project overview

DESIGN & STANDARD: The idlers are suitable for bulk material handling & work in strenuous working conditions and heavy dust laden atmosphere. The end covers are designed very precisely so that it would not permit accumulation of dust & ingression of water. The design is robust & sturdy requiring maintenance limited only to cleaning the extemal surface & replacing them on conveyor run. BEARING : The idlers are itted with seize resistant & deep groove (Required for relevant items) ball bearings with C3 clearance of SKF/FAG/NTN/NBC make with sufficient amount of Hi-Lithium base grease for entire life of idlers. ROLLER SHELL : The roller shells are made from ERW pipes with close tolerance on thickness concentricity, straightness, surface finish etc. as stipulated in IS:9295 Gr. 1 (YST-210) which ensures minimum diametrical run out. In case of heavy series idlers seamless tubes are used as per customer's specification. Housing : Housing are made from deep drawn CRCA sheet as per IS:513 (As specified by customer) & are welded simultaneously at both ends of the tube by Double ended Ml welding machine. SHAFT : Shafts are made out of 40C8:45C8 as per IS: 1570/EN-8 as per BS:970 Round. SEALING : Multistage nylon labyrinth set (Nylon-6), M.S Dust Cap (CRCA, as per IS:513, Galv.) with unique sealing arrangement are provided to cnsure dust and water resistance of the rollers. IMPACT ROLLERS : Rubber disc are fitted on the roller with internal locking arrangement so that it would not run over the pipe. High abrasive resistant rubber with shore hardness 65" 5'inscale Aare used for rubber disc. TESTING EQUIPMENT: We have all type of Testing Equipments of Idler Rollers Dust Ingress Testing, Friction Factor Testing, Radial Run Out Test Fixture, Water Ingress Testing OVAS
