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

CHARACTERISTICS

  • Good wiping/scraping effect 
  • Wide flu­id 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.

TEMPERATURE RANGE

Type 916:

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

Depend­ent on the wiper/scraper and O-ring mater­i­al in each case.

Types 956, 966 and 988:

From -200 to +200 °C (tem­por­ar­ily to 260 °C)

Depend­ent on the wiper/scraper and spring mater­i­al in each case.

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.
