Requirement Review
Dimensions, tolerances, thread direction, material request, quantity, finish, and inspection documents are clarified before the route is confirmed.
Quality control for motion hardware
Quality Control for Rod Ends & Spherical Bearings
Quality requirements are defined before production starts, then matched to the manufacturing route, product, and customer inspection plan. That keeps dimensional control and release decisions connected to the part you actually order.

Quality before release
Control the Route, Then Release the Part
Each product family and application calls for its own process and inspection depth. We match the inspection plan to the drawing, sample, application, and order requirements.
Incoming Review
Material documentation and incoming checks are reviewed before the selected production process is released.
First Article
Initial parts are compared with the drawing and agreed inspection criteria so fit and critical dimensions are checked early.
Process Checks
Work instructions and in-process checks support consistency during machining, thread work, assembly, or other approved operations.
Dimensional Control
Measurement tools and hardness checks are selected by product and order. CMM, optical projection, Rockwell, thread, and other checks are used where required.
Final Release
Finished goods follow 100% inspection, sampling, or a customer-specified plan, followed by approved packing and document coordination.
Production context
Quality Follows the Production Route
Machining, assembly, affiliated production, and specialist processes may form part of one order. We explain the inspection points and records that apply to each route.
- Own Ningbo facility: precision machining, assembly, packing, and order-specific checks.
- Affiliated Jiangsu bases: rod end, ball joint, structural, and sheet-metal production capabilities.
- External process route: forging, heat treatment, welding, laser cutting, and surface finishing when required.
Where quality is managed
Quality Across the Production Network
Each site has a defined role, so you can see where machining, assembly, quality checks, and special processes take place.
Engineering & Quality Hub
620 m²38 staff
Engineering, quality management, purchasing, and international business connect customer requirements with the selected production route.
Precision Machining Facility
2,200 m²48 machines30 staff
Turning, milling, CNC machining, grinding, drilling, tapping, punching, bending, assembly, and packing are completed in-house. Forging, heat treatment, welding, and surface finishing use external processes when required.
Rod End & Ball Joint Production
6,000 m²66 machines2 lines
This affiliated production base has in-house machining, grinding, thread rolling, assembly, and inspection, with an SGS Production Trading Assessment.
Structural & Sheet-Metal Work
5,313 m²68 units4 lines
This affiliated base supports suitable structural programs with punching, laser cutting, CNC work, forming, robotic welding, shot blasting, and coating.
The Jiangsu sites are independent affiliated production bases. When a part requires forging, heat treatment, welding, or surface finishing, we coordinate the appropriate qualified process and explain the route for your program.
Documents and verification
Quality Evidence Available by Order
The inspection package is tailored to the product, production route, and customer requirements. We can include the relevant documents in the quotation and project review.
Material Records
Material certificates and incoming-document checks can be included when required by the order.
Dimensional Reports
First-article and dimensional inspection reports can be prepared against the approved drawing and inspection plan.
Process Evidence
Thread, hardness, assembly, or customer-specified checks are considered according to the component and route.
Third-Party Review
Client visits and third-party inspections can be arranged for the relevant production site and order.

Buyer questions
Quality Control FAQ
Clear answers before you send a drawing, sample, or inspection plan.
What quality system does SYZ use?
SYZ Machine operates under an ISO 9001:2015 quality management system. Certificate No. 11425Q49262R0S is valid through 9 September 2028, and the certified production address is in Fenghua District, Ningbo, Zhejiang.
How is the inspection plan selected?
The inspection plan is matched to the product, drawing, production route, and customer requirements. Finished goods may follow 100% inspection, sampling, or a customer-specified plan.
Can you provide material and dimensional documents?
Material certificates, first-article or dimensional inspection reports, inspection plans, and other OEM documents can be included when required by the product and order.
Are all production batches traceable to the raw-material heat number?
Traceability depends on the production route. The Wuxi affiliated rod end and ball joint base maintains documented raw-material batch traceability. For Ningbo production, we provide the records available for the order and explain the applicable scope before production.
Do all SYZ products have the same RoHS scope?
The current TÜV Thüringen RoHS 2.0 documentation specifically covers the XM, JMX, and CM rod end bearing series. Testing for other product lines is available on request.
Can a customer arrange a third-party inspection?
Yes, client visits and third-party inspections can be arranged for the relevant production site and order. We coordinate the site and inspection scope with you in advance.
