When a broken or worn roller chain brings your conveyor, drive system, or machinery to a halt, every minute of downtime costs you. Engineers, maintenance technicians, and serious DIYers who work with 08B-1 pitch roller chains need a connecting link that installs quickly, holds securely, and resists the corrosive environments that destroy standard carbon steel hardware.
This 40# 08B-1 stainless steel roller chain hollow pin connecting link is engineered for standard 08B-1 (ANSI #40) roller chains with a 12.70 mm (1/2 inch) pitch. The hollow pin design allows the clip or cotter pin to seat firmly, ensuring the link stays locked under load. Constructed from stainless steel for corrosion resistance, the link is compatible with chains conforming to ISO 606 / DIN 8187 08B-1 specifications.
Typical use cases include agricultural machinery chain repair, food-processing conveyor maintenance where corrosion resistance is critical, and general industrial drive chain replacement — all scenarios where a dependable 08B-1 hollow pin connecting link for stainless steel roller chain is non-negotiable.

This link is designed for 08B-1 (ANSI #40) roller chains with a 12.70 mm (1/2") pitch. Check the chain pitch stamped on your existing chain or sprocket documentation. If your chain is 08B-1 single-strand, this link will fit. If you are unsure, measure the center-to-center distance between two adjacent pins — it should be 12.70 mm.
A hollow pin connecting link uses a clip or cotter pin inserted through the hollow pin to lock the link in place. This allows tool-free or minimal-tool field installation and removal, making it ideal for maintenance situations where a chain press is not available. Solid pin links typically require pressing and are more permanent.
Stainless steel connecting links offer good tensile strength suitable for light-to-medium duty drive and conveyor applications. For exact load ratings, refer to the variant specifications or contact us to confirm suitability for high-load or shock-load environments. Stainless steel is particularly advantageous where corrosion resistance outweighs the need for maximum tensile strength.
Stainless steel provides significantly better corrosion resistance than standard carbon steel roller chain hardware. It performs well in wet, humid, and mildly corrosive environments. For highly aggressive chemical environments (e.g., strong acids or chlorides), contact us to confirm the appropriate grade of stainless steel for your conditions.
ANSI #40 and ISO 08B-1 chains share the same 12.70 mm pitch, but there are minor dimensional differences in roller diameter and inner width between the two standards. This link is specified for 08B-1. If you are running a strict ANSI #40 chain, please verify the inner width and roller diameter against your chain's specifications before ordering, or contact us to confirm compatibility.
Thread the outer plates onto the chain ends, insert the hollow pin through the aligned holes, then slide the clip (spring clip or cotter pin) through the hollow pin's retaining groove or hole. Ensure the clip's open end faces away from the direction of chain travel to prevent it from catching and disengaging during operation. No chain press is required.
In most cases, yes — a single connecting link is all that is needed to close a roller chain loop after cutting out a damaged section or joining two chain ends. This listing includes 1 piece, which covers a standard single-joint repair. If you need to repair multiple chains or want a spare on hand, simply add the quantity you need to your cart.
