High-quality rollers are suitable for conveyors with long distances, harsh working conditions and high requirements. They can be used indoors and outdoors throughout the year and have a wide range of appli- cations. The design life is more than 30,000 hours and the warranty is one years. The bearing design life is10 years.
(1)The shaft is the pull shaft of light ,the roughness is 0.8 microns, the diameter is bigger 0.01mm than bearing inner diameter,so it ensure the axial displacement and axial load.
(2)Tube is dedicated welded roller pipe, the thickness of pipe is from 2.75mm to 5mm, ovality is between
0.4 mm to 0.6 mm, run-out for produced roller is between 0.5 to 0.7mm.There is little difference according to the roller pipe length and roller pipe diameter.
(3)High-quality bearings specially used for idlers can effectively prevent dust. The grease is Changc- heng brand grease. The operating temperature range is from minus 40 degrees to minus 180 degrees. lt can be used in extremely cold and very hot areas. lt can prevent the grease from seeping out during the opera- tion of the bearing and ensure the long-term lubrication of the bearing.The clearance is C3 and the noise is39 to 42 decibels.
(4)Seal is the national standard DT Il 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 tube undergoes a special process to remove rust to increase the adhesion of the paint film. The roller is powder sprayed with baking paint. The baking paint is bright in color, acid and alkali resistant, hard and abrasion resistant.Different colors are available.
(7) The packaging including bare packaging, pallet packaging, and wooden box packaging.
