Oil seals
Purpose: Rotary shaft seals
Working medium: water, mineral oil, diesel fuel.
Operating temperature: -60 to +170 ° C depending on the group of rubber.
Operating pressure: up to 0,07 MPa (0.5 kgf/cm2).
Shaft Speed: Up to 20 m / s.
Oil seals are two types:
• Single-breasted
• Double-breasted
Standard types in accordance with DIN 3760
SC Shaft seal with rubber covered O.D.(Ref. DIN 3760 “A” type)
TC Shaft seal as above but an auxiliary lip provides protection against dirts.(Ref. DIN 3760 “AS” type)
Special types:
*SB*SB2*SBR*TB2*TB*TBR*TA2*SCB*TBC*SBCW*TBCW*DC*TCV*TCP*TCHP*HSCL
