Fitur Utama
ANSI B29.1 Compliant
Full conformance to ANSI B29.1 standard ensures interchangeability with any brand of #120 roller chain and drive components available in the Australian market.
Induction-Hardened Tooth Profile
Precision tooth-flank hardening to HRC 50–60 extends service intervals by 3× and eliminates the chain-skip failure mode that plagues soft-tooth sprockets.
Type A / B / C Hub Options
Three hub styles cover every mounting scenario — from weld-on platewheels (Type A) to deep double-hub engagement (Type C) for maximum torque transfer.
Ex-Stock Availability
Standard tooth counts stocked in Australia for same-week dispatch, minimising equipment downtime during emergency replacements.
Compatibility & Selection
Compatible with ANSI #120 roller chain to ANSI B29.1 standard (pitch 1-1/2″, roller Φ 0.875″). Also available in double-strand (#120-2) and triple-strand (#120-3) for higher power applications. Finished bore and taper bore options available — specify shaft diameter at order. Request a selection guide from our engineers.

Pertanyaan yang Sering Diajukan (FAQ)
► What chain does the ANSI #120 sprocket use?
The ANSI #120 sprocket uses ANSI B29.1 #120 roller chain with pitch 1-1/2″. Do not use with ISO metric chain of similar pitch without verifying roller diameter compatibility.
► What is the difference between Type A, B and C sprockets?
Type A is a plain disc (no hub) for welding or bolting. Type B has a single boss on one side. Type C has bosses on both sides for maximum shaft engagement and torque capacity.
► Are double and triple-strand versions available?
Yes. #120-2 (duplex) and #120-3 (triplex) are available for higher torque drives. Please specify strand count when ordering.
► Can you supply with a specific finished bore?
Yes. Specify your shaft diameter and keyway dimensions at order. Standard lead time for finished bore is 5–7 days.
► Do you stock these in Australia?
Selected tooth counts are stocked locally for 2–5 day delivery. Contact our sales team to confirm stock availability for your specific requirement.
- Match bore to shaft diameter (H7/k6 tolerance recommended for press-fit applications).
- Position sprocket on shaft; secure keyway and set-screw per hub marking torque spec.
- Align with driven sprocket using a straight-edge across tooth faces within 0.5 mm.
- Thread ANSI #120 roller chain; close with a half-link or connecting link and orientate the open end away from the direction of travel.
- Set sag on slack strand to 2–3% of centre distance; recheck after 4 hours of loaded operation.
