08B roller chain is the half-inch pitch British-standard chain used across conveyors, packaging lines and light industrial drives – and the chain most imported equipment is specified around, which is why KaiVoy sells it by the metre: replace a worn run without buying a full box.

Pitch is the identity: 12.7 mm centre-to-centre between pins. An 08B chain runs on 08B sprockets and on the gear motors fitted to KaiVoy sensor and drive equipment alike – the chain does not care which machine it turns.
什么情况该换链
- Measure elongation, not appearance: rollers can look clean while the pitch has stretched. Compare the pin-to-pin length of a stretched section against a new metre of chain; a worn BS chain rides the sprocket teeth out before it visibly fails.
- Replace the sprockets with the chain: a new chain on elongated sprocket teeth wears to the old pitch profile within weeks – budget both or the metre is wasted.
- Mind the joining hardware: connecting links and half links are orderable with the run; a hammered side plate is how good chain gets written off.
维修备货怎么订
The 100 m MOQ is a drum, not a sample – enough for a maintenance season on one line or a mixed container with automation components. State the destination port and we quote FOB, CFR or CIF with the drum count on the packing list.
常见问题
08B 和 1/2 英寸节距的 ANSI 链一样吗？
No – the pitch matches but the plate height, roller diameter and pin length differ between BS 08B and ANSI 40 chain. Match the standard stamped on the existing chain before ordering.
链轮能随链条一起订吗？
Yes – sprockets are in the options list alongside connecting and half links; send the tooth count and bore with the enquiry.
价格怎么报？
Request a quote – Per metre against quantity, FOB / CFR / CIF by destination port – the drum count and link hardware go on the packing list.
