Ridewell Suspensions has expanded its air ride suspension line with an integrated stub axle suspension system for heavy haul applications. The RAR-251 Stub Axle Air Ride Suspension contains two beam assemblies that can be integrated with a 32-in. track Ridewell axle configured with WABCO PAN 19 disc brake assemblies.
“The unique pivot design and excellent lateral stiffness of the RAR-251 suspension provides a significant increase in capacity for trailer manufacturers wanting a multi-tire configuration that provides a 40,000 lb. capacity per axle line,” says Bruce Barton, Ridewell’s director of engineering. “In addition, the air ride suspension offers a better ride quality for trailer owners seeking an alternative to mechanical trunnion suspensions.”
The initial release of the RAR-251 system is designed for a minimum 10-ft. wide trailer up to a 14-ft. or wider trailer installation. The RAR-251 accommodates 225-70R 19.5 and 245-70R 19.5 tire sizes at a 12-in. ride height. Purchasers can use their own hangers or Ridewell can provide a hanger specifically designed for their application.
Additional configurations include a 12.25-in. drum brake assembly for 17.5-in. tires and a Ridewell stub axle with a PAN 19 disc brakes configuration to accommodate a 22.5-in. wheel.
