Raydafon Technology Group Co., Limited is an ISO 9001:2015 and TS16949 certified manufacturer and supplier of agricultural gearboxes, industrial reducers, PTO shafts, roller chains, sprockets, pulleys, couplings, gear racks, hydraulic cylinders and pneumatic components. Founded in 2006 and based in Ningbo, China, we support agricultural machinery builders, industrial distributors and MRO buyers across 100+ countries with factory-direct pricing, in-house engineering and a 24-hour quotation response.
What sets us apart: Send us a competitor part number or a worn sample — our engineers reverse-engineer it, match the material and heat treatment, and return a cross-reference drawing before you commit to tooling. No other Ningbo supplier publishes this workflow.
We organize our engineering capability around the equipment you build. Tell us the machine, load and working environment — we will recommend the material, heat treatment and mounting configuration that fits.
Every batch of chains, sprockets, gearboxes and hydraulic cylinders leaves our factory with documented dimensional inspection, hardness test reports and material traceability. Certificates are available for download or attached to your shipment documents on request.
Answers from our engineering team based on real OEM projects across agricultural, industrial and construction machinery. Send your drawing for a specific recommendation within 24 hours.
All Raydafon products are manufactured under ISO 9001:2015 and TS16949 quality management. Roller chains meet ANSI/DIN/ISO specifications, gearboxes and PTO shafts comply with CE requirements, agricultural components are tested for durability in harsh environments, and hydraulic cylinders are pressure-tested to 1.5× rated working pressure before shipment. Certificates and batch inspection reports can be attached to your shipment documents on request.
Yes. We provide full OEM/ODM services for gearboxes, PTO shafts, sprockets, chains, pulleys and hydraulic cylinders — custom sizes, materials, coatings, bore configurations and packaging. Send 2D/3D drawings, a working sample, or high-resolution photos with key dimensions. Minimum order quantity for custom items starts from 50 pieces. Our engineers can work from your drawings or reverse-engineer an existing sample with material matching and heat-treatment verification.
For standard stock items such as roller chains, sprockets and pulleys, lead time is 7–14 days. For custom OEM orders including agricultural gearboxes and hydraulic cylinders, typical lead time is 20–30 days depending on complexity and quantity. Urgent orders can be expedited — contact our sales team for options.
Yes. We offer free samples for standard products (buyer pays shipping). For custom products such as non-standard gearboxes or hydraulic cylinders, sample costs may apply but will be deducted from your first bulk order. Sample lead time is 20–25 days after drawing approval. Contact our sales team to request a sample.
We follow a multi-stage quality control process: incoming raw material inspection (spectrometer analysis), in-process dimensional checks (CMM), 100% final testing (load tests for chains, dynamic balance for pulleys, fatigue tests for PTO shafts, pressure tests for hydraulic cylinders), and random audits by our ISO 9001 certified team. Material certificates and inspection reports are issued for every batch.
Yes. Send a physical sample, high-resolution photos with key dimensions, or a competitor part number. We measure, model in CAD, match the material and heat treatment, and return a cross-reference drawing for your confirmation before tooling starts. This service is free for standard processes and covers material verification, hardness testing and dimensional validation.

An excavator telescopic rotary hydraulic cylinder is a specialized hydraulic component that enables both linear extension/retraction and rotational movement. It works by using pressurized hydraulic fluid to actuate multiple nested stages for extension, while a separate hydraulic motor or rotary actuator integrated within the cylinder provides controlled rotation. This dual-function design allows for complex, precise positioning of attachments like grapples or augers in tight spaces, enhancing the machine's versatility and efficiency.
