Product Description Product Description Product DescriptionConveyor rollers are used to support and shape the conveyor belt. Conveyor carrier rollers can be fitted to the load side of the belt in: trough, tracking and transition frames, or fitted to the return side of the belt.DiameterΦ89, Φ102, Φφ108, Φ114, Φ127, Φ133, Φ139, Φ152, Φ159, Φ165, Φ194Length145mm-2800mmShaftA3 and 45# steelShellQ235(GB), Q345(GB), welded with DIN2394 standedBearing6204/6205/6305/6206/6306/6307/6308/6309/6310Working LifeMore than 30000hoursAdvantagesLow resistance, waterproof, dustproof etc. Conveyor Roller IDLERS features:1. We are in desiging conveyor rollers combines the requirements of high quality and labyrinth seal.2.Roller Shell : consist of a selection steel tube,machined at either to strict tolerance.3.Bearing house : Formed from strip deep pressed and calibrated to ISO M7.this tolerance allowing a perfect match between the bearing and the relevant parts on the sealing.4. The roller shell and the two bearing housings are welded together in an way that forms a monolithic structure of exceptional strength. This method guarantees the maximum precision and the minimum out of balance forces in the rollers.5. Seal :Triple Labyrinth Seal design is grease filled and offers an additional level of protection from contaminants impacting the bearing CEMA C, D and E Idlers have sealed for life ball bearings.6.Wide range of working temperatures from 0o C to 100o C.7.Final Testing: Dimension,surface, Radial circular runout,Rotational resistance,Axial load,Water immersion seal,Axial displacement,Drop test.Conveyor Rollers Production Process: Conveyor Roller Advantage:Triple Labyrinth SealSealed for life ball bearingsExtremely low rolling resistanceCEMA C & D standard product lineIdler end weldingSolid steel shaftgauge steel shell/coverImpact Roller Idlers:Impact rollers are used as carrying rollers instead of normal steel rollers at a loading point. On steel roller there are rubber rings assembled, side by side, to absorb the weight and impact of material falling onto the belt. At the same time impact rollers reduce the shock and vibration through the steel structure.Specification of Impact Conveyor Roller Idlers:Diameter(mm)Shaft DiameterBearing Part No.Min Bearing DynamicLoading Pating(N)127mm25mm620514000N133mm25mm620514000N152mm25mm620514000N159mm25mm620514000N127mm25mm630522500N133mm25mm630522500152mm25mm630522500N159mm25mm630522500N152mm30mm630628100N178mm30mm630628100N178mm35mm630733200N203mm35mm630733200N178mm40mm630841000N203mm40mm630841000N203mm45mm630952700N203mm50mm631061800N250mm60mm631281900N Product ParametersSteel Spiral Return Roller IdlerThe steel spiral return idler are used as support for the return side of belt. Used where sticky, corrosive, or abrasive materials are present. Not only cleans itself, but keeps the belt cleans and double spiral configuration minimizes belt training problems such as misalignment.Specification of steel spiral roller idler:DiameterLengthBearing ModelShaft Diameter89mm950mm620420mm108mm950mm620525mm108mm1150mm620525mm108mm1400mm620525mm108mm1600mm620525mm133mm950mm630525mm133mm1150mm630525mm133mm1400mm630525mm133mm1600mm630525mm159mm1150mm630630mm159mm1400mm630630mm159mm1600mm630630mmRubber Disc Return Roller IdlerDisc Return Rollers are used where the material has the potential to collect on the surface of the rollers which could ultimately lead to premature failure. The Ring minimises material build up on the roller shell. To maximise longevity, routine cleaning should still be observed. Rings come in rubber as standard.Friction self -aligning conveyor rollers specifications:Diameter(mm)89.7-193.7mmLength(mm)500-1400(Total Length:674-1630)Shell Thickness(mm)3.2-4.5StandardDIN,CEMA,JIS,AS,SANS-SABS,GOST,AFNOR etc.Nylon Rollers and Idlers:The Nylon Roller Idler is light in weight and easy to install in the air. The nylon wheel has been widely used as a tower crane accessory in various lifting equipment, and gradually replaces the normal metal pulley with its great advantages.

High-quality special welded pipes are used, and strict tolerance requirements are set. This can ensure the roundness and straightness of the idlers and reduce the wear of the conveyor belt. The shaft materials are cold-drawn round steel, which has high strength and good toughness and can bear a large load. The bearing seats are stamped from high-quality steel plates, which are sturdy and durable and provide good support for the bearings.Good Sealing Performance: The sealing structure adopts a PDC-type three-way sealing device, which has excellent dust-proof and waterproof performance. It can effectively prevent dust, water vapor, etc. from entering the interior of the bearings, extend the service life of the bearings, and reduce the maintenance cost.Low-resistance Operation: After assembly, the rollers have good strength, small radial runout, and low rotational resistance. This helps to reduce the running resistance of the conveyor belt, minimize energy consumption, and improve the efficiency of the conveying system.Long Service Life: Due to the use of high-quality materials, advanced manufacturing processes, as well as good sealing and low-resistance designs, the return idlers of this company have a long service life. It can reduce the frequency of idler replacement and improve production efficiency.Product FunctionsThe return idler is mainly used to support the unloaded section of the conveyor belt, enabling the conveyor belt to smoothly return to the driving device and form a complete cycle. It can help maintain the shape and position of the conveyor belt, prevent problems such as deviation and sagging of the conveyor belt during operation, and ensure the stable operation of the conveying system. In addition, some return idlers may also have a certain centering function, which can automatically adjust the position of the conveyor belt, further improving the reliability and stability of the conveying system.
