Compatibility & Selection Guide<\/h2>\n

Compatible with DIN 8187 03B-1 roller chain<\/strong> (pitch 5.000 mm, inner width 3.18 mm, roller \u03a6 3.2 mm). Bore range: standard hub or custom finished bore upon request. Suitable shaft diameters: typically 6\u201325 mm depending on tooth count and hub style.<\/p>\n

Selection by load:<\/strong> Use simplex (03B-1) for light duty; upgrade to duplex (03B-2) when torque exceeds single-strand capacity. Selection by speed:<\/strong> For high-speed drives (>2000 rpm) prefer Z\u226517 to reduce chordal action. Contact our engineers<\/a> for free selection support.<\/p>\n

Material & Manufacturing<\/h2>\n

Material:<\/strong> 1045 carbon steel (C45). Heat treatment:<\/strong> Tooth-profile induction hardening \u2014 case depth 1.5\u20133 mm, HRC 50\u201360 surface. Core remains tough (HRC 28\u201335) to absorb shock loads. Surface finish:<\/strong> Black oxidising (standard), zinc plating or geomet coating (corrosion-resistant option). Dimensional deformation:<\/strong> \u22640.05 mm post-heat-treatment, maintained by CNC straightening fixture.<\/p>\n

\n\n►  What chain does the ISO 03B-1 sprocket use?<\/summary>\n
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.<\/div>\n<\/details>\n
\n\n►  Are simplex and duplex 03B sprockets interchangeable?<\/summary>\n
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.<\/div>\n<\/details>\n
\n\n►  What bore sizes are available?<\/summary>\n
We supply ISO 03B-1 in plain bore (finished to drawing) or stock bore. Custom bores with keyway are available with 5\u20137 day lead time.<\/div>\n<\/details>\n
\n\n►  Can these be supplied in stainless steel?<\/summary>\n
Yes. We offer SS304 stainless versions for corrosive or food-contact environments. Lead time is typically 2\u20133 weeks for stainless special orders.<\/div>\n<\/details>\n
\n\n►  What is the minimum order quantity?<\/summary>\n
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.<\/div>\n<\/details>\n

Installation Guide<\/h2>\n
    \n
  1. Inspect shaft and bore for burrs; clean and de-grease contact surfaces.<\/li>\n
  2. Slide sprocket onto shaft and align with the mating sprocket using a straightedge across the tooth faces \u2014 misalignment should be less than 1 mm per 300 mm of centre distance.<\/li>\n
  3. Secure with keyway and set screw or taper bush per the torque specification (refer to hub marking).<\/li>\n
  4. Install 03B-1 roller chain and adjust tension: sag on the slack strand should be approximately 2% of the centre distance.<\/li>\n
  5. Verify chain engages smoothly at slow speed before full-load operation.<\/li>\n<\/ol>\n

    Maintenance<\/h2>\n

    Lubrication:<\/strong> 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:<\/strong> Replace sprocket when tooth-flank wear exceeds 0.3 mm or when the chain skips under normal load. Chain elongation:<\/strong> Replace chain when elongation exceeds 2% of nominal pitch length \u2014 worn chain accelerates sprocket wear dramatically.<\/p>\n
