CORTECO 01032577B 70x110x12/8 72 NBR BAU4SLX2 Simmerring® Radial Shaft Seal

CORTECO 01032577B is a Simmerring® radial shaft seal with basic dimensions 70x110x12 mm, manufactured from 72 NBR. The exact Freudenberg/CORTECO construction profile is BAU4SLX2, while the complete catalogue geometry is specified as 70x110x12/8 mm. The associated Freudenberg Trade No. is 82032577.

Complete technical identification:

CORTECO 01032577B + 70x110x12/8 + 72 NBR + BAU4SLX2

CORTECO 01032577B – Technical Characteristics

CORTECO 01032577B Dimensions

The basic installation dimensions are:

d: 70 mm – shaft diameter

D: 110 mm – outside diameter

main width: 12 mm

This is why the product is frequently searched for as:

CORTECO 70x110x12 Simmerring®

However, the more precise catalogue geometry is:

70x110x12/8 mm

The additional 8 mm value forms part of the specific seal geometry and should be retained in technical identification rather than reducing the product to a generic 70x110x12 oil seal.

BAU4SLX2 – Exact CORTECO / Freudenberg Profile

The exact construction designation is:

BAU4SLX2

This profile is an important part of the identity of CORTECO 01032577B.

It should not be replaced with generic designations such as TC, SC or another manufacturer-specific profile simply because the basic dimensions are the same.

For technical identification and B2B replacement searches, the preferred combination is:

01032577B + 70x110x12/8 + 72 NBR + BAU4SLX2

72 NBR – Material Specification

The specified material is:

72 NBR

This is more precise than describing the product only as an NBR seal and should therefore be retained in the technical specification.

The complete material and profile combination is:

72 NBR + BAU4SLX2

The material designation alone should not, however, be used to assign unverified reference-specific operating limits.

For this exact seal, no unsupported values should be assumed for:

• maximum operating temperature
• minimum operating temperature
• maximum pressure
• maximum shaft surface speed

Spring-Loaded Sealing Lip

The construction incorporates a garter spring.

The spring supports the primary sealing lip and helps maintain radial contact between the sealing edge and the rotating shaft.

This is an important construction characteristic when comparing CORTECO 01032577B with other seals having nominal dimensions of 70x110x12 mm.

Auxiliary Dust Lip

The seal also incorporates an auxiliary dust lip.

The additional lip provides a secondary barrier on the external side of the main sealing area and helps limit the ingress of external contamination toward the primary sealing lip.

Therefore, replacement selection should account for the complete lip arrangement rather than dimensions alone.

CORTECO 01032577 vs 01032577B

This product may be encountered under several related identifiers:

01032577 – previous CORTECO reference

01032577B – current CORTECO reference

82032577 – associated Freudenberg Trade No.

Including all three identifiers is useful for international B2B search because customers may work from older catalogues, service documentation, warehouse labels or existing components.

The primary current product entity should remain:

CORTECO 01032577B 70x110x12/8 72 NBR BAU4SLX2

New Holland OE 44882211

A corresponding OE reference associated with this seal is:

New Holland 44882211

This reference can assist with part identification where machine documentation uses the equipment manufacturer's OE number instead of the CORTECO number.

The OE cross-reference should not be interpreted as confirmation that the seal fits every New Holland machine. Exact machine and installation compatibility should be checked against the relevant parts documentation.

70x110x12 Oil Seal – Why Dimensions Alone Are Not Enough

A search for 70x110x12 oil seal identifies only the basic installation dimensions.

It does not establish:

• exact seal profile
• lip arrangement
• material compound
• presence of an auxiliary lip
• complete 12/8 geometry
• application requirements

For CORTECO 01032577B, the exact BAU4SLX2 profile and 72 NBR material are therefore important identification parameters.

A generic 70x110x12 rotary shaft seal should not automatically be considered equivalent.

Selection and Interchangeability

When selecting a replacement for CORTECO 01032577B, verify:

• current reference 01032577B
• previous reference 01032577
• Trade No. 82032577
• shaft diameter d: 70 mm
• outside diameter D: 110 mm
• main width 12 mm
• additional catalogue dimension 8 mm
• complete geometry 70x110x12/8 mm
• material 72 NBR
• exact BAU4SLX2 profile
• garter spring
• auxiliary dust lip
• requirements of the actual sealing position

Matching the basic 70x110x12 mm dimensions alone does not establish interchangeability.
