APPLICATIONS

  • Uni­ver­sal use for line­ar, heli­cal, rota­ry and oscil­la­ting moti­on
  • At mode­ra­te rota­ry speed it can also be used as a shaft seal 
  • Par­ti­cu­lar­ly sui­ta­ble for non-stan­dard hydrau­lic and pneu­ma­tic cylin­ders and app­li­ca­ti­ons in gene­ral mecha­ni­cal and plant engi­nee­ring

Elas­to­me­ric wipers/scrapers are used in com­bi­na­ti­on with the MANOY® sli­ding ring, the MANOY® U‑Cup or other rod seals. Typi­cal app­li­ca­ti­ons for the­se com­ple­te solu­ti­ons are:

  • Pis­ton rods
  • Plun­gers
  • Tap­pets
  • Val­ve spind­les
  • Gui­de rods

CHARACTERISTICS

  • Good wiping/scraping effect 
  • Wide pres­su­re and tem­pe­ra­tu­re spec­trum
  • Full dry run­ning pos­si­ble – low bre­a­ka­way tor­que, no stick-slip effect at craw­ling speed
  • Adap­tati­on to housing spe­ci­fi­ca­ti­ons with non-stan­dard dimen­si­ons is nor­mal­ly pos­si­ble
  • With rota­ry moti­on (shaft seal) com­pen­sa­tes for radi­al run­out and tilt (varia­ble spring design)
  • For rota­ry, oscil­la­ting and slow advan­ce heli­cal moti­on

Type 916 is not sui­ta­ble for pres­su­re app­li­ca­ti­on.

Elas­to­me­ric wiper/scraper:

  • Pre­vents the ingress of dirt, mois­tu­re or loo­se par­ti­cles kee­ping them away from the seal sur­faces and the inner sys­tem
  • For line­ar and rapid advan­ce heli­cal moti­on
  • Type AD pro­vi­des out­si­de exclu­si­on and retains the resi­du­al lub­ri­cant film on the insi­de

TEMPERATURE RANGE

Type 916:

From ‑54 to +200 °C (tem­pora­ri­ly 260 °C)

but depen­dent on the wiper/scraper and O‑ring mate­ri­al in each case.


O‑ring elas­to­mer:

NBR-90 / nitri­le buta­di­e­ne -25 to +100 °C

FKM-85 / fluo­ro­car­bon -20 to +200 °C


on request:

AU-90 / poly­ure­tha­ne -30 to +100 °C

Wiper/scraper cross­sec­tions in alter­na­ti­ve ver­si­ons

The stan­dard ver­si­on is uni­ver­sal­ly usable, but in spe­cial cases the light ver­si­on can offer addi­tio­nal advan­ta­ges.
The light ver­si­on is sui­ta­ble for tight instal­la­ti­on con­di­ti­ons and is also easier to fit in non-split groo­ves. This ver­si­on redu­ces the fric­tion. The low com­pres­si­on reser­ve with a nega­ti­ve effect on lar­ge tole­ran­ces must be con­si­de­red.
