PLANETARY STEER AXLES
PSC1764 SERIES
PRODUCT SUMMARY
The AxleTech PSC1764 series planetary steer axle is engineered to meet the increasing powerful demands of the heavy-duty Rough Terrain Crane and various off highway market vocations. With an axle capacity range up to 50,000 lbs. (22,680 kg.) in R.T. Cranes, this axle covers a broad range of demanding vocational applications which include Reach Truck, and Log Loader at other axle rating capacities, among other common usages.
The PSC1764 planetary steer axle series offers a wide selection of overall gear reduction options; load capacities, brakes, and multiple tracks that can be tailored to your specific needs. Engineered for compatibility, with demanding traction conditions, the PSC1764 meets the trend of increased driveline torque, tire sizes, and loading requirements that provide an extra ruggedness for prolonged life.
A limited slip differential with a 2.0 bias ratio and NoSPIN® differential options are also available for improved traction vocational requirements. The PSC1764 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 single or dual caliper/wheel end Hydraulic Dry Disks are standard. Carrier input pinion mounted park brake options are also available. AxleTech International planetary steer axles are tough, dependable, and thoroughly proven under the most severe conditions.
AxleTech International is the former Rockwell Off Highway Products Division.
