Steel/Rubber Impact Idler Roller for Industrial Belt Conveyors

BASIC INFORMATION OF IMPACT ROLLER Product TrademarkSKRoller Diameterφ89-φ219Roller Length250mm-2200mmRoller PipeQ235 carbon steel, high precision straight seam welded pipe with state-of roundness and straightness to ensure well-balanced rotation.ShaftQ235 carbon steel, made of cold-drawn bright round steel, which is superior in corrosion resistance and stiffness.We have strict control over tolerance of shaft dimension and surface quality.The service lifespan can be well secured and proloned.BearingC4 large clearance and double-sided sealing,which can effectively compensate for temperature rise during operationBearing BrandsHavalo, SKF, NSK, or as per your needsSeals lybarinth non-contact sealing structure, or composite sealing structure of non-contact labyrinth and contact lip, water-proof and dust-proofBearing Seatbe made of isotropic and ductile special strip steel, processed and formed through a unique seven-step stamping process, with high accuracy, light weight, certain elasticity and good stress state. TECHNICAL SPECIFICATIONS & PARAMETERS  Impact Roller ParametersStandard Diameter(mm)Length Range(mm)Bearing TypeRoller Pipe Wall Thickness(mm)89250-900mm204 ,2053.5108250-900mm204,205,305,3063.5133250-900mm205,305,306,3073.5159250-900mm305,306,307,3084.0194250-900mm306,307,308,3094.0219250-900mm308,309,3104.5PRODUCT ADVANTAGESOur company's rollers have the advantages of light weight, low resistance, small radial runout, smooth and flexible operation, low noise, long service life, and low maintenance workload.PROCESS FLOW INTRODUCTION1. ROLLER BODYa.  The roller pipe adopts automatic cutting machine, with no deformation or chips when cutting the pipe body; The perpendicularity between the fracture and the pipe is high, and the parallelism between the two ends is high;b.  The roller pipe adopts special boring machine, which can simultaneously bore both ends of the roller pipe where bearings are installed, with high coaxiality; complete the end face flatting and interior angle cutting in one go;c.  Patented Technology of A Reducing Diameter Process:  completely eliminates wear on the conveyor belt, greatly imporves the coaxiality of the idler, and effectively reduces the jumping and rotating resistance of the excircle.d.  Anti-rust Painting on the inner wall of the supporting roller: ensure good corrosion resistance.2. ROLLER SHAFTUse a slot flat double end milling machine to synchronously process the slot flat at both ends, ensuring that the slot flat of the roller shaft is symmetrical.3. BEARINGa.  domestic and foreign first-class brand roller bearings;b.  semi-automatic quantitative filling of low-temperature lithium based lubricating grease, eliminateing the need for further filling in the future, and has good cold resistance.4. SEALSThere are Lybarinth sealing structure or the composite sealing structure  for choice.5. PRODUCT ASSEMBLYAdopt automatic pressing, ensuring the overall assembly accuracy of the supporting rollers.6. WELDINGAdopt fully automatic mixed gas shielded welding, with good welding seam quality and high welding accuracy; equipped with dust removal devices, which is safe, efficient, environmentally friendly and healthy.7. COATINGAdopt a dust-free sealed and environmentally friendly automatic coating line, realizing the automatic loading &  unloading, coating, palletizing, packaging, and the harmless treatment of exhaust gas, making it the first environmentally friendly roller coating line in China to automatically load and unload parts.  QUALITY CONTROL MEATURES   1. STANDARDS All performance indicators meet or exceed the requirements of MT821 "Technical Conditions for Belt Conveyors Used in Coal Mines" and GB/T10595 "Technical Conditions for Belt Conveyors".2. TESTINGUtilize multiple roller testing equipment to inspect the radial runout, rotational resistance, axial load, waterproof, dust-proof, and drop performance of the rollers, ensuring their high performance.QUALITY CONTROL MEATURES   1.
