CORTECO 20020505B 133x160x15 FPM BASLRSX7 Rotary Shaft Seal

CORTECO 20020505B 133x160x15 FPM BASLRSX7 Rotary Shaft Seal

CORTECO 20020505B, also associated with reference 20020505, is an FPM radial rotary shaft seal measuring 133x160x15 mm. The verified CORTECO profile is BASLRSX7. Its key construction features include an additional dust lip and a left-hand hydrodynamic twist, making shaft rotation direction an important parameter when identifying and selecting this exact seal.

Exact identification:

CORTECO 20020505B / 20020505 – FPM – BASLRSX7 – 133x160x15 mm – left-hand twist – Trade No. 82020505 – EAN 3358960186393

CORTECO 20020505B BASLRSX7 – Technical Characteristics

CORTECO 20020505B is a radial rotary shaft seal designed to provide sealing at the interface between a rotating shaft and its surrounding housing.

The catalogue data for this exact reference identifies:

FPM material

BASLRSX7 profile

133 mm inside diameter

160 mm outside diameter

and:

15 mm height.

Catalogue data for 20020505B also identifies:

an additional dust lip

and:

left-hand hydrodynamic twist – Left-hand Twist.

The directional hydrodynamic feature is particularly important because it distinguishes this product from a generic non-directional FPM seal of the same nominal dimensions.

CORTECO 20020505B Dimensions

The catalogue identifies the third dimension as a 15 mm height. It is therefore not automatically labelled as B in this description.

The dimensional designation:

133x160x15 mm

alone is not sufficient for precise replacement identification.

For CORTECO 20020505B, the combination of:

133x160x15 mm + FPM + BASLRSX7 + left-hand twist + exact CORTECO reference

provides a much more precise technical identity.

BASLRSX7 Seal Construction

CORTECO 20020505B is designed to seal a rotating shaft where it passes through the corresponding housing.

For this exact reference, catalogue information confirms:

the primary rotary shaft sealing function

and:

an additional dust lip.

The dust lip provides an additional barrier on the external side of the sealing arrangement, helping limit the ingress of contamination toward the main sealing lip.

Another defining feature is its:

left-hand hydrodynamic twist.

This means CORTECO 20020505B should not be treated simply as any 133x160x15 mm FPM oil seal.

Left-Hand Hydrodynamic Twist

CORTECO 20020505B is specified with:

Left-hand Twist.

This describes the directional hydrodynamic structure associated with the sealing lip.

Hydrodynamic structures on rotary shaft seals interact with shaft rotation and the medium present in the sealing contact zone.

For replacement selection, the important practical conclusion is:

shaft rotation direction must be considered when selecting CORTECO 20020505B or a technically equivalent seal.

A seal with identical dimensions but a different hydrodynamic direction should not automatically be considered functionally interchangeable.

FPM Sealing Material

The confirmed material designation for CORTECO 20020505B is:

FPM.

FPM is a fluoroelastomer used for technical sealing applications.

However, the FPM designation alone does not establish the exact performance limits of this specific seal.

Therefore, this description does not assign an unverified:

FPM compound designation

Shore A hardness

operating temperature range

maximum shaft surface speed

or:

maximum operating pressure.

These values depend on the exact material compound, seal construction and operating conditions and should be taken from documentation applicable to the specific reference.

What Does BASLRSX7 Mean?

The exact profile listed for CORTECO 20020505 / 20020505B is:

BASLRSX7.

For product identification, the complete profile designation should be retained exactly as specified.

It should not be replaced with another BASL-type profile simply because the nominal dimensions and material appear identical.

Therefore:

BASLRSX7 is not equivalent to every BASL 133x160x15 FPM seal

and:

133x160x15 FPM does not automatically identify CORTECO 20020505B.

Profile geometry and directional characteristics must also be considered.

20020505 vs 20020505B

Both references may appear when searching technical and aftermarket catalogues:

20020505

and:

20020505B.

The product is currently commonly identified as:

CORTECO 20020505B,

while 20020505 remains a related reference found in catalogue data.

Another important identifier is the CORTECO trade/product number:

82020505.

For procurement and cross-checking, all three identifiers are useful:

20020505

20020505B

82020505.

OE References and Application Identification

Catalogue data associates CORTECO 20020505B with the following OE references:

DEUTZ / DEUTZ-FAHR 12152280

and:

DEUTZ / MWM 604960651332.

These references associate the seal with DEUTZ, DEUTZ-FAHR and MWM applications.

However, a manufacturer or machine family alone should not be used as the sole selection criterion. Different sealing variants may occur within related engines, transmissions or machine families.

A more robust identification method compares:

OE reference + CORTECO reference + dimensions + material + profile + hydrodynamic direction.

Selection and Interchangeability

CORTECO 20020505B should not be selected solely by searching for:

133x160x15 mm oil seal.

When comparing a possible replacement, verify:

133 mm shaft diameter

160 mm housing bore / seal outside diameter

15 mm axial height

FPM material requirement

seal profile

dust-lip construction

hydrodynamic direction

working-lip geometry

and:

OE or application documentation where applicable.

Identical dimensions do not establish full interchangeability.

For this particular reference, the:

left-hand hydrodynamic twist

is one of the most important parameters to verify.
