CORTECO 01029677 NBR B1 65x80x8 mm - Radial Shaft Oil Seal

CORTECO 01029677 - Product Characteristics

The CORTECO 01029677 radial shaft seal is designed for sealing rotating shafts in mechanical assemblies where lubricating oil or grease must be retained within a housing.

Its B1 construction incorporates a metal outer casing for secure installation in the housing bore and an elastomeric sealing element that contacts the rotating shaft.

The NBR sealing material offers resistance to many mineral-based oils, greases and industrial lubricants. Compatibility with specific fluids and operating conditions must be verified before installation.

The 65x80x8 mm dimensions identify the nominal shaft diameter, housing bore diameter and axial width of the seal.

Technical Specifications - CORTECO 01029677

What Does CORTECO 01029677 NBR B1 Mean?

The designation identifies the manufacturer, specific product reference, sealing material and construction profile.

• CORTECO - the manufacturer brand specializing in sealing technology and automotive and industrial sealing components.

• 01029677 - the manufacturer's product reference number.

• NBR - nitrile butadiene rubber, an elastomer commonly used in oil seals because of its compatibility with many mineral oils and greases.

• B1 - a radial shaft seal construction featuring a metal outer casing.

• 65x80x8 mm - the nominal shaft diameter, housing bore diameter and axial width.

The B1 profile should not automatically be considered interchangeable with BA, BASL, B1SL or other shaft seal profiles. Differences in casing design, sealing lip configuration and operating characteristics may affect compatibility.

Construction and Operating Principle

The CORTECO 01029677 oil seal forms a sealing interface between a rotating shaft and a stationary housing.

Its principal functional components include a metal outer casing and an NBR sealing lip.

The metal casing provides structural support and enables the seal to be fitted into the housing bore. The elastomeric lip forms the contact sealing interface with the shaft surface.

During operation, the sealing lip maintains contact with the rotating shaft to restrict lubricant leakage.

Effective sealing depends on correct installation, shaft surface condition, alignment, lubrication and compatibility between the elastomer and the operating medium.

The nominal width of 8 mm is important for correct positioning within the housing.

OEM Reference Numbers and Cross-References

The following reference numbers are associated with CORTECO 01029677:

These reference numbers support part identification for agricultural machinery and mechanical assemblies.

However, an OEM reference does not establish compatibility with every machine or transmission manufactured under the corresponding brand.

The original equipment part number and the technical documentation of the specific assembly should be checked before ordering.

Alternative Designations and Product References

The product may be identified using the following designation formats:

• CORTECO 01029677

• 01029677 CORTECO

• CORTECO 01029677 NBR B1

• CORTECO B1 65x80x8 mm

• B1 radial shaft oil seal 65x80x8 mm

• CORTECO Simmerring 65x80x8 NBR

Some aftermarket catalogues also associate references 01029677B and 82029677 with this product family. Their equivalence to CORTECO 01029677 should be confirmed against current manufacturer documentation before substitution.

CORTECO 01029677 Compared with Other 65x80x8 mm Oil Seals

Radial shaft seals with identical nominal dimensions may differ in construction, elastomer material, sealing lip arrangement and operating characteristics.

For example, B1, B1SL and other seal profiles may share the same dimensions but have different structural or sealing features.

These differences can affect installation requirements, sealing performance and suitability for particular operating conditions.

A seal with dimensions of 65x80x8 mm is therefore not automatically a direct replacement for CORTECO 01029677.

Applications of CORTECO 01029677

CORTECO 01029677 is associated with OEM reference numbers from ZF, CLAAS and FENDT.

Its radial shaft sealing construction is intended for mechanical assemblies in which a rotating shaft passes through a stationary housing and lubricant retention is required.

Typical functions of this seal type include limiting oil leakage and maintaining separation between the lubricated interior of a mechanical assembly and its external environment.

Compatibility with a specific agricultural machine, transmission or drive assembly must be established through the original equipment reference and technical documentation.

Selection and Interchangeability

Before selecting CORTECO 01029677 or an alternative shaft seal, verify the following:

1. Nominal shaft diameter of 65 mm.

2. Housing bore diameter of 80 mm.

3. Required axial width of 8 mm.

4. B1 seal profile and casing construction.

5. Compatibility of NBR with the operating lubricant.

6. Shaft surface condition and housing tolerances.

7. Operating speed, temperature and pressure requirements.

8. Original equipment reference and installation requirements.

Matching dimensions alone do not guarantee complete technical interchangeability.

The replacement seal must be suitable for the mechanical assembly and its operating conditions.

Installation and Operating Recommendations

Before installation, clean the housing bore and inspect the shaft surface for scratches, corrosion, grooves or excessive wear.

The seal should be pressed evenly into the housing using an appropriate installation tool that supports the casing without damaging the sealing lip.

The shaft and sealing lip should be prepared according to the equipment manufacturer's lubrication recommendations.

Avoid damaging or folding the lip when passing the seal over shaft shoulders, splines or sharp edges.

For applications requiring lubrication at the lip-to-shaft contact, the seal should not be operated dry.

Store the seal in a clean, dry environment away from direct sunlight, excessive heat and substances that could damage the elastomer.

Frequently Asked Questions - FAQ

What are the dimensions of CORTECO 01029677?

CORTECO 01029677 has nominal dimensions of 65x80x8 mm. The shaft diameter is 65 mm, the housing bore diameter is 80 mm and the axial seal width is 8 mm.

What does B1 mean in CORTECO 01029677?

B1 identifies a radial shaft oil seal construction with a metal outer casing and an elastomeric sealing lip. The profile designation is important when selecting a replacement seal.

What material is used in CORTECO 01029677?

The sealing element is made from NBR, or nitrile butadiene rubber. This elastomer is commonly used in sealing applications involving mineral-based oils and greases.

Is CORTECO 01029677 compatible with CLAAS and FENDT machinery?

The seal is associated with CLAAS reference 02380780 and FENDT reference X550132802000. Compatibility must be verified using the original equipment part number and the documentation for the specific machine.
