Reviewed 28 October 2026. Source dating: Official detail published 24 January 2018; body, original photo and parameter sheet reviewed 28 October 2026. No new-release or current-stock claim. Catalogue family and model examples retained; illustration is representative, not an exact model.
What the official reference establishes
The official 12B-2 detail is dated 24 January 2018 and links a BS/DIN standard roller-chain duplex sheet. The 12B-2 row lists 19.05mm pitch, 11.68mm width between inner plates, 12.07mm roller diameter and 19.46mm transverse pitch. The two-strand arrangement and transverse geometry are part of the identity, not optional information hidden by the base code.
Define the work before choosing a configuration
Ask for the existing chain marking, strand count, roller and inner-width measurements from the approved drawing, sprocket specification, total length and complete operating duty. The 19.05mm pitch also appears in unrelated chain references, including the BL644 leaf-chain row, but equal pitch does not establish the same construction, load path or interchangeability. A current chain-and-drive review must consider the whole specified arrangement.
Keep the supply package explicit
Keep duplex roller-chain supply distinct from forklift mast-chain replacement. The company’s broad forklift application statement does not prove this product fits a particular truck or lifting mechanism. Table tensile figures do not establish working load, drive power, service life or machine safety. Confirm material, finish, connecting-link scope, exact documents, current availability and warranty with the quoting entity. No drive setting, installation, lubrication or repair instructions are provided.
Questions for the proposed product
Which complete chain specification is being quoted?
State the full series and suffix, construction, pitch, plate or strand arrangement, pin/roller/bore geometry, length, end connections and any attachments. Request the current approved drawing tied to the offer.
What proves the application match?
Provide the installed equipment identity and its chain specification to the responsible technical party. Require written application review. Similar pitch or appearance and catalogue tensile strength do not establish interchangeability or allowable lift load.
What is included and documented?
Confirm quantity, current availability, material/finish, connecting and attachment scope, traceability, required technical documents, delivery and warranty. Website categories do not independently prove certification, stock, authorization or vehicle fitment.
From product research to a comparable request
Prepare a written component requirement preserving the installed equipment identity and full chain specification. Compare the correct chain series, construction, pitch, geometry, length, end connections, attachment pattern, material and documentation. Keep unresolved differences visible for technical review. Existing supplier and purchasing tools remain below; following a link does not itself send an enquiry.
Sources and evidence boundary
The official contact body identifies Jinhua Hongshuo Chain Co., Ltd. at No.1389 Xianyuan Road, Wucheng District, Jinhua, Zhejiang. The company-controlled product bodies, individual original photos and linked parameter sheets were read directly. The product details retain their 24 January 2018 publication dates; a current reachable page is not proof of a new release, current stock or unchanged specifications. Supplier standard-series headings are not independent certification. Generic forklift application wording does not approve every chain for a truck. Confirm the current complete specification, application, contracting entity and documentation. Images explain chain form and are not dimensional, strength, factory or test evidence. No installation, replacement, adjustment, joining or lifting procedures are provided.
