Thinner, lighter Vespel® SP-21 thrust washers replace all-metal needle bearings in a new 7-speed AT for rear-drive vehicles
Vespel® thrust washers have been selected to replace larger and heavier metal thrust needle bearings positioned between the clutch casing and aluminum transmission housing.
The Challenge
Good mileage, compact design and fun to drive!

Vespel® SP-21 thrust washers are thinner and lighter than comparable metal thrust needle bearings, helping to reduce the AT’s overall size and weight. In addition, Vespel® SP-21 thrust washers have been selected because they have the ability to rotate directly against the aluminum housing, allowing a reduction in the number of parts and an easier assembly process.
Key Advantages
Superior resistance to heat and wear. Capability of direct contact with aluminum components
Vespel® thrust washers have demonstrated many years of superb reliability in transmission applications due to:
