Success Story - SPKGSPOA

SPKGSPOA heavy-duty flanged wheels for rail vehicles


The Customer

A manufacturer of shunters and rail vehicles.


The Challenge

The customer developed a road-rail vehicle with an unprecedented drive concept that is suitable for both rails and streets. For rail use, the vehicle required a flanged wheel, which features smooth rolling with high load capacities. With predetermined dimensions such as a diameter of 29.5 inches the aim was to be able to guarantee load capacities of 7.7 tons, as well as improved traction values and reduced noise emissions

Our Solution

Because the customer-specific requirements necessitated a special construction, we developed a welded wheel center made of 42CrMo4 steel with a welded support ring. We are able to achieve improved traction compared to steel-on-steel using a shrink-fit cast nylon press-on band, which also provides improved operational comfort.

Product advantages & technical information SPKGSPOA 750:

• The shrink-fit cast nylon press-on band ensures a high running comfort and improved traction performance • Additional fixing of the press-on band with multiple threaded bolts and a locking ring
• The reinforced steel wheel center allows load capacities of up to 7.7 tons • Optimal transmission of force with positive locking between the press-on band and wheel center
