Ridewell’s integrated stub axle suspension

Ridewell’s integrated RAR-251 Stub Axle Air Ride Suspension for heavy-haul applications contains two beam assemblies that can be integrated with a 32-inch track Ridewell axle configured with Wabco Pan 19 disc brake assemblies. The suspension’s pivot design and lateral stiffness help increase capacity for trailer manufacturers wanting a multi-tire configuration that provides a 40,000-pound capacity per axle line while offering an improved ride quality over mechanical trunnion suspensions.

The system is designed for a minimum 10-foot-wide trailer up to a 14-foot or wider trailer installation and accommodates 225-70R 19.5 and 245-70R 19.5 tire sizes at a 12-inch ride height. Customers can use their own hangers, or Ridewell can provide a hanger designed for their application. Additional configurations include a 12.25-inch drum brake assembly for 17.5-inch tires and a Ridewell stub axle with a Pan 19 disc brake configuration to accommodate a 22.5-inch wheel.
