The right method to put an oil seal in a housing

Click For Summary
SUMMARY

The discussion centers on the proper method for installing an oil seal in a housing. It is established that applying grease between the housing and the oil seal can facilitate installation but poses a risk of the seal sliding out during or after assembly. Participants emphasize the dual nature of sealants, which act as lubricants during assembly but harden to provide sealing and retention. The consensus highlights the importance of balancing ease of replacement with the integrity of the seal under pressure.

PREREQUISITES
  • Understanding of oil seal installation techniques
  • Knowledge of sealant properties and applications
  • Familiarity with assembly lubricants and their effects

  • Study best practices for oil seal installation in various applications
  • Explore alternative methods for ensuring seal retention under pressure
USEFUL FOR

Mechanical engineers, automotive technicians, and anyone involved in the assembly or maintenance of machinery requiring oil seals.

i have a question, when i put a oil seal in a housing, should i put grease between the housing and the oil seal? because that is more easy to out in.

Can explain the theory to me please?

If you use grease the surface of the oil seal it will be able to slide out again during or after assembly.

Many sealants such as those used on gaskets and screw threads are lubricants during assembly, then they set to become both a seal and a retaining "glue".
 
It's a double edged sword. Under pressure, the seal material is more likely to migrate. Ease of seal replacement is a noble idea, but, easy access to seal surfaces is not necessarily a design priority.
