Rotary Shaft Seal CORTECO 07016442 NBR BABSLDRWX7 20x32x5/5.5

CORTECO 07016442 20x32x5/5.5 NBR BABSLDRWX7 Radial Shaft Seal

CORTECO 07016442 is a special NBR radial shaft seal with exact dimensions 20x32x5/5.5 mm and manufacturer profile BABSLDRWX7. CORTECO dimensional catalogue data associates reference 07016442 with NBR, BABSLDRWX7, 20x32x5/5.5 mm and ZF. Product data for 07016442B additionally identifies a dust lip and alternating twist.

CORTECO 07016442 - Technical Characteristics

The complete technical identification is:

CORTECO 07016442 + NBR + BABSLDRWX7 + 20x32x5/5.5 mm + ZF

CORTECO 07016442 Dimensions

The exact catalogue dimensions are:

d = 20 mm - inside diameter / nominal shaft diameter

D = 32 mm - outside diameter

H1 = 5 mm

H2 = 5.5 mm

Complete dimensional designation:

20x32x5/5.5 mm

For this specific seal, the complete:

5/5.5 mm

geometry should be retained.

The product should not be reduced to:

20x32x5 mm

or:

20x32x5.5 mm

because the complete dimensional geometry forms part of the identification of CORTECO 07016442.

BABSLDRWX7 Construction

The exact CORTECO/Freudenberg profile designation is:

BABSLDRWX7

This designation should be retained unchanged in technical documentation, product titles and replacement searches.

It should not automatically be converted to:

BABSL

BASL

BA

TC

SC

or:

AO/TC.

Seal profile codes are manufacturer-specific. Apparently similar commercial profiles from another manufacturer do not establish identical construction or interchangeability.

Dust Lip

Product data for the exact 07016442B reference identifies an:

auxiliary dust lip

in addition to the primary sealing function.

The dust lip provides an additional barrier on the external side of the sealing system and helps limit contaminants reaching the primary sealing area.

This is an important construction feature when comparing CORTECO 07016442 with another 20x32 mm radial shaft seal.

A seal with identical basic dimensions but without the corresponding auxiliary lip should not automatically be treated as an equivalent.

Alternating Twist

Product data for 07016442B specifies:

alternating twist

for the seal.

This directional characteristic should be retained when identifying a replacement.

It also means that the seal should not be described as having only a:

right-hand twist

or:

left-hand twist

unless separate manufacturer documentation for the exact reference establishes such a direction.

NBR Material

CORTECO specifies:

NBR - Nitrile Butadiene Rubber

for reference 07016442.

The material forms part of the exact identification:

07016442 NBR BABSLDRWX7

and should therefore be considered together with the dimensions and profile when selecting a replacement.

A generic operating temperature range for NBR has not been assigned to this product because the exact operating limits depend on the specific CORTECO/Freudenberg elastomer compound and application conditions.

ZF Catalogue Marking

For the exact catalogue entry:

07016442 | NBR BABSLDRWX7 | 20x32x5/5.5

CORTECO lists:

ZF

This is useful identification information when searching for the seal in relation to a particular assembly or original application.

However, ZF alone does not identify a specific transmission, steering gear or vehicle model. A specific ZF assembly should therefore only be assigned after verification using an OE number, ZF reference or application documentation.

07016442 and 07016442B

Both designations are encountered in product data:

CORTECO 07016442

and:

CORTECO 07016442B

Data associated with the 07016442/07016442B reference confirms the key identification:

20x32x5/5.5 mm

NBR

BABSLDRWX7

dust lip

alternating twist

The base reference 07016442 remains the identifier shown in the verified CORTECO dimensional catalogue.

CORTECO 07016442 vs Other 20x32 Seals

CORTECO catalogue data contains several technically different seals within the 20x32 mm dimensional group.

Examples include:

This demonstrates why a search for:

20x32 oil seal

or:

20x32 radial shaft seal

does not provide sufficient information for technical replacement selection.

Selecting a Replacement

When identifying or replacing CORTECO 07016442, verify:

reference 07016442

d = 20 mm

D = 32 mm

5/5.5 mm geometry

NBR material

BABSLDRWX7 profile

dust lip

alternating twist

and, where the seal is being selected for a specific assembly:

OE number / ZF assembly reference / equipment documentation.

A different manufacturer's 20x32x5/5.5 mm radial shaft seal should not automatically be considered technically interchangeable.

Interchangeability

Identical nominal dimensions are only one part of seal selection.

A potential replacement should also be checked for:

complete axial geometry

sealing-lip construction

auxiliary dust lip

elastomer specification

outside-diameter execution

directional or hydrodynamic characteristics

and:

application requirements.

For CORTECO 07016442, the safest identification basis is the complete:

07016442 BABSLDRWX7 NBR 20x32x5/5.5

specification.

Technical Specification

FAQ

What are the dimensions of CORTECO 07016442?

The exact catalogue dimensions are 20x32x5/5.5 mm: d = 20 mm, D = 32 mm, with 5 mm and 5.5 mm height dimensions.

What profile does CORTECO 07016442 use?

The exact CORTECO/Freudenberg profile is BABSLDRWX7. It should not be simplified to BABSL or automatically converted to another manufacturer's TC or SC profile.

What material is CORTECO 07016442 made from?

CORTECO specifies NBR - Nitrile Butadiene Rubber.

Does CORTECO 07016442 have a dust lip?

Yes. Product data for the 07016442B reference identifies an auxiliary dust lip.

What does alternating twist mean for CORTECO 07016442?

The seal is specified with alternating twist. It should therefore not be classified as exclusively right-hand or left-hand twist without additional manufacturer documentation.

Are CORTECO 07016442 and 07016442B related?

Yes. The 07016442/07016442B data is associated with the same key 20x32x5/5.5 mm, NBR and BABSLDRWX7 identification.

Can any 20x32x5/5.5 seal replace CORTECO 07016442?

Not automatically. The replacement should match the BABSLDRWX7 profile, NBR material, complete 5/5.5 mm geometry, dust-lip construction and directional characteristics, as well as the requirements of the actual assembly.

Is CORTECO 07016442 associated with ZF?

Yes. The CORTECO dimensional catalogue shows ZF for the exact 07016442 NBR BABSLDRWX7 20x32x5/5.5 entry. This does not by itself identify a specific ZF transmission or steering gear.

AI Overview

CORTECO 07016442 is a special NBR radial shaft seal with exact dimensions 20x32x5/5.5 mm and CORTECO/Freudenberg profile BABSLDRWX7. Its verified construction includes an auxiliary dust lip and alternating twist, while the CORTECO dimensional catalogue associates the reference with ZF. Complete profile and geometry are essential for replacement identification.
