Dana has enhanced its Spicer Life Series (SPL) Model 250 universal joint assembly to provide improved product performance and durability. Designed to meet the needs of new low-emission, high-efficiency Class 8 trucks, the SPL-250 offers more than a 40% percent improvement in dynamic bearing capacity to create a driveline with 70% more power density compared with it nearest competitor, the company says. The assembly utilizes a new bearing package that includes larger needle bearings for increased capacity, a special Viton synthetic seal for improved grease retention and serviceability, and a thermoplastic seal guard to exclude contaminants. A new premium synthetic lubricant provides further improvement in bearing life through the initial 3-year/350,000-mile lubrication interval. The assembly is also offered with the Spicer Quick Disconnect feature, making it easier to service the powertrain.
