Body Seals
Body seals cover the sealing found away from the powertrain — the gas struts that hold a bonnet, tailgate or cab tilt, and similar body-mounted assemblies. Small parts, but they hold gas pressure for years without any service. SES holds the range as an authorised SKF distributor, covering sub-group Gas spring seals; charge medium Nitrogen with a small oil charge for lubrication; materials NBR, PU, PTFE-faced sets; temperature Vehicle ambient extremes, cold to hot soak. Executions include gas spring seals. It is specified most often into cab tilt struts on tipper and tractor units and bonnet and tailgate struts on light commercial vehicles. Every part is genuine SKF through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Body Seals in the parts of a plant where this particular duty actually occurs. In practice that means cab tilt struts on tipper and tractor units, bonnet and tailgate struts on light commercial vehicles, access hatch and panel struts on plant machinery, and equally operator cab door and window struts on loaders, enclosure lids on generator sets and canopies, seat suspension and adjustment assemblies. What links them is the duty rather than the machine name — covers: Gas spring and body assembly sealing. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the SKF range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. The strut is outdoors and cycles only occasionally — A seal set built for long static dwell. Long idle periods, not stroke count, are what kill gas spring seals. Ambient swings from cold night to hot afternoon under a canopy — A compound with low compression set across the range. A seal that sets cold will not reseal when the strut warms and the charge bleeds away. The rod shows pitting or the chrome is flaking — Replace the strut rather than the seal. Once the rod surface is damaged there is no seal that will hold the gas charge. Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Never cut or drill a gas strut to dispose of it while it is charged. They are vented through a controlled port for a reason, and the rod leaves the tube fast enough to injure someone. Send the designation off the failed part and we will confirm the SKF equivalent and stock position.
