A gas spring that loses preload after 80,000 cycles is usually sent back as a spring problem. In most teardowns the rod is still straight, the nitro...

A gas spring that fades on a durability bench rarely has a gas problem. The oil has crossed the rod seal. An unbalanced damping seal presses harder ...

A silicone rubber ring is not a general-purpose industrial seal. It is a specialized elastomer that earns its place where temperature extremes, weat...

The 7.3mm pneumatic-grade seal is the most critical interface between compressed air and the mechanical components of a gas spring or damper. When t...

A gas spring that runs at 12 MPa with a 1.5 mm radial gap will destroy an unreinforced elastomer lip seal in a matter of hours. This failure pattern...

A gas spring in a recliner seat starts to leak at around cycle 8,000 in a production hall with 80 percent humidity. The usual suspect is the chrome ...

When an L-Shaped Oil Seal Ring Is the Right Choice An engineer working on a compact gas spring noticed oil seepage along the rod after extended cycli...

A damping oil seal rarely fails with a loud warning. The first visible sign is often a thin film of oil on a shock absorber rod, followed by a slight...

Inside a gas spring that holds a hatch open on an agricultural machine, the seal has to move, hold pressure, and survive dust and temperature swings ...

An O-shaped oil seal ring can be one of the most forgiving sealing elements in a machine, but it fails quickly when the basics are wrong. The contact...
