One of Europe’s largest producers of asphalt for road construction was using a roller chain to drive its conveyors, but this was only lasting for a short service period. So, the company turned to Tsubaki, which suggested its latest BS/DIN European premium chain, GT4 Winner.

This chain has four key features: Lube-grooved (LG) bushes hold oil at the point of contact which provides an internal reservoir for lubricant where the chain needs it most; Seamless and perfectly cylindrical bushes result in both better contact between the pin and bush and improved lubricant retention; Centre sink rivets for easy disassembly; and Ring Coined connection links that allow the chain to be specified up to its full kW rating.

Tsubaki offered to run a KG test and, for the purpose of this test, compared its GT4 Winner chain against the standard chain that had previously been used and a premier chain from the same manufacturer which uses chrome bearing pins for increased wear resistance. The chain was left in operation for 1750 service hours prior to measuring for elongation. The competitor’s premium brand had suffered 3.3% elongation while the

GT4 Winner was only 1.9% – this equates to 42% less elongation for GT4 Winner. In

comparison to the original chain – which had suffered from 3.5% elongation – Tsubaki’s solution was shown to offer 45% less elongation, a significant improvement and one that could double the service life of the chain, states the company.
