The AxleTech PSC5494 planetary steerable axle is engineered to meet the increasing powerful demands of the heavy duty rough terrain crane and logging reach truck vocations, with an axle capacity of up to 90,000 lb (40,860 kg).

The PSC5494 planetary steerable axle series offers a wide selection of overall gear reduction options that can be tailored to your specific needs. Engineered for compatibility with demanding traction conditions, the PSC5494 meets the trend of increased driveline torque, tire sizes, and loading requirements that provide an extra ruggedness for prolonged life. A DCDL (Driver Controlled Differential Lock), limited slip differential with a 2.0 bias ratio and NoSPIN® differential options are also available for improved traction vocational requirements. 

The PSC5494 design helps reduce OEM/end-user maintenance costs. A standard input pinion unitized seal reduces the likelihood of oil leaks. Permanently lubricated steering axle shafts are standard; eliminating this maintenance requirement. Extra axle housing magnets are optional to help reduce any metallic contamination between scheduled lubricant change intervals. 

Wheel mounted dual caliper/wheel end hydraulic dry disc is standard. Carrier input pinion mounted park brake option is also available.
