Zhejiang Dongsheng Chain Co., Ltd.
浙江东盛链条有限公司
Zhejiang Dongsheng Chain makes transmission, conveyor and agricultural chain in Yongkang under the Dongsheng and Huanli brands. Its CA agricultural chain comes with a size table covering seven designations, from CAE44151 at 28.575 mm pitch to CA620 at 42.01 mm. Buyers replacing a harvester or conveyor chain should pick one designation, send the sprocket and attachment drawings, and agree the working duty with Dongsheng.
Dongsheng chain families and what to specify
Dongsheng's introduction covers several chain types and lists users in machinery, food, textiles, transport and mining. Decide first whether you need a drive chain, a conveyor chain or a chain with attachments, then send the matching details below. For a second offer, the SFR S62 agricultural roller chain and the SFR ZGS38 combine chain with attachments are comparable chains from another maker.
[1][2]| Chain family | What to send with the enquiry |
|---|---|
| Precision roller and double-pitch chains | Full designation, geometry and the drive or conveyor duty. |
| Bent-plate and heavy-duty families | Construction, sprocket engagement, load and cycling, and fit in the machine. |
| Conveyor and agricultural chain | Attachment pattern, working elements, timing along the assembly and the dirt it runs in. |
| Stainless chain | Grade, finish and intended use. The CA agricultural chain is listed as steel, so ask separately if you need stainless. |
Models and specifications
Quote the exact model, configuration and operating conditions together, and ask the factory to confirm current availability.
Dongsheng CA-type Steel Agricultural Chain
Catalogue reference: CA-type agricultural chain
Dongsheng's CA-type steel agricultural chain is sold as a family, and the size table on its product images lists each designation separately. CA550, CA550V and CA557 share a 41.40 mm pitch; CA620 runs at 42.01 mm, the CA2060H and CA2063H at 38.10 mm and CAE44151 at 28.575 mm. Use the table to identify a replacement chain, then agree sprocket fit, joining link, attachments and the working load with Dongsheng. The tensile columns give breaking strength, so ask for an allowable duty as well.

CA agricultural chain sizes
Dongsheng's CA chain page carries two dimension drawings and a size table as images. The drawings label pitch P, inner width b1, roller diameter d1, pin diameter d2, pin lengths L and Lc, plate height h2 and plate thickness T. Seven of the listed designations appear below.
Several rows share a 41.40 mm pitch but differ in pin, width and link length, so choose one full designation and keep its whole row together. The tensile columns give breaking strength; ask Dongsheng for the allowable working load for your machine.

Turning a CA size into an order
The size table covers bare chain geometry and breaking strength. Attachments, permitted operating load, fatigue duty and the material and inspection package for an order are settled with Dongsheng directly.
Send your existing sprocket and chain drawing, or a labelled sample, and agree the designation, attachments, joining link and operating duty in writing before the first shipment. For what a complete roller or attachment chain specification should contain, see our notes on agricultural roller chains and attachment chains.
[2][5]Company background
Dongsheng traces its business to Yongkang Huanli Chain Factory, founded in 2001, and has traded as Zhejiang Dongsheng since 2008. The introduction describes a factory area above 20,000 square metres, more than 200 production staff, development of non-standard chains and links with chain-transmission institutes.
If you need a custom chain, ask what drawing work Dongsheng will do for your project, which machines will make it and how each batch is inspected.
[1]Is this a fit for your project?
Based on the manufacturer's published range.
A good fit for
- Drawing-based quotes for transmission, conveyor and agricultural chain.
- Matching a CA replacement chain from a sample or an existing machine drawing.
Confirm in writing before ordering
- The exact chain size, attachment assembly and allowable working load, with current inspection and conformity records.
- Current factory size and staffing, and how much non-standard design and manufacture Dongsheng will take on for your chain.
From drawing to repeat supply
Dongsheng offers non-standard chain development. A clear drawing package lets it say which design, manufacturing and inspection work it will take on.
[1][2][3]Identify and measure
Existing chain, sprockets, wear on the sample and the dimensions that matter.
Define the assembly
Attachments, link count, joining parts, timing, guides and clearance.
Set duty and finish
Load and cycling, speed, dirt exposure, and the build, material and maintenance Dongsheng rates for that duty.
Agree records and repeat orders
Drawing approval, sample acceptance, traceability, inspection records and replacement parts.

Standards cited and the Yongkang listing
The introduction cites GB/T 1243-1997 and ISO 9001-2000. For an order, ask for the current certificate with its scope and for chain test records that match the size you buy. An ISO 9001 certificate covers how the factory is managed; chain load ratings come from product data.
Yongkang's government notice on the 2023 industrial-enterprise economic and resource evaluation, issued on 10 October 2024, lists Dongsheng in the below-scale attachment at entry 167, category B. This is an economic ranking of local firms and carries no product grade.
[1][4]Questions buyers should settle
What does the category B listing mean?
It comes from Yongkang's 2023 economic and resource evaluation of local firms. It ranks the company economically and does not grade its chain.
[4]Is Dongsheng certified to GB/T 1243 and ISO 9001?
Which CA sizes does Dongsheng list?
The size table includes CA550, CA550V, CA557, CA620, CA2060H, CA2063H and CAE44151, with pitches from 28.575 mm to 42.01 mm.
