140-4 Roller ChainQuadruple strand roller chain (also known as triplex) is typically used in heavy-duty industrial power transmission applications that require a high-strength ANSI roller chain. Our 140-4 roller chain is dimensionally manufactured per ANSI B29.1 and ISO standards so it directly interchanges with other manufacturers. Additionally, all of our 140-4 roller chains we supply are supplied with solid rollers regardless of quality series, and solid bushings when in the Premier series.
Split vs. Solid
Solid rollers drastically increase the overall working life of a roller chain because it is the first and primary point of contact between the chain and sprocket. Split rollers have the tendency to deform quickly and cause further wear.
Solid bushings decrease the amount of internal friction on the roller chain and even after long-term use, solid bushings keep their form. This further increases the working life and durability of a chain, and will greatly perform superiorly in medium to high-speed applications.
