STEMFAST Axles of Ripponden, West Yorkshire is marketing its latest trailer axle (the prototype of which was seen at Tipcon) along with a. new mechanical suspension system.
The axle assembled from components sourced in Britain, has a design capacity of 10,170kg and weighs between 314 and 332kg (692 and 732 lb) depending on track specification. Girling Skidchek equipment can be added to the new design.
Shaft and S-cams are computer machined for greater profile accuracy while cam rollers and anchor pins have grease retaining reservoirs, prepacked with synthetic high melting-point grease.
As well as improving the axle beam design Stemfast uses a recessed five-segment spigoted hub.
Steel suspensions that complement the new range are also available, built to the company's patent Stronglight design. Single, tandem and tri-axle arrangements are offered with single or multileaf springs. In single leaf form these weigh 107, 228 and 360 kg respectively, while multi-leaf arrangements weigh 124, 261 and 398kg respectively.
