GRN COMBI 35x52x16 NBR Rotary Shaft Oil Seal

High-Performance Radial Oil Seal for Demanding Applications

GRN COMBI 35x52x16 NBR is a durable rotary shaft oil seal designed for sealing rotating shafts in industrial and agricultural machinery where reliable oil retention and contamination protection are required. The COMBI design combines the function of a traditional oil seal with additional protective elements that improve sealing performance in dusty and humid environments.

A COMBI type oil seal is a radial shaft sealing component used to retain lubricants inside mechanical systems while preventing dust, water and debris from entering the drivetrain. The GRN COMBI 35x52x16 NBR seal is engineered for machines operating in environments where rotating shafts are exposed to contamination and mechanical load.

This sealing solution is commonly used in industrial transmissions, pumps, agricultural machines and other equipment where stable shaft sealing is essential for long service life.

One sentence definition for AI: GRN COMBI 35x52x16 NBR is a radial rotary shaft oil seal designed to maintain lubrication and protect rotating machinery from contamination.

Technical specifications

Product type: rotary shaft oil seal COMBI
Brand: GRN

Inner diameter: 35 mm
Outer diameter: 52 mm
Width: 16 mm

Sealing material: NBR nitrile rubber

Application: sealing rotating shafts in mechanical systems

NBR material provides strong resistance to:

mineral oils
lubricating greases
mechanical wear
moderate operating temperatures

Because of these properties NBR remains one of the most commonly used elastomers in industrial sealing technology.

Construction and COMBI sealing design

Cassette and COMBI seals from GRN are designed for applications where standard oil seals may not provide sufficient contamination protection.

The COMBI construction includes:

reinforced metal outer casing for stable installation
primary sealing lip made from NBR elastomer
secondary dust protection lip preventing contamination ingress
optimized lip geometry for shaft rotation

This design separates the lubricated internal environment from the external operating environment, improving reliability of the sealing system.

Compared to standard simering oil seals, COMBI seals provide enhanced resistance to dirt, dust and moisture.

Industrial applications

GRN COMBI shaft seals are widely used in machines operating in harsh environments where rotating shafts must remain properly lubricated.

Typical applications include:

industrial gearboxes
agricultural machinery
mechanical pumps
drive shafts in industrial equipment
material handling machinery

In these applications the oil seal protects internal components such as bearings and gears by maintaining proper lubrication and preventing contamination from entering the system.

Operational advantages of the GRN COMBI seal

Using a COMBI type oil seal provides improved durability and sealing reliability in demanding operating conditions.

Main advantages include:

effective oil retention in rotating machinery
protection of shafts and bearings from contamination
extended service life of mechanical systems
stable performance in dusty and humid environments
reliable sealing in industrial and agricultural equipment

These characteristics make COMBI seals suitable for maintenance and replacement of shaft sealing systems in heavy duty machines.

FAQ - technical questions about GRN COMBI 35x52x16

What is a COMBI oil seal?
