Simrit 165x190x17 COMBI NBR Rotary Shaft Oil Seal

Simrit 165x190x17 COMBI NBR is a heavy duty rotary shaft oil seal designed for front axle hub assemblies and rotating shafts used in agricultural and industrial machinery. The COMBI sealing design provides reliable lubricant retention while protecting the drivetrain from dust, moisture and abrasive contaminants.

A COMBI oil seal is a specialized radial shaft sealing solution that combines the function of a standard oil seal with additional protection against environmental contamination. The Simrit 165x190x17 COMBI seal is engineered for applications where rotating shafts operate in harsh working conditions such as soil, mud, water and mechanical debris.

This type of sealing ring is commonly installed in front axle hub systems where durable sealing and long service life are required.

Construction and COMBI sealing design

COMBI type rotary shaft seals are developed for demanding machinery applications where contamination protection is as important as oil retention.

The Simrit COMBI seal includes several structural elements:

reinforced metal outer casing for stable housing installation
primary NBR sealing lip designed to retain oil and grease
secondary dust protection lip preventing contamination ingress
optimized lip geometry for rotating shaft contact

This configuration creates a protective barrier between the lubricated internal components and the external environment. As a result the seal protects shafts, bearings and hub assemblies from premature wear.

Compared to standard simering oil seals, COMBI seals provide improved durability in machines operating in dusty or wet environments.

Technical specifications

Product type: rotary shaft oil seal COMBI
Brand: Simrit
Product number: 12001925

Inner diameter: 165 mm
Outer diameter: 190 mm
Width: 17 mm

Sealing material: NBR nitrile rubber

Application: front axle hub shaft sealing

NBR elastomer offers high resistance to:

mineral oils
lubricating greases
mechanical wear
moderate operating temperatures

These properties make NBR one of the most commonly used materials for industrial rotary shaft sealing systems.

Application in agricultural and industrial machinery

Cassette and COMBI oil seals are widely used in machines where rotating shafts must operate reliably in contaminated environments.

Typical applications include:

front axle hub systems
agricultural tractors
construction machinery drivetrains
industrial rotating shaft assemblies
heavy duty mechanical equipment

In these systems the oil seal maintains lubrication inside the hub assembly and prevents contamination that could damage bearings and drivetrain components.

Operational advantages of Simrit COMBI seals

Using a COMBI oil seal improves reliability and durability of rotating mechanical systems.

Key operational advantages include:

reliable oil retention in axle hub assemblies
protection against dust, mud and moisture
extended bearing and drivetrain service life
precise dimensional fit for shaft sealing applications
stable performance in agricultural and industrial environments

Because of these benefits COMBI seals are frequently used in maintenance, repair and replacement of sealing systems in heavy duty machinery.

FAQ - technical questions about Simrit 165x190x17 COMBI

What is a COMBI oil seal?

A COMBI oil seal is a rotary shaft seal that combines a standard oil sealing lip with additional protection against contamination such as dust, mud and debris.

Where is the Simrit 165x190x17 COMBI seal used?

It is mainly used in front axle hub systems and rotating shaft assemblies in agricultural and industrial machinery.

Is NBR suitable for oil sealing applications?

Yes. NBR nitrile rubber offers excellent resistance to oils and greases and is widely used in rotary shaft oil seals.

Can the 165x190x17 COMBI seal be used in different machines?

Yes, provided that the shaft diameter, housing diameter and width correspond to the dimensions 165x190x17 and the application requires a COMBI type seal.

What is the advantage of COMBI seals compared to standard oil seals?

COMBI seals offer improved protection against contamination and provide longer service life in harsh operating environments.
