Description
Rail wagon bearing adapters & Truck Assembly.
Selecting the Correct Frame
Adapter Frame adapters are used to fit bearing assemblies to various types and sizes of truck frames. The most popular kinds are narrow, wide and composite adapters.
Similar frame adapters are available or may be designed to adapt the bearing to all types of trucks.
Frame Key Recommendations
SCHBER recommends using frame keys on all cars. Frame keys keep the bearing and adapter in place during operation and limit the amount of possible vertical separation between the bearing and adapter during unusual operating situations.
The target clearance between the key and cup OD should be 1/16”-3/16”. Refer to the current version of the AAR Manual Section H, Standard S-720.
Truck Disassembly
When disassembling a truck, use the opportunity to inspect the roller bearings and associated parts as outlined in the service inspection section.
