Moulded vehicle parts oust aluminium
originals
Thrust ring components for heavy duty vehicle transmissions moulded from a high performance Peek material offer less surface abrasion and longer life than the aluminium components they replace.
Thrust ring components used in heavy duty vehicle transmissions are moulded from a high performance Peek material by Minnesota Rubber/QMR Plastics resulting in less surface abrasion and longer life than the aluminium components they replace During operation, the thrust ring component acts as a rotating planetary carrier for helical shaped ring gears in transmission assemblies

Cover assembly cuts build time and avoids leaks
Eliminating leaks in hydrostatic pump controllers is made possible with a pressure tested cover assembly of six components from Minnesota Rubber/QMR Plastics.
The thrust load forces generate heat, potential wear and abrasion.
With the new Peek component design from Minnesota Rubber/QMR Plastics, thrust ring durability has been increased significantly while maintaining required performance levels.
According to Minnesota Rubber/QMR Plastics, the material compound includes a high percentage of Peek for its high temperature resistance of 204-232C, carbon fibre for high wear resistance and PTFE for low friction qualities.
The new thrust ring component design also provides assembly benefits.
The previous aluminium component design had two locating holes which required riveting operations.
Accurate alignment was required to avoid wasted components and possible performance issues.
By contrast, the new Minnesota Rubber/QMR Plastics designed component features self-aligning extensions at each end that press fit quickly and accurately into the transmission assembly ring gears.
Potential alignment issues were eliminated along with scrapped components.
In addition to costing less than aluminium components, requiring less assembly time and providing longer operating life, the Minnesota Rubber/QMR components weigh 50% less, an important consideration in today's automotive designs.
