O-rõngas
O-rõngad säilitavad tihendi kontaktjõu tänu nende radiaalsele või aksiaalsele deformatsioonile tihendi korpuses kahe komponendi vahel. Memi Varustaja OÜ tarnib laias suuruses ja erinevatest materjalidest O-rõngaid, mis muudavad need sobivaks mitmesuguste töötingimuste ja rakenduste jaoks. Neid on lihtne paigaldada ja need võimaldavad lihtsa ja kulutõhusa tihendikorpuse disaini.

Acrylonitrile-butadiene rubber – NBR
Among standard seals such as O-rings and radial
shaft seals, NBR is the most widely used material.
The reasons for this are good mechanical properties, high abrasion resistance, low gas permeability
and the high resistance to mineral oil based oils and
greases.
NBR is a copolymer of butadiene and acrylonitrile. Depending on the application, the content of
acrylonitrile can vary between 18% and 50%. Low
ACN content improves cold fl exibility at the expense of the resistance to oil and fuel. High ACN
content improves the resistance to oil and fuel
while reducing the cold fl exibility and increasing
compression set.
To obtain balanced properties, our standard NBR
materials have an average ACN content around
30%.

NBR has good resistance to:
mineral oil-based oils and greases
aliphatic hydrocarbons
vegetable and animal oils and fats
hydraulic oils H, H-L, H-LP
hydraulic fluids HFA, HFB, HFC
silicone oils and silicone greases
water (max. 80°C)

NBR is not resistant to:
fuels with high aromatic content
aromatic hydrocarbons
chlorinated hydrocarbons
non-polar solvents
hydraulic fluid HFD
glycol-based brake fluids
ozone, weathering, ageing, UV resistance

Application temperature range:
Standard types -30°C to +100°C (short term +120°C)
Special grades possible down to -50°C
