Product DescriptionProduct DescriptionTotem Heavy-Duty Precision Vertical Stand Shafts for Rolling MillsThis high-performance vertical support shaft for rolling mills is forged from premium alloy steel, precision-machined and heat-treated to deliver exceptional rigidity, wear resistance, and fatigue strength. Designed for high-speed, heavy-load rolling mill stands, it ensures precise rolling operations and equipment stability. update:2025-07-31Detail PhotoSpecificationApplications1.Vertical support systems for hot/cold rolling mill stands2.Main drive shafts for non-ferrous metal rolling mills3.Load-bearing structures in heavy-duty rolling equipmentCustomization OptionsCoatings: Nitriding,CeramicConnections: Keyway,Flange,SplineLength: 1m-6mrolling mill component manufacturingISO 9001 & CE certifiedDynamic load test reports availableMachinery ProcessingKey ConfigurationsMaterial Preparation: Alloy steel bars Forging: Multi-directional forging for refined grain structureRough Machining: Turning with precision machining allowanceHeat Treatment: Quenching & tempering to HRC 28-32Precision Machining: CNC turning (IT6 tolerance)Surface Treatment: High-frequency hardening/Hard chrome plating (optional)Inspection: Ultrasonic testing + CMM verificationEngineered for extreme operational demands, our vertical stand shafts are the backbone of modern rolling mill systems. Manufactured from vacuum-degassed 34CrNiMo6+QT alloy steel, these shafts undergo multi-stage thermo-mechanical processing to achieve unmatched fatigue resistance (≥10 cycles at 90% of yield strength). The induction-hardened surface layer (3-5mm depth, HRC 58-62) combined with a tough core (HRC 30-34) ensures optimal wear performance under continuous heavy loads up to 250 metric tons.Precision-ground to ISO h6 tolerance with ≤0.005mm/m straightness deviation, each shaft features proprietary micro-texturing on bearing surfaces to enhance lubricant retention. Custom flange configurations (ISO 9409-1 standard) and anti-rotation splines (DIN 5480) are available for seamless integration with mill stands.Technical Specifications(Custom configurations available upon request.)ParameterValueMaterial42CrMoA HardnessHRC 28-32Diameter Tol.±0.01mmStraightness≤0.05mm/mRa≤0.8μmMax Load150kN (/static)HOT SALE PRODUCTSCompany ProfileSHANGHAI TOTEM MACHINERY CO., LTD.Shanghai Totem Machinery Co., Ltd.
