Dana Incorporated today introduced its new Spicer® S172 series single drive axle for Class 7 and 8 vehicles. The new product retains the robustness and strength of the existing S170 single drive axle, but weighs more than 60 pounds less. It is yet another example of Dana’s commitment to optimizing fleet uptime with lightweight but durable product offerings.
The axle is crafted for 4×2, 6×2, and 8×2 applications up to 25,000 lbs. (11,340 kg) GAWR. It offers a broad range of gear ratios, from 3.07 to 6.14, and features a low hypoid offset with High-Power Density™ AdvanTEK® gearing to drive maximum efficiency. The high-strength pinion bearings allow for greater lifespan under heavy loads, improving durability and overall performance. In addition, a passive lube management system requires less lube while utilizing a patented meter to optimize the amount of lube flow to the high-efficiency bearings.
The single drive axle can also be paired with the Dana tag axle as part of the Spicer® EconoTrek™ tandem axle, a durable, lightweight 6×2 configuration that offers increased fuel economy, improved performance, and reduced maintenance for heavy-duty linehaul tractors. This system is up to 3 percent more efficient and up to 380 pounds lighter than typical 6×4 offerings.
“Dana engineers are continuously examining innovative ways to improve our existing products,” said Mark Wallace, president of Dana Commercial Driveline Technologies. “We were able to build upon the advanced features of the S170 and make it lighter without sacrificing its industry-proven durability and efficiency. We remain a company committed to finding a better way to address the needs of our customers and the commercial-vehicle market.”
Dana will present a comprehensive lineup of driveline technologies and other solutions for commercial vehicles in booth 1005 at the 2018 Technology & Maintenance Council (TMC) Annual Meeting & Transportation Technology Exhibition this week.
