Premium roller, It is used for long distance, large capacity, high speed and operating at poor environment of high standard belt conveyor. It has a wide application. The design life is more than50000 hours.The warranty period is one year.The bearing design life is 10 years.
(1)The shaft is the pull shaft of light , roughness is 0.8 micron,shaft diameter is more 0.01mm than the bearing inner diameter, so that it ensure the axial displacement and axial load.
(2)We adopt the dedicated seamless roller pipe, the pipe thickness is 3.25mm--5.0mm,oval- ity is between 0.25mm--0.4mm, so the roller diameter run-out is under 0.5mm.
(3)The bearing is import bearing, Bearing we used is sealed tight double labyrinth seal,Bear- ing has a V-shaped groove, and Grease is the imported grease. lt can be operated smoothly at the temperature from minus40degrees to 180 degrees above zero. The roller can be used in very hot and very cold regions, the bearing is dust-proof and water-proof. And it can also prevent bearing grease oozing during operation and ensure long-term lubrication of bearings,Clearance is C3 and noise is 34-38 db.
(4)Seal is the national standard DT II seven pieces seals, Including 4 pieces POM and 3 pieces steel seal, and middle are injected 2/3 of the Great Wall of grease in order to ensure the bearing move smoothly and also ensure the roller to be dust-proof and waterproof.
(5)The thickness of snap is 2mm, which material is 65Mn spring steel material.
(6)The roller pipe was polished by the special Polishing machine, so it can increase the adhe- sion of the paint. There is one baking paint and the color is bright, and it is acid-proof, alkali-re- sisting, hard and durable.There are several kinds of paint color for your choice.
(7) After cap packaging, packing includs bare packaging, pallet packaging, and wooden box packaging.
