Sachs CV shock absorbers with plastic dust cover now available

Plastic protective tube design reported to have advantages over metal protective tubes

ZF Aftermarket has confirmed that it is increasing the service life of commercial vehicle Sachs shock absorbers with the addition of plastic protective tubes for the aftermarket in addition to original equipment.

The mounting of the shock absorbers with plastic dust covers is carried out in the same way as shock absorbers with a metal cover.

ZF says the correct arrangement of the parts for the shock absorber mounting (pin joints/shock absorber bearings) must be observed.

A ZF spokesperson said: “As a safety-relevant spare part, the shock absorber together with the spring forms the connecting link between the wheel suspension and the chassis.

“It reduces the vibrations of the chassis spring, slows it down and ensures optimum road contact.

“Sachs commercial vehicle shock absorbers provide optimum driving comfort and effectively relieve the vehicle and driver, while offering maximum transport safety.”

Shock absorber mountings, steering and rubber-to-metal parts should be checked at every inspection.

It is advisable to lightly grease the fastening bolts of ring joints.

Rubber-to-metal parts should, however, be protected against grease.

The spokesperson added: “What should be avoided when installing a shock absorber with a plastic dust cover is the counter-holding on the protective tube itself, which is not necessary for correct professional installation.”

Shock absorbers for commercial vehicles should generally be checked and replaced if necessary after 250,000 km at the latest.

It is recommended that the surrounding components also undergo a professional inspection.

In this way any defective components in the vicinity of the shock absorbers can be detected in good time and expensive downtimes avoided.

The range of dampers offered by ZF Aftermarket under its Sachs brand includes classic dampers as well as CDC dampers, which adjust the damping hardness in real time to the respective driving situation.

Also available are cab dampers with standard or air springs as well as cabin air levelling module (CALM) and axle dampers for trailers.

Another highlight in the ZF Aftermarket portfolio are the Sachs air spring damper modules, which as a compact unit represent an alternative to the usual installation of dampers and air springs side by side.
