ISO 28B-1 Sprocket

ISO 28B-1 Sprocket

这 ISO 28B-1 sprocket (1-3/4″×29.2″, 44.450 mm pitch, DIN 8187) is engineered for medium-to-heavy industrial chain drives requiring high precision and long wear life. With C45 carbon steel construction, induction-hardened teeth (HRC 50–60), and tooth counts from Z=6 to Z=32, it solves premature wear and chain-skipping failures on conveyors, agricultural machinery, and processing equipment throughout Australia.

常问问题

►  What chain does the ISO 28B-1 sprocket require?
ISO 28B-1 roller chain to DIN 8187 / ISO 606, with pitch 44.450 mm and roller diameter 27.94 mm.
►  Are finished bore and taper-sleeve versions available?
Yes. We supply finished bore (machined to your shaft dimensions) and taper-sleeve versions accepting standard bush sizes. Specify requirements at order.
►  Do you supply duplex and triplex versions?
Yes. 28B-2 (duplex) and 28B-3 (triplex) are available for higher torque applications. Contact us for availability by tooth count.
►  What is the tooth hardness?
Tooth flanks are induction-hardened to HRC 50–60. Core hardness is 28–34 HRC. We can provide hardness test certificates on request.
►  What is the minimum order quantity?
10 pieces for standard sizes from stock. Custom tooth counts: MOQ 50 pieces, lead time 7–14 days.
  1. Verify bore or taper bush size matches shaft; clean mating surfaces.
  2. Align sprockets to within 0.5 mm lateral offset using a precision straight-edge.
  3. Install ISO 28B-1 chain and set slack-side sag to 2% of centre distance.
  4. Torque all fasteners to specification; check alignment after initial run.
  5. Re-lubricate every 200 operating hours with appropriate chain lubricant.
