TRW Ball Joints 'Sealed for Life'
There's always more than one way to do something - but at ZF Aftermarket, we use more than 100 years of experience, engineering expertise, and technical know-how to understand each of our parts and the way it operates.
LOW FRICTION TECHNOLOGY

|---|---|---|
HousingThe outer housing is manufactured using forged or cold formed steel for additional strength and reliability under the harshest of conditions. |
StudThe full ball metal stud is highly polished and encapsulated within a high strength polymer bearing for smooth articulation. This low-friction allows for free range of motion and provides smooth steering and suspension which restores the vehicle to original operational performance. The ball pin is either stainless steel or geo-met or similar coated for corrosion-free performance. |
Polymer BearingUnlike competitors who use metal, we utilize a high strength and resilient, low-friction glass fiber reinforced polymer bearing. This enhances road shock damping and provides smooth movement. Our bearings are made from either standard polymer (poloximethylene) known asthe POM design, or high temperature polymer (polyetheretherketone), known as the PEEK design. The strength of the polymer bearing can absorb the toughest road shocks and retract back to the original shape without loss of steering or suspension feel. |
WE STAND FOR SAFETY AND DURABILITY
TRW parts go through various types of testing before hitting the road:
- Independent endurance testing (500 cycles) at LBFTest institute in Germany
- Full measurement/drawing technical review by TRW engineering
- In-house testing for Rotational & Articulation Torque and Pull/Push out test
- Independent factory audits to ensure all processes are being followed
In addition to the above, we also do:
- Acoustic measurements to ensure driver comfort
- Environmental resistance tests for all weather conditions
- Road testing at TRW tracks around the world
