Classification of shaft seals

Radial oil-seal with a pressing spring, working at pressure falls 0,05-0,15 MPa is the most widespread type of sealings of shafts thereof to relative simplicity and low cost, small sizes, sufficient sealing ability and an opportunity of maintenance in contact with many mediums. These oil-seal's properties are defined by a successful embodiment in a small-sized design of advantages of elastomeric sealing and  spring which has stable in all a temperature range parameters and is not subject to a strain ageing.

The basic designs of oil-seals we offer are:

 

Rubber covered case:

Opened case:

 

 

BA

B1

 
 

 

Design with a dust-lip:

Design without a dust-lip:

 

 

SL

D

 

The following designations are used:

KL - the calibrated case
RD - clockwise rotation
RS - counter clockwise
SF - special design
X7 - flutes on outer diameter
 

Application of Oil seals

  •         Used in hydraulic rams and mixers, valves, brake devices, clean rooms, conveyers and test equipment

  •         Used in constantly moving equipment like cylinders, rotating or reciprocating shafts and cylinders

  •         Bearing isolators are used for pumps, motors and gear boxes

  •         Used in vehicles, automotives, power generation, industrial engines and transmissions

  •         Water pumps

  •         Crankshaft front

  •         Camshaft

  •         Valve stem

  •         Steering

  •         Crankshaft rear

  •         Gear box front

  •         Transmission front

  •         Selector shaft

  •         Speedometer

  •         Gear box rear / transmission rear

  •         Propeller shaft

  •         Pinion / differential

  •         Rear hub inner/ rear wheel inner / rear axle inner
