GRN® 130x150x10 NBR AO/TC - Double Lip Radial Shaft Oil Seal

Product Description

GRN® 130x150x10 NBR AO/TC is a double lip radial shaft oil seal (Simmerring) with an inner diameter of 130 mm, an outer diameter of 150 mm and an axial width of 10 mm. Manufactured from nitrile butadiene rubber (NBR), it features an AO/TC sealing profile with a primary sealing lip and an additional dust exclusion lip. The seal is designed to reduce oil and grease leakage while limiting contamination ingress into rotating mechanical assemblies.

The GRN® 130x150x10 NBR AO/TC oil seal is intended for a shaft with a nominal diameter of 130 mm and a housing bore with a nominal diameter of 150 mm.

Its axial width is 10 mm, while its nominal radial cross-section height is also 10 mm. These dimensions are particularly relevant in mechanical assemblies with limited installation space.

The double lip construction helps retain lubricants while providing an additional barrier against dust and fine contaminants.

The TC profile is commonly associated with a double lip radial shaft oil seal featuring a rubber-covered outer diameter, internal metal reinforcement and a spring-loaded primary sealing lip. However, the exact construction of this specific GRN® product should be confirmed in the manufacturer's technical documentation.

Technical Specifications - GRN® 130x150x10 NBR AO/TC

Technical note: AO and TC designations describe similar double lip constructions but are not always fully equivalent between manufacturers. Before selecting an alternative seal, its construction details and operating conditions must be verified.

GRN® 130x150x10 Oil Seal Dimensions

The designation 130x150x10 mm identifies the essential installation dimensions.

• Shaft diameter: 130 mm.

• Housing bore diameter: 150 mm.

• Oil seal width: 10 mm.

Compared with the 130x150x15 mm version, the 130x150x10 mm oil seal has an axial width that is 5 mm smaller.

The 130x150x10 and 130x150x15 versions are not automatically interchangeable, because they have different widths and may require different installation arrangements.

What Does GRN® 130x150x10 NBR AO/TC Mean?

GRN® - Industrial Sealing Components Brand

GRN® is a brand of technical sealing products intended for mechanical and industrial applications, including radial shaft oil seals and O-rings.

130x150x10 - Nominal Dimensions

• 130 mm - inner diameter.

• 150 mm - outer diameter.

• 10 mm - axial width.

NBR - Nitrile Butadiene Rubber

NBR is a synthetic elastomer commonly used in seals exposed to many mineral oils, lubricating greases and selected petroleum-based substances.

AO - Double Lip Sealing Profile

AO identifies a construction with a primary sealing lip and an additional dust exclusion lip.

TC - Double Lip Radial Shaft Oil Seal

TC is a widely used designation for a double lip radial shaft oil seal, typically featuring a rubber-covered outer diameter and a spring-loaded primary sealing lip.

AO and TC may describe similar sealing arrangements, but complete equivalence should not be assumed without verification.

Construction of the GRN® AO/TC Oil Seal

Primary Sealing Lip

The primary sealing lip operates against the rotating shaft surface and is responsible for reducing lubricant leakage.

Correct operation depends on sealing lip geometry, shaft condition, lubrication and operating conditions.

Additional Dust Exclusion Lip

The secondary lip provides an additional barrier against dust and fine contaminants entering the primary sealing area.

This does not guarantee complete protection against pressurized water or extremely contaminated operating environments.

Garter Spring

In typical TC constructions, the primary sealing lip is supported by a garter spring that helps maintain appropriate contact with the shaft surface.

The exact configuration of this GRN® oil seal requires confirmation.

Internal Metal Reinforcement

Typical TC designs incorporate an internal metal reinforcing element that supports the seal body and helps maintain its geometry.

Rubber-Covered Outer Diameter

In a typical TC profile, the outer surface is covered with elastomer to help provide static sealing between the seal body and housing bore.

NBR Material - Properties and Resistance

Resistance to Mineral Oils

NBR is widely used in seals operating with many mineral oils and industrial lubricating greases.

