Technical Data

Double Lip Rotary Shaft O Ring Seals Akoken PTFE for Screw Air Compressor Industry Seal

This shaft oil seal comprises of a stainless steel casing and PTFE shaft seal lip. There are many types of the seal lip: single lip,double lips and three  lips or with no lip,etc.

 Properties of products
 
1, we use lip material with lowest solid friction coefficient (wet friction coefficient 0.02~0.04 ), and these oil seals with excellent self-lubricate and abrasive resistance, will not rub the shaft.
 
2, t can be interchanged with rubber oil seals, and sealing property more reliable.
 
3, main used for internal combustion engines, screw compressors, axles, gearboxes and other dynamic rotating seal
 
4, excellent self-lubricate and abrasive resistance,is an ideal oil-free lubrication sealing material
 
5, extensive temperature range,can be long used between -180°C~+250°C
 
6, capacity in resisting the corrodent ,such as strong acid,alkali, oxidizer.,with the excellent chemical stability.

--Charastic of  oil seals

1.Main lip 
Our main lip is durable and elastic,have many types of oil drive-back thread,the sealing edge contats around the shaft surface tightly in order to provide excellent sealing performance,when oil seals working,it can be placed under various stresses, good performance to generate force to keep the sealing edge consistently in contact with the shaft under such stresses

2.Dust lip
The double lip oil seals have dust lip,which prevents the dust and contaminants from outside environment,our dust lip also can retain grease in the space between main lip and dust lip.

3.OD surface
We have virous types of OD surface,it help seals fitted tightly into the housing and prevents the oil leakage through fitting house,we can make the OD surface rubber or metal,or half rubber half metal,depending on your application.

4.Spring
We have springs with many tension of diffierent performance,and material can be carbon steel or stainless steel.The spring provide the tension between shaft and main lip to ensure tight contact and enhanced sealing performance. the spring also can prevents the deterioration of main lip that caused by corrosion,high temperature or others.

5.Metal case
We produce the metal case by ourself,we have ten punchers.The metal case provides rigidity on oil seal,helping it to fix on the housing securely.
