Product Advantages
- Strict coaxiality control for long shaft, avoiding jamming during reciprocating movement
- Precise knurl, thread and hole position machining for stable assembly performance
- Solid stainless steel raw material with excellent mechanical strength and corrosion resistance
- Support for custom bent angles, shaft diameters, total lengths, and thread specifications according to drawings
- Complete deburring treatment with no sharp burrs on any edge of finished parts
Kindly send us your 2D/3D drawings or technical requirements including total length, diameter, thread size, bent angle and quantity. Our engineering team will offer competitive quotation and lead-time promptly.
Quality Assurance
Each batch of long shaft and bent link rod undergoes full dimension inspection before delivery. We check shaft straightness, thread dimension, hole position, and bent angle. Production inspection records are available for bulk orders, and third-party inspection is supported.

Packing & Shipping
Each part packed in dust‑proof plastic bag, fixed with EPE foam for anti‑collision, packed in export carton. Custom shipping marks available.
We support multiple shipment options: DHL, FedEx, UPS for express small‑batch orders; sea freight and air freight for mass production. Shipping method can be selected according to your order volume and delivery schedule. All packages come with packing list for customs clearance.
Lead‑time depends on drawing confirmation, material availability and order quantity. We will advise estimated delivery date before order confirmation.

Frequently Asked Questions
Q1: Can you make non-standard long shaft and bent link rod per my drawing?
A1: Yes, we fully support OEM custom production based on your 2D or 3D files. All dimensions and structures can be customized.
Q2: What problem will happen if long shaft has poor coaxiality?
A2: Poor coaxiality will cause vibration, noise and abnormal wear during high-speed reciprocating operation. We focus on straightness control for long shaft parts to prevent these issues.
Q3: What is your production lead-time?
A3: Sample orders require 7-10 working days. Mass production lead time depends on order quantity and processing complexity.
