New chain promises improved wear life in demanding conditions

BMG’s power transmission division has launched the Tsubaki Titan chain series which it says offers significant improvements in wear-life in demanding applications, including abrasive and dusty conditions.
“Selecting the right chain for every job is critical, especially in harsh conditions where dust and abrasive particles infiltrate moving parts and significantly shorten the lifetime of standard chain. This damage results in high costs caused by downtime, production loss, replacement parts and labour,” said Gavin Kirstein, Tsubaki Product Manager, BMG.
“Tsubaki Titan chain, which offers previously unobtainable wear-life in harsh conditions, combines key features of the existing premium Tsubaki GT4 Winner chain, with new specifications which have been designed to deliver extended wear performance.
“Advanced design features for the Titan series, not only extend service life of the chain, but also reduce maintenance costs and minimise downtime. Another advantage is the reduced frequency of swapping out old chain for new, which contributes to a significant reduction in the Total Cost of Ownership.”
Kirstein said an important feature of Tsubaki Titan chain is the use of seamless bushes that incorporate lube grooves. “These bushes, which are precision-made and perfectly cylindrical, ensure the smoothest possible operation to help minimise wear. Added to this, the specially designed lube grooves ensure oil is retained at the point of contact, where the chain needs it most. This limits the wear between pin and bush, significantly improving the wear life.”
He added that Tsubaki Titan pins have a special surface coating that provides an extra hard, yet low-friction surface, further extending service life.
For this new series, the Tsubaki development team has specified corrosion-resistant, nickel-plated outer link plates, which are used in combination with black oxide inner link plates, to provide an additional layer of protection against corrosion.
Tsubaki has also incorporated its reliable ring coined technology, which overcomes the problem of typical standard slip-fit connecting links, that are usually much weaker than other links. The process of ring-coining the connecting links ensures that the chain can be specified up to its full load capacity.
Standard Tsubaki Titan Chain is available from BMG in sizes 12B to 32B. Additional sizes, multi-strand and attachment options will be available on request.
Typical applications of this series include abrasive and dusty conditions, such as those found in timber mills, brick works, mining, and metal working, as well as in sugar and paper processing.
Kirstein said BMG is the only company in the world - outside of the Tsubaki organisation - with accreditation to provide a specialist assembly service for Tsubaki chain products. The company has a dedicated facility at BMG World in Johannesburg, where special attachment chains are assembled to exact requirements and delivered in less than one week.
Customers are able to specify a wide range of standard Tsubaki attachments on any suitable American (ANSI) or British (BS) chain product, of up to 50 m in length. There is no compromise in terms of component specifications and quality standards are guaranteed. BMG’s assembly service means customers don’t need to invest in expensive stockholdings of specialised attachment chains for a particular machine.
