The AxleTech SPRC4806 tandem planetary rigid axles are engineered to meet the extra toughness demanded by the OEM's in today's demanding environment. When you couple rough terrain with heavy loads and adverse weather conditions, you need the strength and support of AxleTech's planetary tandem axles. The SPRC4806 has the capability to meet the most severe vocational duty cycles and provide productivity uptime that converts directly to the end-user productivity.

Log haulers, truck cranes, dump trucks, heavy equipment transporters, and special purpose vehicles work in some of the most grueling environments in the world. AxleTech tandem planetary axles are designed with these conditions in mind. The SPRC4806 has capability of up to 1,000,000 lb (453,600 kg) in gross combination weights (GCW) dependant upon specific vocational duty cycle requirements. A balanced gearing design puts more power at the wheel ends. This reduces torque and stress on axle shafts and carrier/differential gearing, directly contributing to longer component life and reduced maintenance costs.

The SPRC4806 has a wide selection of features, both standard and optional, available to provide the heavy-duty tandem that is able to be optimized for your specific vocational requirements and makes this tandem the product of choice. A listing of standard features include high capacity hypoid gearing, crowned planet gears, wheel end planet gears mounted on tapered bearings and rugged high strength steel axle housings. Optional features that include high capacity cam brakes, carrier differential options, inter-axle differential with a pressurized oil lubrication system, single or dual style wheel hub mountings, and a wide range of overall axle ratios are available to be allow you to optimize the SPRC4806 to your specific vocational requirements.

In addition, extra axle housing magnets provide for reduced metallic contamination between oil lubrication intervals. An upgraded spindle nut retention mechanism is also provided by AxleTech for rugged operations.

AxleTech's special axle shaft manufacturing process produces high strength and shock resistant axle shafts to withstand the torsional stress requirements of large engines and transmission low gear operations.
