Dana has unveiled its Spicer Dura-Tune centre bearing, available on standard Spicer SPL and heavy-duty Spicer 10 Series driveshafts.

The new centre bearing is tuned to provide powertrain vibration isolation and dampening for reduced driver fatigue. The unveiling was one of several new product launches made at the 2019 Technology and Maintenance Council (TMC) Annual Meeting and Transportation Technology Exhibition.

The new Dura-Tune centre bearing addresses noise, vibration, and harshness levels associated with the significantly higher drivetrain torque stresses and unique vibration frequencies created by engine downspeeding and chassis lightweighting.

“We’ve leveraged our experience and technology solutions from proven Dana vehicle driveshaft systems to bring this solution to the commercial-vehicle market,” said Mark Wallace, president of Dana Commercial Vehicle Driveline Technologies president, Mark Wallace.

“The new Dura-Tune centre bearing is a key innovation in increasing fleet productivity and maximising vehicle up-time. It alleviates excessive drivetrain vibration and noise that can lead to unplanned downtime and driver fatigue and promotes the life of ancillary drivetrain componentry.”

The universal design of the Dura-Tune allows for the replacement of current standard SPL and heavy-duty Spicer 10 Series centre bearing assemblies – as well as competitive products – and is available for retrofitting or as a replacement part through Dana’s aftermarket business.

“Understanding the dynamic relationship between the centre bearing and the overall performance of the driveshaft is imperative, regardless of whether the vehicle was just assembled by one of the industry’s premier OEMs or has been on the road for an extended length of time,” added Wallace.