Flexibility and Mechanical Properties

Nitrile rubber provides the flexibility required for a sealing lip to operate against a rotating shaft surface.

Operating Temperature Range

Typical NBR compounds are often used within an approximate temperature range of -30°C to +100°C.

This is not a verified temperature range for the specific GRN® 130x150x10 product. Actual permissible values depend on the elastomer compound, lubricant, shaft speed and operating conditions.

Chemical Limitations

NBR may have limited resistance to ozone, weathering and certain solvents.

For applications requiring higher temperature resistance or specific chemical compatibility, an appropriately selected FPM/FKM oil seal may be considered.

AO/TC vs A/BA - Construction Comparison

The AO/TC profile may be advantageous in applications where limiting contamination ingress is important in addition to retaining oil or grease.

Typical Applications of GRN® 130x150x10 Oil Seals

Industrial Gearboxes

Radial shaft oil seals are used in gearboxes requiring oil retention within the housing.

Gear Reducers and Drive Systems

Double lip oil seals can help reduce lubricant loss and limit contamination ingress into mechanical assemblies.

Production Machinery

This type of seal may be used in appropriately designed rotating assemblies of industrial production equipment.

Mechanical Equipment

The AO/TC profile may be used in mechanisms requiring additional protection against dust.

Bearing Housings

In selected mechanical constructions, radial shaft oil seals operate alongside bearing housings to reduce oil or grease leakage.

These are general application examples and do not establish verified compatibility with specific OEM equipment.

How to Select the Correct GRN® 130x150x10 NBR AO/TC Oil Seal

Before purchasing, verify:

1. Shaft diameter - 130 mm.

2. Housing bore diameter - 150 mm.

3. Axial width - 10 mm.

4. Double lip AO/TC profile.

5. NBR elastomer material.

6. Type of oil or grease.

7. Operating temperature.

8. Shaft rotational and surface speed.

9. Environmental dust exposure.

10. Shaft surface condition and roughness.

11. Pressure and construction requirements.

For a shaft diameter of 130 mm, surface speed is particularly important because it depends on both shaft diameter and rotational speed.

Matching the dimensions 130x150x10 mm does not guarantee complete interchangeability between oil seals.

GRN® 130x150x10 AO/TC Replacement and Interchangeability

When selecting a replacement, confirm:

• Inner diameter of 130 mm.

• Outer diameter of 150 mm.

• Width of 10 mm.

• Double lip construction.

• Elastomer material.

• Outer surface design.

• Presence of a garter spring.

• Operating conditions.

A single lip A/BA oil seal with identical dimensions may not always be a suitable replacement for the AO/TC version.

Installation Instructions - GRN® 130x150x10 Oil Seal

Shaft Preparation

Inspect the shaft surface for scratches, corrosion, burrs and wear.

Housing Preparation

The housing bore should be clean, undamaged and manufactured to the required tolerances.

Installing the Seal

Press the oil seal evenly into the housing using an appropriate installation tool.

Avoid direct impact on the sealing lips or deformation of the seal body.

Installation Orientation

In typical applications, the primary sealing lip should face the oil or grease being retained, while the dust exclusion lip faces the external environment.

However, the equipment manufacturer's installation instructions must always be followed.

Lubrication

Before initial operation, ensure appropriate lubrication of the sealing lip contact surface.

For double lip constructions, the lubrication requirements of the space between the lips should also be considered.

Common Causes of Oil Seal Failure

Incorrect Installation

Misalignment of the seal body may cause leakage.

Damaged Shaft Surface

Scratches and surface irregularities can accelerate sealing lip wear.

Inadequate Lubrication

Insufficient lubrication increases friction and operating temperature.

Incorrect Material Selection

Exposure to an operating medium incompatible with NBR may cause elastomer degradation.

Exceeding Operating Limits

Excessive temperature, speed or pressure may reduce sealing performance and service life.
