Features & Advantages
1
Reduced Component Count
Double-pitch design allows twice the pitch between links — fewer sprockets and chain joints per metre of conveyor, lowering total drive cost by up to 30%.
2
Hardened for Conveyor Demands
Induction-hardened tooth flanks to HRC 50–60 resist the abrasive wear patterns typical of slow-speed, high-load conveyor applications.
3
⚖️ Lower Weight, Same Pitch Circle
Compared to equivalent standard-pitch sprockets, double-pitch variants are lighter, reducing rotational inertia and bearing loads in start-stop conveyor cycles.
4
Stock Bore for Quick Fit
Standard stock bore machined to drawing allows rapid installation on common shaft diameters — critical for minimising conveyor downtime in logistics and food processing facilities.

Kundrecensioner
Greg H. ★★★★★ Australien
“Replaced worn double-pitch sprockets on our carton conveyor with NK2080SB / NK2100SB — installation was straightforward and the conveyor runs quieter than before.”

Vanliga frågor
► Can I use a double-pitch sprocket with a standard single-pitch chain?
No. Double-pitch sprockets are designed exclusively for double-pitch conveyor chain. Using standard single-pitch chain on a double-pitch sprocket will cause incorrect meshing, rapid wear, and potential chain derailment.
► What is the difference between RB and SB suffix?
RB indicates round-barrel rollers (standard for conveyor chain). SB indicates small-barrel (slimmer roller profile). The chain and sprocket suffix must match.
► Are finished bore versions available?
Yes. Specify shaft diameter and keyway at order. Standard lead time for finished bore double-pitch sprockets is 5–7 days.
► What is the maximum shaft speed for double-pitch sprockets?
Double-pitch sprockets are optimised for slow speeds (typically 10–60 m/min chain speed). For high-speed drives, use standard single-pitch chain instead.
► Are stainless steel double-pitch sprockets available?
Yes, SS304 double-pitch sprockets are available for food-grade conveyor applications. Contact us for lead time and pricing.
- Verify shaft diameter against stock bore dimension; machine finished bore if required.
- Position sprocket on shaft and align with the opposing end of the conveyor run using a laser or wire-line method.
- Install double-pitch conveyor chain; set tension with 1–2% sag on the return strand.
- Operate the conveyor at slow speed before full-load; check for chain-to-sprocket tracking alignment.
