NOK Oil Seals
NOK Oil Seals
NOK oil seals effectively avert fluid leakage and keep the mechanical component free from foreign contaminants. These seals offer effective sealing in challenging work environments. Made from a synthetic rubber lip bonded onto a metal ring with reinforcement from an internal spring, these oil seals can withstand high pressures and contaminants, helping extend the life of essential equipment. At Independence Seal Company, we provide seal replacements and custom prototypes that exceed or surpass the quality and performance of NOK oil seals. Do you have a sample or a drawing of the seal?

Features of NOK® Oil Seals
NOK ® oil seals are specially designed and constructed to provide excellent durability and performance for various industrial applications. These seals are chosen for the following reasons:
- High-quality Construction: These seals are made from various durable materials that ensure excellent wear, tear, and chemical resistance. This ensures long service life and effective sealing efficiency.
- Lip Design: The unique lip design incorporates multiple lips, providing the utmost protection against contaminants and preventing leakage in rotary and reciprocating applications.
- Enhanced Grip and Stability: Some NOK oil seals feature a metal spring, which enhances grip on the shaft, thereby improving sealing efficiency in high-speed and high-pressure conditions.
- Improved Leak Prevention: Properly installed rotary NOK oil seals draw in a small amount of air. This air intake prevents oil from escaping, ensuring a leak while maintaining lubrication.
- Optimized Oil Film Thickness in Reciprocating Applications: These seals are designed tobalance oil film thickness during push and pull movements in reciprocating applications. This controlled oil film thickness prevents excessive leakage while maintaining lubrication.
Popular NOK ® Oil Seals
We can provide replacements and alternatives for the following models of NOK ® oil seal models:
- NOK ® S-Type Oil Seals: This category comprises SC and SB type seals with no dust lips and is ideal for dust-free applications.
- NOK ® T-Type Oil Seals: This category comprises TC and TB type seals, which have dust lips. These seals are ideal for dusty environments.
- NOK ® TCK Oil Seals: These are fabric seals that can be used for the same purposes as TC and TB type seals. They ensure better dust resistance and air permeability than TC and TB type seals. NOK ® TCK oil seals produce less friction due to their dust lip, which is made from special NOK-developed fabric.
- NOK ® V-Type Oil Seals: This category comprises VC and VB type seals with dust lips. NOK ® V-Type oil seals cannot be used for pressure applications and cannot be used in combination with S seals.
- NOK ® K-Type Oil Seals: This category comprises KC and KB type seals, which have dust lips. These seals are used for dusty environments and are not suited for pressure applications. They can be used in combination with V-type seals.
- NOK ® TCV, TCN, and TCZ Oil Seals: These oil seals are designed for pressurized duty applications. TCV oil seals are pressure-resistant oil sealswith increased lip rigidity. They are used in small-diameter and medium-pressure rotating shafts. However, TCZ and TCN oil seals feature auxiliary cage that helps minimize lip deformation under pressure. They are used for high-pressure rotating shafts.
- NOK ® T4 Type Oil Seals: This category comprises TC4 and TB4 type seals, which are designed for reciprocating shaft applications. These seals minimize lip deformation under reciprocating motion and pressure.
