TOPONE DIN 764 Chain is a welded medium link round steel chain designed for compatible chain conveyors, bucket elevators, scraper conveying systems, and industrial material-handling equipment.
Available in nominal chain link diameters from 4mm to 26mm, our DIN 764 chain range includes different material and surface treatment options, including carbon steel, electro-galvanized, hot-dip galvanized, and blackened finishes.
As a China-based industrial chain manufacturer and supplier, TOPONE supports standard chain sizes, custom lengths, dimensional specifications, and bulk orders for conveyor manufacturers, equipment maintenance companies, and industrial distributors.
DIN 764 chains are not intended for overhead lifting or use as lifting chain slings.
TOPONE CHAIN manufactures and supplies DIN 764 medium link chains for industrial conveying and material-handling applications.
Our welded round link chains are available in different diameters, materials, and finishes. Their dimensions support use with compatible conveyor wheels and attachments, provided the complete system meets the approved equipment specification.
With nine automated chain production lines and experience in industrial chain manufacturing, TOPONE supports OEM orders, replacement conveyor chains, and international bulk supply.
For buyers requiring matching conveyor components, TOPONE also offers Plain Segmented Chain Wheels for selected DIN 764 chain applications.

TOPONE is a China-based industrial chain manufacturer and supplier with experience in producing round steel link chains for multiple industrial applications.
Its broader manufacturing operations include:
· 9 automated chain production lines
· More than 5,000 m² of manufacturing and warehouse space
· More than 15,000 m² of total building area
· Published annual capacity exceeding 500,000 high-strength load chains across the company
These figures describe TOPONE's overall chain manufacturing capability rather than a separately verified annual DIN 764 production capacity.
For applicable round link chain products, manufacturing activities may include steel material preparation, link forming, welding, heat treatment where required, calibration, dimensional inspection, and final quality control.
The exact production route must follow the confirmed chain grade and approved technical specification.
TOPONE supports OEM chain orders, custom lengths, selected material options, and bulk industrial chain procurement.

The DIN 764 standard family includes the following relevant parts:
DIN 764-1:2010-10 — Grade 3
This standard addresses tested, fine-tolerance round steel link chains for chain conveyors, including applicable dimensions and mechanical requirements.
DIN 764-2:2010-10 — Grade 5
This standard addresses tested, fine-tolerance round steel link chains for chain conveyors with Grade 5 requirements.
Both parts specify nominal chain geometry with a pitch relationship of approximately 3.5 times the chain diameter.
Product conformity must be evaluated against the applicable standard part, grade, dimensions, and test requirements.
Custom chain dimensions or nonstandard materials may be supplied according to customer specifications, but such products should not automatically be described as fully compliant with DIN 764-1 or DIN 764-2.
Quality verification should follow the chain grade, product specification, and agreed inspection requirements.
Depending on the approved product, relevant verification may include:
· Steel material identification
· Chain link diameter measurement
· Chain pitch and link width inspection
· Cumulative multi-link length verification
· Weld quality inspection
· Manufacturing proof testing
· Minimum breaking-force testing
· Surface treatment inspection
· Final product identification and documentation
The actual testing method, test force, sampling requirements, and acceptance criteria must correspond to the ordered product.
Buyers may request applicable dimensional inspection reports, proof-test records, breaking-force records, and material documentation according to their project requirements.
DIN 764 chains are primarily intended for suitable industrial chain conveyors and related material-handling systems.
Typical applications include chain conveyors, bucket elevators, scraper conveyor systems, and industrial replacement chain arrangements.
The complete system must be evaluated for chain diameter, pitch, attachment geometry, operating load, environmental conditions, and mating wheel compatibility.
Safety Warning: DIN 764 chains covered by DIN 764-1 and DIN 764-2 must not be used as overhead lifting chains, lifting slings, or crane load-carrying attachments.
Products intended for overhead lifting require separate approved lifting-chain specifications.
Inspect conveyor chains according to the equipment manufacturer's instructions and site maintenance requirements.
Check for:
· Chain elongation and pitch changes
· Excessive interlink wear
· Damaged or deformed links
· Cracks and weld defects
· Abnormal corrosion
· Worn chain wheel surfaces
· Attachment damage
· Incorrect chain wheel engagement
Replace damaged or nonconforming chain components according to the approved equipment maintenance procedure.
Do not mix incompatible replacement chains or modify chain dimensions without engineering approval.
TOPONE supplies DIN standard chain products for international distributors, conveyor equipment manufacturers, industrial maintenance contractors, and bulk material-handling projects.
Our supply services include standard chain specifications, OEM dimensional review, selected materials and surface finishes, custom lengths, inspection arrangements, and export packaging.
