METAL UPPER RING AND CLOSING CAP ON LINK STABILISERS

Share

DID YOU KNOW: Advice for the professional

Link stabilisers endure repeated push and pull movements in operation. Metal to metal component contact significantly increases wear resistance against these forces.

SYNTHETIC UPPER RING

The purpose of the upper ring is to ensure a strong and durable seal of the dust boot around the ball pin to prevent the intrusion to the housing of contaminants such as sand, dust or water.

Due to the repetitive articulations, a synthetic upper ring progressively loses its original clamping properties and contamination eventually leads to premature wear or damage of the plastic bearing and degraded lubrication. Increased play of the ball pin is symptomatic of component failure.

MOOG uses a metal upper ring on all its link stabilisers. This maintains a performant seal even at extreme articulation angles, throughout the service life of the part.

Another weak point of some link stabilisers is the use of a plastic closing cap. These can wear prematurely and clearance can develop, particularly following impact caused by a pothole for example.

MOOG uses a metal closing cap on all link stabilisers.

For a plastic closing cap to have the strength of its metal equivalent it would have to be much thicker with a larger housing.

MOOG achieves greater strength and performance whilst maintaining an unchanged ball diameter and fully conforming to OE specifications.
