Description Technical Specs
 
03B metric roller chain is the smallest and most precision metric chain within the ISO British Standards classification. We typically supply 03B-1 chain in 10ft boxes but it is also available in 5-meter boxes and larger length reels upon request. Our metric chains are made utilizing heat-treated precision components for maximum performance and durability, they are also shot-peened and pre-stressed at the factory to improve shock load capacity and reduce chain stretch during use.
