Feature:

 

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 rotation.

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 will be automatically welded to pipe simultanenity 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 conveyer susceptible to expected big impact during opetation. 

Labyrinth Seal: The particular labyrinth seal structure excogitated in our company is of non-contract 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 conveyer for bulk material .It is approved from the testing of national authoritative organizative organization and NC Company that Seal employed is of dustproof and waterproof type ,whose performance proved to be satisfactory and has by a long way exceed the GB and JIS standard after our repeated research and development.

 production facilities of automatic idlers,automatic welding devices for pulleys,and modern assembling and testing equipments.Moreover,we manufacture and assemble products strictly according to the technology for idler and pulley production provided by Nippon Conveyer Company to ensure that we contribute to our customers with the products of high precision,long life-span(more than ****0 hours),low rotation resistance(f≤0.**0),and well energy saving effects,which are applicable to all kinds of long-distance belt conveyers.The life-span of pulley,s main body is ensured to be more than six years of continuous operation.
