Dana Incorporated has announced the Spicer Dura-Tune center bearing, available on standard Spicer SPL driveshafts and heavy-duty Spicer 10 Series driveshafts.
The center bearing is designed for durability and tuned to provide powertrain vibration isolation and dampening for smoother, quieter operation on downsped drivetrains. It 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.
Its design helps to ensure proper installation and alignment throughout the life of the vehicle, delivering a more consistent ride while promoting drivetrain longevity. The new design also provides a more user-friendly installation, further reducing the possibility of future alignment-based issues.
The universal design of the Dura-Tune allows for the replacement of current standard SPL and heavy-duty Spicer 10 Series center bearing assemblies – as well as competitive products – and is available for retrofitting or as a replacement part through Dana's aftermarket business.
"The new Dura-Tune center bearing is a key innovation in increasing fleet productivity and maximizing vehicle up-time,” said Mark Wallace, president of Dana Commercial Vehicle Driveline Technologies. “It alleviates excessive drivetrain vibration and noise that can lead to unplanned downtime and driver fatigue and promotes the life of ancillary drivetrain componentry."
