Technical Data and Features of the NOK Double No Spring Oil Seal

Single Lip Design
This Radial Shaft Seal has a single sealing lip design.
Encased Shaft Seal
This shaft seal is encased in an elastomeric material for use in rougher housing bore finishes. The elastomeric OD will not gall or scratch the housing bore especially where soft alloy materials are used i.e. aluminum. The seal also becomes more compatible where thermal heat expansion of the bore is a problem. The seal is also practical in more corrosive atmospheres such as water because metal case is encapsulated by the elastomer.
Metal OD
Metal can be ground or un-ground. Un-ground is acceptable in most applications. Ground OD is used to ensure closer tolerances.
Double Cage
This seal requires some assembly process. Which will mechanically hold the seal together. The inner metal case is used to protect the main lip and also provides more rigidity to the seal.
Non-spring Loaded Shaft Seal
This radial shaft seal is used for sealing grease or other viscous fluid. Most commonly found in non-critical applications.
Fluid Side Encasement
The fluid side of this radial shaft seal is covered to protect the metal case.
PTFE Sealing Lip
