Key Features & Advantages
⚙️
Precision Hobbed Teeth
CNC gear-hobbing delivers DIN Grade 6 accuracy, guaranteeing smooth meshing at all speeds and reducing noise in sensitive equipment.
感应淬火齿形
High-frequency induction hardening achieves HRC 50–60 surface hardness with deformation ≤0.05 mm, tripling service life compared to untreated alternatives.
Full Simplex & Duplex Range
Stocked in Z=8 to Z=125 simplex, with duplex (03B-2) variants available for higher-load configurations in the same compact envelope.
✅
Multi-Standard Compliance
Conforms to ISO 606, DIN 8187, and BS/JIS equivalent standards, ensuring seamless retrofits on European-designed machinery operating in Australia.
Compatibility & Selection Guide
兼容 DIN 8187 03B-1 roller chain (pitch 5.000 mm, inner width 3.18 mm, roller Φ 3.2 mm). Bore range: standard hub or custom finished bore upon request. Suitable shaft diameters: typically 6–25 mm depending on tooth count and hub style.
Selection by load: Use simplex (03B-1) for light duty; upgrade to duplex (03B-2) when torque exceeds single-strand capacity. Selection by speed: For high-speed drives (>2000 rpm) prefer Z≥17 to reduce chordal action. Contact our engineers for free selection support.
Material & Manufacturing
Material: 1045 carbon steel (C45). Heat treatment: Tooth-profile induction hardening — case depth 1.5–3 mm, HRC 50–60 surface. Core remains tough (HRC 28–35) to absorb shock loads. Surface finish: Black oxidising (standard), zinc plating or geomet coating (corrosion-resistant option). Dimensional deformation: ≤0.05 mm post-heat-treatment, maintained by CNC straightening fixture.

常问问题
► What chain does the ISO 03B-1 sprocket use?
The ISO 03B-1 sprocket mates with DIN 8187 03B-1 roller chain: pitch 5.000 mm, inner width 3.18 mm, roller diameter 3.2 mm. It is also interchangeable with chains marked to ISO/BS 606 03B.
► Are simplex and duplex 03B sprockets interchangeable?
No. Simplex (03B-1) and duplex (03B-2) sprockets differ in hub width and chain-path geometry. You must match the sprocket type to the chain strand count.
► What bore sizes are available?
We supply ISO 03B-1 in plain bore (finished to drawing) or stock bore. Custom bores with keyway are available with 5–7 day lead time.
► Can these be supplied in stainless steel?
Yes. We offer SS304 stainless versions for corrosive or food-contact environments. Lead time is typically 2–3 weeks for stainless special orders.
► What is the minimum order quantity?
MOQ is 10 pieces for standard sizes. For custom bore or non-standard tooth counts, MOQ is typically 50 pieces. Contact us for exact pricing.
Installation Guide
- Inspect shaft and bore for burrs; clean and de-grease contact surfaces.
- Slide sprocket onto shaft and align with the mating sprocket using a straightedge across the tooth faces — misalignment should be less than 1 mm per 300 mm of centre distance.
- Secure with keyway and set screw or taper bush per the torque specification (refer to hub marking).
- Install 03B-1 roller chain and adjust tension: sag on the slack strand should be approximately 2% of the centre distance.
- Verify chain engages smoothly at slow speed before full-load operation.
Maintenance
Lubrication: Apply chain lubricant every 200 operating hours or monthly (whichever is sooner) for standard environments. Food-grade NSF H1 lubricant recommended for food applications. Wear inspection: Replace sprocket when tooth-flank wear exceeds 0.3 mm or when the chain skips under normal load. Chain elongation: Replace chain when elongation exceeds 2% of nominal pitch length — worn chain accelerates sprocket wear dramatically.
