Cost-efficient operation:

SACHS dampers for commercial vehicles.

SACHS Dampers for CVs

SACHS dampers ensure the reliable and cost-efficient operation of commercial vehicles. They are extremely durable, enable optimal driving comfort and effectively relieve the strain on vehicles and drivers. At the same time, they offer the highest level of transport safety, even in the case of sensitive payload.

In addition to conventional dampers, the SACHS portfolio includes driver's cabin dampers, axle dampers for trailers and suspension springs.

Dampers for comemrcial vehicles should be inspected and, if required, replaced after 250,000 km at the latest.

Damage evaluation

  • Leakage and possible causes

    Although a damper may appear to have a leak, this may not in fact be the case. A certain amount of "perspiration" is normal, and even necessary to lubricate the piston rod seal. Never assess the damper after driving in the rain; the dampers should be dry.

  • Noise and possible causes

    Noise during spring compression does not necessarily come from defective dampers.

    Therefore, check:

    • axle suspension
    • stabilizer rubbers
    • caps
    • and, of course, check whether the noise is caused by objects in the load compartment.

    • and, of course, check whether the noise is caused by objects in the load compartment.
  • Rubber joints worn and torn

    Cause:

    • Normal wear due to high mileage.
    • Wear due to sand (abrasive effect).
    • Wear due to driving with ride height too high or incorrectly adjusted air spring level setting.

    Consequence:

    • Noises (rattling, knocking)

    Cause:

    • Normal wear due to high mileage.
    • Wear due to sand (abrasive effect).
    • Wear due to driving with ride height too high or incorrectly adjusted air spring level setting.

    Consequence:

    • Noises (rattling, knocking)
  • Thread impressions in bush
  • Damage – Impact damage

    If the damper is damaged, this was caused by force – through an accident or an installation error.

    Therefore, check:

    • Damage on axles and damper anchorage
    • Perform wheel alignment.

FAQ about dampers

  • Additional components

    Defective dampers lead to faster wear of adjacent components. Therefore, inspect the suspension strut mounts, service kits, and suspension springs during each damper check. When replacing the damper, also replace the suspension strut mounts and service kits.

  • Transport and storage of dampers

    In case of twin-tube dampers, air can enter the working space when transported or stored in horizontal position. The air can be easily and effectively removed by compressing and stretching the damper several times in succession. However, the damper independently vents the air shortly after its installation.

  • Assembly and anchorage of dampers

    When securing the damper (stud joints/suspension strut mounts), please pay attention to the correct alignment of the parts. Check the damper anchorage, steering parts and rubber-to-metal components during each inspection. In this context, it is advisable to slightly grease the mounting bolts of ring joints. Caution: Protect rubber-to-metal components from grease!

  • False alarm

    Underbody protection and dirt from the road sticking to the damper are often wrongly diagnosed as leakage.
