NOK Type & Design Applications    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 condition occurs. 
NOK Type & Design Applications Features
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 increased 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®) 
Medium pressure seal for liquid chemical, solvent and fuel oil. To substitute for normal rubber bonded seal, which is not suitable for these application (max. pressure 3 kg/cm²)  Lip: A combination of spring fitted seal lip. The seal lip mat. is made of polytetraflouride ethylene resin. (NOK rarefron®) 
NOK Type & Design Applications Features
Splash seal for liquid chemical & fuel oil. Dust seal for high temperature without lubrication (max. pressure 1.0 kg/cm²)  Lip: Spring-less seal lip with one main sealing lip (VAJ) or two main lips in the same direction (KA31). The seal lip mat. is made of polytetraflouride ethylene resin. 
This seal is designed for sealing two different sealing fluids. (max. pressure 0.3 kg/cm²). This design can be substitute with 2 SB/SC type by installing back to back.  Lip: A combination of two springs fitted seal lip facing in the opposite direction. 
Outer sealing the shaft does not revolve but the housing rotate (max. pressure 0.3 kg/cm²)  Lip: The spring is fitted on the outer seal lip. Require good housing bore inner surface finish. 
This is attached to shaft and slides the seal lip on the terminal wall of the fixed end preventing leakage of grease an infiltration of water, dust and foreign object.  Lip: It is a single lip seal of rubber, and cross-section of a V shape. 
Used mainly as a light duty dust seal, grease seal for roller bearing plumber block.  Lip: The cross-section of this seal is almost like a Z shape, comprise of a simple rubber substance.
ZF - single seal lip.
ZT - seal lip with dust lip. 
NOK Type & Design Applications Features
Mainly used for the roll neck of the rolling machine. It prevents entry of cooling water, oil and scale. (size not listed in this catalogue)  Lip: A combination of spring -less outer seal lip and dust lip, both lips facing the same direction. 
  This seal is mainly used for automotive engine, differential gears & transmission.  Lip: Having spiral line all over the seal lip periphery. These spiral lines push back fluid likely to leak through the sealing portion due to pumping action. A clockwise or anti-clockwise spiral is available.
