Simplex Half Links

Transmissions Roller Chains British Standard Simplex (Single Row)

British Standard Simplex Half Links, also known as crank links or offset links, are essential components used to adjust roller chain length by adding a single pitch increment when a full link would be too long. These half links enable precise chain tensioning and are ideal for applications where exact chain length is critical for optimal power transmission. We stock a comprehensive range of simplex half links from trusted manufacturers Dunlop and Donghua, available in various sizes with pitches ranging from 8mm (05B-1) up to 38.1mm/1.1/2inch (24B-1). Our selection includes both standard and cottered style options for larger sizes, with specifications including inner widths from 3mm to 25.4mm and roller diameters from 5mm to 25.4mm. Whether you need to modify an existing chain drive or require replacement components for maintenance, our half links are manufactured to British Standard specifications ensuring compatibility with your existing simplex roller chain systems. If you need assistance selecting the correct half link for your application, please contact our technical team who will be happy to help.
