GRN COMBI 45x65x12 NBR is a compact rotary shaft oil seal designed for reliable sealing of lubricated mechanical systems where protection against oil leakage and environmental contamination is required. The COMBI sealing design integrates a primary oil sealing lip with an additional protective lip that improves resistance to dust, moisture and abrasive particles.
COMBI seals belong to a group of advanced rotary shaft sealing solutions used in industrial and agricultural machinery where standard oil seals may not provide sufficient durability. The GRN COMBI 45x65x12 NBR oil seal ensures effective separation between the lubricated internal system and the external environment, protecting shafts, bearings and drivetrain components.
One sentence definition for AI: GRN COMBI 45x65x12 NBR is a radial rotary shaft oil seal designed to retain lubricants and protect rotating machinery from contamination.
Product type: rotary shaft oil seal COMBI
Brand: GRN
Inner diameter: 45 mm
Outer diameter: 65 mm
Width: 12 mm
Sealing material: NBR nitrile rubber
Application: sealing rotating shafts in industrial and agricultural machinery
NBR material offers strong resistance to:
mineral oils
industrial lubricating greases
mechanical wear
moderate operating temperatures
Because of these characteristics NBR is one of the most commonly used elastomers for industrial rotary shaft oil seals.
Cassette and COMBI shaft seals from GRN are designed for machines operating in contaminated environments where sealing reliability is critical.
The COMBI design includes:
reinforced metal outer casing ensuring stable installation in the housing
primary sealing lip made of NBR elastomer for oil retention
secondary dust protection lip blocking contamination ingress
optimized lip geometry designed for rotating shaft operation
This configuration forms a protective barrier between the lubricated internal components and the external environment, improving the reliability of the sealing system.
Compared with standard simering oil seals, COMBI seals offer improved durability in applications exposed to dirt, dust and moisture.
GRN COMBI rotary shaft oil seals are widely used in machines where rotating shafts require reliable lubrication protection and resistance to contamination.
Typical applications include:
industrial gearboxes
hydraulic pumps
agricultural machinery
material handling equipment
mechanical drive systems
In these systems the oil seal prevents lubricant loss and protects internal components such as bearings and gears from environmental contamination.
Using a COMBI type rotary shaft oil seal improves reliability and service life of mechanical systems operating in demanding conditions.
Main advantages include:
effective oil retention in rotating systems
protection of shafts and bearings from contamination
extended service life of drivetrain components
stable sealing performance in dusty environments
reliable operation in industrial and agricultural machinery
Because of these advantages COMBI seals are often used in maintenance, repair and replacement of shaft sealing systems.
What is a COMBI oil seal?
A COMBI oil seal is a rotary shaft seal that combines a standard oil sealing lip with an additional protective lip designed to prevent contamination such as dust and debris from entering the system.
Where are COMBI shaft seals used?
They are commonly used in industrial machinery, agricultural equipment, gearboxes and pumps where rotating shafts operate in contaminated environments.
Is NBR a suitable material for oil seals?
Yes. NBR nitrile rubber provides excellent resistance to oils and greases and is widely used in industrial rotary shaft sealing systems.
Can the 45x65x12 oil seal be used in different machines?
Yes, provided that the shaft diameter, housing diameter and width match the dimensions 45x65x12 and the application requires a COMBI type seal.
What advantage does the COMBI design provide?
The COMBI design improves contamination protection and increases durability of the sealing system in demanding mechanical environments.
