We build every sprocket for you with our expertise in manufacturing ultra-precision components and ISO grade 5 gears with tolerances as tight as ±0.002mm.Hansheng Automation, a supplier of precision packaging machinery components to numerous countries and regions, boasts extensive experience in custom manufacturing, exceptional product and service quality. We specialize in manufacturing high-precision components, such as custom cam indexers with an accuracy of ±15 arcsec and CNC precision components with a super-mirror finish and tolerance control of ±0.002mm. Choosing our sprockets means you're guaranteed both precision and quality.Features of sprocket wheelHigh Tooth Profile Precision: Gear manufacturing meets ISO/DIN/GB Stage 5 standards. Utilizes Kashifuji rack gear shaping machines and Seibu wire-cut EDMs for precise meshing and minimized noise.Dimensional Tolerances: Precision turning and milling maintain accuracy to ±0.005mm, ensuring correct inner/outer diameters, thickness, and concentricity.High-Quality Alloy Steel: Typically uses 45# steel, C45 steel, stainless steel, and other alloys for mechanical strength, toughness, and wear resistance.Advanced Heat Treatment: Specialized heat treatment processes such as high-frequency quenching enhance surface hardness and wear resistance.Customized Service: Strong non-standard design and manufacturing capabilities. Customization available for modules, teeth numbers, materials, and special structures per drawings and working conditions. Also offers CNC machined parts, gears (helical, turbines, etc.), castings, etc.Product Technical ParametersParameter ItemSpecification DescriptionProduct NameIndustrial Sprocket WheelExecutive StandardISO, ANSI, DIN, GB (National Standard), etc.Common Materials45# (C45/S45C), 304 stainless steel, 316 stainless steel, cast iron, nylon, etc.Sprocket TypeType A (flat plate type), Type B (single-side hub type), Type C (double-side hub type), idle sprocket, tension sprocket, etc.Number of Chain RowsSingle row (Simplex), double row (Duplex), triple row (Triplex) and multi-rowNumber of Teeth Range8 - 120 (If more than 120, please consult us)Pitch RangeCover all standard industrial chain pitchesSurface TreatmentBlack oxide, galvanized, chrome plated, spray painting, high-frequency quenchingHub FormStandard keyway, taper bushing hole, QD hole, customized apertureCustom ServiceAccept non-standard customization according to customer drawings or samplesOur sprocket wheel production processDemand Communication and Drawing Design: In-depth discussions to understand application requirements and provide professional drawing design.High-Quality Raw Material Selection: Rigorous selection of standard steel or specified materials.Precision Casting: Lost wax, sand casting, and lost foam casting processes for dense blanks.CNC Turning and Milling: Precision machining centers finish inner/outer diameters, end faces, and hub bores, achieving ±0.005mm accuracy.High-Precision Tooth Forming: High-precision equipment such as Kashifuji rack shapers for gear hobbing or shaping, ensuring tooth profile meets standards.Heat Treatment: High-frequency quenching enhances surface hardness and wear resistance while maintaining core toughness.Surface Treatment: Blackening, galvanizing, and other treatments available to enhance corrosion resistance.Strict Quality Inspection: Gear testers and coordinate measuring machines conduct final inspections of key parameters such as tooth profile, pitch, and tolerance.Application AreasPackaging machinery: sealers, labelers, canning linesAgricultural machinery: harvesters, seeders, feed processing equipmentFood processing: washing lines, baking equipment, conveyor systems (often stainless steel sprockets)Engineering and construction machinery: hoists, mixers, small excavatorsLogistics and warehousing equipment: sorting systems, racking drivesTextile and printing machineryDifference between a freewheel and a sprocketCharacteristicSprocketFreewheelEssenceA gearA mechanical device (one-way clutch)FunctionTransmits power and drives the chainAllows one-way rotation and enables coastingRelationship with ShaftRigidly fixed, rotates synchronously with the shaftOne-way coupling, can only drive the shaft in one directionInstallation PositionChainring (front) / Rear hub (rear)Only at the rear hubCommon NamesChainring plate, freewheel plate (actually inaccurate)Commonly nicknamed "rear freewheel"What happens if a sprocket breaks?Common causes: insufficient lubrication, overtightening the chain, prolonged overload. Consequences: equipment loses power and becomes inoperable; at high speeds, a broken chain can damage equipment or cause casualties.FAQHow do I choose the right sprocket for my equipment?Determine: 1) chain type (pitch and roller size); 2) required number of teeth; 3) shaft diameter and keyway size. If unsure, consult technical team.Can you produce custom sprockets for non-standard applications?Yes. Provide a drawing, sample, or technical requirements. Special materials, teeth, hub bore, or complex designs can be accommodated.What information do I need for a quote?Provide: sprocket type, material, number of teeth, pitch, shaft bore diameter, keyway size, heat treatment requirement, and purchase quantity.What is your production lead time?Standard sprockets: less than one week. Custom: 15-20 business days depending on complexity and quantity.How do you guarantee product quality?1) Strict raw material inspection; 2) High-precision processing equipment; 3) Precise heat treatment; 4) Complete inspection of finished products before shipment.Technical Specifications / FeaturesUltra-precision manufacturing, ISO grade 5 gearsTolerances as tight as ±0.002mmMaterials: 45# steel, C45, S45C, 304/316 stainless steel, cast iron, nylonTypes: Type A/B/C, idle, tension sprocketChain rows: Simplex, Duplex, Triplex, multi-rowTeeth: 8-120 (custom above 120)Surface treatments: black oxide, galvanized, chrome, spray paint, high-frequency quenchingCustomizable hub forms and aperturesNon-standard customization available
