When a standard straight-plate chain fails to handle lateral loads or attachment points in your conveyor system, engineers and DIY builders alike turn to curved plate roller chain. The double-sided single-hole design provides a secure, symmetrical attachment surface on both sides of the chain, making it the go-to choice for conveyor driving applications where consistent load distribution matters.
This roller chain features curved side plates with a single attachment hole on each plate, manufactured to ISO/ANSI roller chain standards. Available in types 06B, 06B-1, 08B-1, 10A, 12A, and 16A, with inner widths ranging from approximately 9.5 mm (3/8 in) to 12.5 mm (1/2 in) depending on the selected type. The chain pitch varies by type: 06B/06B-1 at 9.525 mm (3/8 in), 08B-1 at 12.7 mm (1/2 in), 10A at 15.875 mm (5/8 in), 12A at 19.05 mm (3/4 in), and 16A at 25.4 mm (1 in).
Typical use cases include light-to-medium duty conveyor belt drives, automated assembly line transport systems, agricultural machinery attachments, and DIY power transmission builds requiring a double-sided attachment roller chain for custom jigs or fixtures.
Single hole on each curved side plate allows secure bolt-through attachment on both sides of the chain — ideal for conveyor flights, guides, and custom fixtures.
Available in 06B, 06B-1, 08B-1, 10A, 12A, and 16A to match a wide range of sprocket pitches and load requirements across conveyor and drive applications.
The curved plate geometry reduces stress concentration at the attachment hole, extending service life compared to straight-plate attachment chains under cyclic loading.
Inner widths of 9.5 mm, 10.5 mm, and 12.5 mm (approx. 3/8 in – 1/2 in) available for 08B-1 type, ensuring correct roller-to-sprocket engagement without binding.
Engineered for continuous-duty conveyor driving applications including automated assembly lines, packaging equipment, and agricultural transport systems.

Match the chain type to your existing sprocket. The type designation indicates the pitch: 06B = 9.525 mm pitch, 08B-1 = 12.7 mm pitch, 10A = 15.875 mm pitch, 12A = 19.05 mm pitch, 16A = 25.4 mm pitch. Check your sprocket's stamped designation or measure the center-to-center distance between two adjacent teeth to confirm the pitch before ordering.
The inner width refers to the distance between the inner plates of the chain. This must match the face width of your sprocket teeth. For 08B-1 type, three inner width options are available. Select the width that corresponds to your sprocket specification to ensure smooth engagement and prevent side-loading on the chain plates.
The curved (bent) side plate distributes stress more evenly around the attachment hole compared to a flat plate. This reduces the risk of cracking at the hole edge under repeated tensile and bending loads, making it more durable in continuous conveyor drive applications where attachment bolts carry dynamic loads.
Standard roller chain is manufactured from carbon steel and is suitable for dry to lightly oiled indoor environments. For outdoor, washdown, or humid applications, we recommend selecting a stainless steel or nickel-plated variant if available, or applying a compatible chain lubricant regularly to extend service life. Contact us to confirm available finish options for your environment.
Yes — provided the sprocket pitch and tooth profile match the selected chain type. The curved plate and attachment hole do not affect sprocket compatibility; only the pitch and inner width matter for engagement. Ensure the sprocket face width accommodates the chain's inner width to avoid misalignment.
Quantity and length options vary by chain type. Please select your type and width above to see the available quantity options. For custom cut lengths or bulk orders, contact us directly and we will confirm availability and lead time for your specific requirement.
This chain type is widely used in conveyor systems for food processing, packaging lines, agricultural equipment (e.g., combine harvesters, seeders), automotive assembly, and general industrial material handling. The double-sided attachment makes it particularly useful wherever conveyor flights, scrapers, or pusher dogs need to be bolted directly to the chain.
