120-3 Roller ChainTriple 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 120-3 roller chain is dimensionally manufactured per ANSI B29.1 and ISO standards so it directly interchanges with other manufacturers. We stock Economy Plus and Premier series of #120-3 triple roller chain. Check out the chart below to see the differences between each one.
Series | Tensile Strength | Working Load | Solid Rollers | Solid Bushings | Heat-Treated | Shot Peened | Hardened Pins | Pre-Stretched |
|---|

| 102,000 LBS | -- | Y | N | Y | Y | N | Y |

Note: All of our ANSI 120-3 triple roller chains are supplied with solid rollers for increased long-term performance, regardless of quality level.
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.
