Main description

The 04B-2 DOLZAMET roller chain is a precision duplex power transmission component designed for applications requiring increased load capacity, stable operation and reliable torque transfer in compact mechanical systems.

A roller chain is a key element in power transmission systems, transferring motion between shafts through sprockets. The 04B-2 designation follows the BS and ISO standard, where 04B indicates a pitch of 6 mm and the -2 suffix defines a duplex construction with two parallel strands. This double row design significantly increases strength and resistance to elongation compared to single row chains.

The 04B-2 DOLZAMET chain is used in applications where higher durability is required but installation space remains limited. Its compact dimensions combined with enhanced load capacity make it an efficient solution for precision and dynamic drive systems.

Construction and design

The 04B-2 DOLZAMET roller chain consists of two parallel rows of links made up of rollers, pins, bushings and side plates.

The duplex configuration distributes load across two strands, reducing stress on individual components and improving overall durability. Precision manufacturing ensures smooth engagement with sprockets and consistent power transmission.

The materials used provide good resistance to wear and reliable performance in continuous industrial operation.
