What are rubber bellows?
A rubber bellows can be mounted on our gas springs and ensures that the piston rod is protected against impurities and dirt. This protection extends the life of the gas spring. One end of the rubber bellows is attached over the cylinder. The other end is attached to the piston rod just under the thread. The gas spring can still move unhindered and the stroke length is minimally reduced by the distance the rubber is mounted onto the piston rod. The rubber bellows can withstand UV light and oil, and can be used in all types of environment.

Material
Rubber bellows are made from NBR rubber, which is resistant to UV light, salt and oil.
Theoretical operating temperature between -20 °C to +60 °C.
Tolerances
The L0 measurement (unloaded length) is for guidance only. The rubber bellows by design can be pulled and pressed, and so change length.
Variations in the L0 length have no impact on the usefulness of the bellows.
The bellows should not scrape/press against any other object, as wear will then cause the bellows to break.
Fitting And Use
When fitting bellows, use the length of the compressed bellows. This length is given in our table (Bm).
The bellows must be fitted before the end fittings are fitted to the piston rod.
The bellows are primarily designed for gas springs with threads, but can also be fitted to gas springs with welded loops.
The bellows must be fitted to the cylinder X number of mm (Bm) from the end of the cylinder, where the piston rod emerges.
- There is a line marked on the cylinder X number of mm (Bm) from the end of the cylinder, where the piston rod emerges.
- The bellows are guided with the largest diameter down over the piston rod and over the cylinder towards the line.
- The bellows are secured to the last piece of rubber on the cylinder using the strip provided.
- The bellows are secured to the piston rod using the strip provided on the last piece of rubber when the end of the rubber is just under the thread.
- Cut off the remainder of the strip.
