GRN 130x160x13 NBR SC/BA - Single Lip Radial Shaft Oil Seal

Product Description

GRN 130x160x13 NBR A/BA is a single lip radial shaft oil seal (Simmerring) with an inner diameter of 130 mm, an outer diameter of 160 mm and an axial width of 13 mm. Manufactured from nitrile butadiene rubber (NBR), it features an A/BA sealing profile, typically incorporating a primary sealing lip, a garter spring and a rubber-covered outer diameter.

The GRN 130x160x13 oil seal is designed to reduce oil and grease leakage where a rotating shaft passes through a stationary housing. Its primary function is to retain lubricants inside mechanical assemblies and help prevent lubrication loss.

The A/BA profile is a single lip construction, without the additional dust exclusion lip commonly found in AO/TC double lip oil seals. It is suitable for appropriately designed applications where lubricant retention is the primary requirement and additional protection against external contamination is provided separately or is not required to the same extent.

With a nominal inner diameter of 130 mm, this seal may be used in appropriately designed industrial gearboxes, gear reducers, drive systems and machinery incorporating large-diameter rotating shafts.

Technical Specifications - GRN 130x160x13 NBR A/BA

Technical note: The A/BA designation describes a typical single lip radial shaft seal construction. Exact material specifications, sealing lip geometry and permissible operating limits for this GRN product should be confirmed in the manufacturer's technical documentation.

GRN 130x160x13 Oil Seal Dimensions

The designation 130x160x13 mm indicates a seal intended for a shaft with a nominal diameter of 130 mm, a housing bore with a nominal diameter of 160 mm and an installation space accommodating a width of 13 mm.

When selecting a replacement, shaft and housing tolerances, shaft surface finish and the construction of the original sealing component must also be verified.

What Does GRN 130x160x13 NBR A/BA 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.

130x160x13 - Nominal Dimensions

• 130 mm - inner diameter of the oil seal.

• 160 mm - outer diameter of the oil seal.

• 13 mm - axial seal width.

NBR - Nitrile Butadiene Rubber

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

A - Single Lip Sealing Profile

The designation A is used for radial shaft seal constructions incorporating a single primary sealing lip.

BA - Rubber-Covered Outer Diameter

BA is commonly used to identify a single lip radial shaft seal with a rubber-covered outer diameter and a spring-loaded primary sealing lip.

The A and BA designations may describe similar constructions, although their exact meanings depend on the manufacturer's designation system.

Construction of the GRN A/BA Single Lip Oil Seal

Primary Sealing Lip

The main working component is the sealing lip operating in contact with the rotating shaft surface.

Its function is to reduce oil or grease leakage from the mechanical assembly.

Garter Spring

In a typical A/BA construction, the primary sealing lip is supported by a garter spring.

The spring helps maintain contact between the sealing lip and the shaft during operation.

Internal Metal Reinforcement

Typical BA oil seals incorporate an internal metal reinforcing element that helps maintain the geometry of the seal body and stability within the housing.

Rubber-Covered Outer Diameter

The elastomer-covered outer surface helps create a static sealing interface between the seal body and the housing bore.

No Additional Dust Exclusion Lip

The A/BA profile is a single lip design and does not incorporate the additional dust exclusion lip typical of AO/TC constructions.

For applications involving significant dust exposure, the need for additional contamination protection should be evaluated.

NBR Material - Properties and Resistance

Resistance to Mineral Oils

NBR is widely used in sealing applications involving many mineral oils and industrial lubricating greases.

Flexibility and Mechanical Properties

The elastomer provides flexibility suitable for sealing lip operation against a rotating shaft when lubrication and operating conditions are appropriate.

Operating Temperature Range

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

This is not a confirmed operating temperature specification for the particular GRN 130x160x13 oil seal.

Actual permissible temperatures depend on the elastomer compound, operating medium, shaft speed and application conditions.

Chemical Limitations

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

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

A/BA vs AO/TC Oil Seals - Comparison

The choice between A/BA and AO/TC should depend on equipment design and operating conditions.

Identical nominal dimensions alone do not guarantee interchangeability.

Main Features of GRN 130x160x13 NBR A/BA

• Single lip A/BA construction.

• NBR elastomer material.

• Primary sealing lip.

• Garter spring typical of A/BA construction.

• Typically rubber-covered outer diameter.

• Typically internal metal reinforcement.

• Designed for rotating shaft sealing.

• Intended to reduce oil and grease leakage.

Typical Applications of GRN 130x160x13 Oil Seals

Industrial Gearboxes

Large-diameter radial shaft oil seals are used in gearboxes incorporating shafts that require oil retention.

Gear Reducers and Drive Systems

Single lip seals may be used to retain lubricants within appropriately designed power transmission assemblies.

Production Machinery

Radial shaft seals are commonly incorporated into rotating mechanical assemblies in industrial machinery.

Mechanical Equipment

A/BA seals may be suitable for shaft assemblies where the primary requirement is to reduce lubricant leakage.

Bearing Housings

In selected machinery designs, radial shaft seals operate alongside bearing housings to reduce oil or grease loss.

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

How to Select the Correct GRN 130x160x13 Oil Seal

Before purchasing, verify:

1. Shaft diameter - 130 mm.

2. Housing bore diameter - 160 mm.

3. Axial width - 13 mm.

4. Single lip A/BA profile.

5. NBR elastomer material.

6. Type of oil or grease.

7. Operating temperature.

8. Shaft rotational and surface speed.

9. Dust and contamination exposure.

10. Shaft surface condition and roughness.

11. Pressure and equipment design 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 130x160x13 mm alone does not guarantee oil seal interchangeability.

GRN 130x160x13 A/BA Replacement and Interchangeability

When selecting a replacement, confirm:

• Inner diameter of 130 mm.

• Outer diameter of 160 mm.

• Width of 13 mm.

• Single lip sealing profile.

• Elastomer material.

• Outer surface construction.

• Presence and type of garter spring.

• Operating conditions.

A double lip oil seal with identical dimensions may not always replace an A/BA single lip version without additional verification.

Installation Instructions - GRN 130x160x13 Oil Seal

Shaft Preparation

Before installation, inspect the shaft surface for corrosion, scratches, 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 applying direct impact to the sealing lip or garter spring.

Installation Orientation

In typical applications, the spring-loaded sealing lip should face the lubricant being retained.

However, the equipment manufacturer's installation instructions must take precedence.

Lubrication

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

Dry running may cause overheating and premature wear.

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 swelling or degradation.

Exceeding Operating Limits

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