A wheel and axle for a railroad vehicle can weigh between 11 and over 400 pounds. The assembly’s total weight varies on the manufacturer and the type of wheel and axle used to create it.
A railcar may utilise either a regular wheel and axle assembly or a stub axle, which contains additional components such as an axle tube, bushings, and other parts. Rail cars are propelled by stub axles in regions with height, width, or length limits, such as mines. Aluminum and steel stub axle assemblies weigh between 11 and 20 pounds, far less than typical rail components. These stub axles have an average load capacity of 2,500 pounds.
Standard steel and ductile alloy wheel assemblies might weigh between 235 and 480 pounds. The average load capacity of the lesser assemblies is 10,000 pounds, while the average load capacity of the heavier assemblies is 40,000 pounds.
The assembly’s mass is dependent on the type of wheel utilised. For instance, KLW wheels alone might weigh between 363 and over 2,300 pounds. However, rail car wheel weights often represent either the weight of the wheel assembly as a whole or the maximum load weight the assembly can support, as opposed to the weights of the individual wheels and axle.
