FEATURES |
|
General purpose, non pressure fluid & severe grease sealing. ( max. pressure 0.3 kg/cm² ) |
Lip : Having spring fitted seal lip. Most popular seal type. |
|
General purpose, non pressure fluid & severe grease sealing with light exclusion of foreign materials. ( max. pressure 0.3 kg/cm² ) |
Lip : A combination of spring fitted seal lip and dust lip. If grease is applied between the sealing lip and dust lip, it can be used even lubeless when temporary condition occurs. |
|
Seals for construction machinery & vehicles. Also for heavy dust condition and preventing vacuum between lips in case of high speed shaft. |
Lip : A combination of spring fitted seal lip and special synthetic fabric dust lip. With this special mat. Dust lip, it is able to provide ventilation dust proof & low abrasive characteristics. |
|
Economical design for grease & dust sealing no suitable for viscous fluid. |
Lip : A spring-less seal lip. Can be used with S type or T type seal. |
|
Economical design for grease retention or sealing viscous fluid with light duty exclusion of dust or foreign materials. |
Lip : A combination of spring-less seal lip and dust lip. If grease is applied between the seal lip & dust lip, it can be used even lubeless when temporary conditions occurs. |
|
Medium pressure seal for oil and water application. ( max. pressure 3 kg/cm² ). Not recommended for shaft size over Ø 63mm. |
Lip : A combination of spring fitted seal lip & dust lip. The seal lip is designed to withstand pressure from deformation when pressure increased. |
|
High pressure seal for oil & water application. ( max. pressure 10 kg/cm² ) |
Lip : A combination of spring fitted seal lip & dust lip with a reinforced metal casing to reduce deformation of the seal lip due to increase pressure. |
|
For reciprocal motion. Hydraulic or shock absorber seal. |
Lip : A combination of spring fitted seal lip and dust lip. The seal lip is designed to prevent lip deformation due to reciprocal motion. |
|
Seals for engine, torque converter pump & washing machine. ( max. pressure 1 kg/cm² ). Suitable for high temp, high speed shaft, low torque and insufficient lubrication condition. |
Lip : A combination of spring fitted seal & dust lip. The seal lip is coated with polytetraflouride ethylene resin ( NOK rarefron® ) |
