Who we are
YZEFY Sprockets focuses on industrial chain sprockets for machinery manufacturers, distributors and MRO buyers. The product scope covers standard roller chain sprockets, custom parts from drawings or samples, OEM parts controlled by an equipment specification, and replacement sprocket assemblies for worn or obsolete equipment.
We work with international OEMs, transmission component distributors, MRO purchasers, maintenance engineers and industrial buyers. Projects may begin with a chain designation and a standard product family, or with a drawing, CAD file, sample, worn part or field dimensions. The working discussion centers on chain compatibility, tooth count, bore, keyway, hub, material or treatment requirements, quantity and the machine interface. When a standard catalogue part does not fit, the request moves to the relevant custom, OEM or replacement route.
What we do
Standard sprockets
Standard chain sprockets for industrial drives and conveyors, selected by product family, chain standard, strand configuration, bore and mounting style. Start with All Chain Sprockets to find the relevant product page, then confirm the chain and machine interface before requesting a quote.
Custom and OEM sprockets
For non-standard dimensions or drawing-controlled machine parts, YZEFY reviews chain compatibility, tooth geometry, bore, keyway and hub details. See Custom Chain Sprockets for drawing and sample work, OEM Sprockets for repeat production, or Custom for the wider engineering route.
Replacement sprockets
Replacement sprockets and assemblies for worn, obsolete or field-identified equipment parts. Start with the chain, tooth count and shaft interface, then add photos, a sample or reliable dimensions. See Replacement Sprocket Assemblies for the required supply scope, including a sprocket, hub, bushing or another defined assembly.
