Alcoa and SAF-Holland Develop Flangeless Wheel
Alcoa and SAF-Holland have announced that they are working together to develop a new trailer wheel which can be mounted without a separate hub flange. The lightweight forged wheel weighs in at just 28.5 kilos and its size is 22.5 x 11.75. Maximum load per wheel comes in at 4500 kilos. The offset is 60 mm and the disc thickness is 35 mm.
The advantage of this new SAF 60 ONE development is a weight saving of 8.7 to 18.7 kilos per axle end, therefore nearly 60 kilos per trailer, which is achieved by integrating the hub flange as an integral part of the aluminium wheel. The wheel is mounted with bolts, replacing the classic wheel nuts and studs.
The decision about whether to take this wheel into production, will reportedly depend on the market response after the IAA show, where the new development will be displayed on the SAF-Holland and the Alcoa stands.
