quantity. It is less than 0.5mm(usually) and has large capacity. Smaller resistance and excellent to prevent rain and dust into the tolerance, can obtain more small rotary resistance. The requirement on permeability of ordinary belt conveyor, the groove of roller side roller slot corner is generally 35°, and introduces the hexagon conveyor roller group side roller Angle is 60°and 90°,so if the seal is bad \,rain is immersed in a short time, can appear roller damage. So both conveyor roller to stricter requirements of seal. Shaft : Accurate shaft will be made of special machining mechanism. Pipe : Rollers are made of accurate pipe with state-of roundness and straightness to ensure well-balanced ratation. Ball-Bearing : Optimum fit given between ball bearing ,shaft and housing, based upon years of experience. Ball-Bearing provided with C3 group of clearance,ZZ shield deep-groove to ensure a nice fit and off-set any expected temperature rise during operation by means of internal clearance. Housing : Housing made of deep-drawn material,cast on accurate mould ,and wil be automatically welded to pipe simultaneity at both sides.Rigid and mono-block structure so produced ensures to make it free from any looseness between pipe and housing or breakage,resultantly provide with satisfactory durability for high-speed conveyor susceptible to expected big impact during operation. Labyrinth Seal : The particular labyrinth seal structure excogitated in our company is of non-contact type,and so durable and has less rotation-resistance and long life-span as to be of optimum structure, particularly for a long-distance and large capacity conveyor for bulk material.It is approved from the testing of national authoritative organization and NC Company that Seal employ is of dustproof and waterproof type,whose performance proved to be satisfactory and has by a long way exceeded the GB and JIS standard after our repeated research and development.
