APPLICATIONS

  • Motor shafts 
  • Gear and dri­ve unit shafts 
  • Fan shafts 
  • Clam­ping tools
  • App­li­ca­ti­ons at high speed and low pres­su­re

CHARACTERISTICS

  • Pres­su­re-activa­ted seal ener­gi­za­ti­on
  • The inte­gra­ted or tur­ned out wedge pre­vents the sealing lip tur­ning insi­de out 
  • Very long seal life due to high abra­si­on resis­tan­ce 
  • Mate­ri­al only gene­ra­tes low fric­tio­n­al force
  • Sealing lip does not stick to the mating sur­face even after pro­lon­ged shut­down

TEMPERATURE RANGE

From ‑60 to +200 °C (tem­pora­ri­ly +260 °C)

but depen­dent on the mate­ri­al of the sealing lip and the O‑ring of the secon­da­ry seal in each case.

MATERIALS

IDG sealing lip mate­ri­al

  • 36B
  • 32B (oil hydrau­lics, pneu­ma­tics)
  • 82B (oil hydrau­lics, water hydrau­lics)
  • 40A (pneu­ma­tics)

Mate­ri­als Casing/clamping ring mate­ri­al

  • IDG mate­ri­al M41 (stain­less steel, mate­ri­al No. 1.4301)

O‑ring elas­to­mer (secon­da­ry seal)

  • NBR
  • FKM (hig­her chemical/temperature resis­tan­ce)

PV limits

This dia­gram gives PV limits which should be con­si­de­red as recom­men­da­ti­ons.

Prac­ti­cal preli­mi­na­ry tests are necessa­ry near the limit cur­ves and also for tem­pe­ra­tures and fluids dif­fe­rent from the ones used here.

Flu­id: Hydrau­lic oils, hydrau­lic fluids HFA and HFB
Tem­pe­ra­tu­re: 80 °C max.
Shaft seal mate­ri­al: 82B
Moti­on: Rota­ry
