Key features

Strictly manufactured in compliance with DIN 8187 and ISO 606 standards, ensuring 100% precision meshing with standard 12B-1, 12B-2, and 12B-3 roller chains.

Precision machined from high-grade C45 carbon steel (AISI 1045) or 40Cr alloy steel, delivering high tensile strength and superior impact resistance under heavy industrial torque.

Features high-frequency induction hardened teeth (HRC 45-52), providing exceptional surface wear resistance while maintaining a ductile core to prevent tooth breakage.

Processed with advanced CNC gear hobbing machines for high tooth profile accuracy, ensuring smooth power transmission, reduced vibration, and minimal operational noise.

Available in pilot bore, finished bore with keyway and set screws, taper-lock bushing bore, and spline bore configurations to meet all shaft mounting needs.

Offers various protective surface treatments including black oxide, zinc plating, nickel plating, and anti-rust oiling for long-term corrosion resistance in harsh environments.

Undergoes rigorous dynamic balancing testing, ensuring high rotational stability, balanced load distribution, and extended bearing and shaft lifespan at high speeds.

Supports full customization for tooth numbers (from 8T to 120T), hub dimensions, plate wheels, and non-standard specifications according to your technical drawings.

AI-Powered supplier vetting

SummaryThe supplier is a limited company in Liaocheng, Shandong, China, supplying valves and electronic sensors with 23 employees. It identifies as a professional technical supplier and provides 3D design, sample-based customization, ODM, and OEM services. Quality processes include assurance, raw-material traceability, documented inspections, complaint handling, and corrective-action procedures. The supplier has inventory capability, testing equipment, export experience, and a high stated export share, but lacks an effective contract with related manufacturing subcontractors, overseas warehouses, overseas showrooms, and an available SDK. No new products were reported in the past year, while financial credibility and customer-case evidence remain insufficient for firm assessment.

Supplier typeThe supplier is explicitly identified as a professional technical supplier, operates as a limited company, and offers valves and electronic sensors. It also provides ODM and OEM services, indicating a product manufacturer or design-manufacturing supplier rather than a general trading-only entity.

After-Sales capabilityThe supplier states that its global service network provides timely after-sales technical services and reports a clear, followed customer-complaint procedure. However, it has no overseas warehouse or showroom, which may limit local service infrastructure, although the evidence does not establish that after-sales performance is inadequate.

Production capacityThe supplier reports inventory capability, computer-controlled CNC machines, extensive spare-parts inventory, finished-product inspection procedures, and testing equipment including salt-spray and tensile-testing machines. However, there is no valid contract between the factory and related subcontractor, creating a documented manufacturing-governance deficiency despite other production resources.

Customization capabilityThe supplier explicitly offers sample-based customization, customer-specific product design and development, 3D software design, OEM customization, and ODM services. These repeated statements provide direct evidence of customization capability for specific applications.
