CORTECO 20029606 / 20029606B is a crankshaft radial shaft seal measuring 110x130x13 mm, manufactured with PTFE/ACM sealing technology. The original CORTECO designation is B1BAPTSLSFRSX37, while current catalogue data also use the trade designation B1BASLSFRSX37FT. The seal features a left-hand directional sealing structure, additional dust lip and mounting sleeve and is intended for installation on the transmission side of the crankshaft.

Important OE references include FENDT 824200210180 and MAN 51015100218, 51015100281 and 51015107001.

CORTECO 20029606 - Characteristics

The complete technical identity of the product can be expressed as:

CORTECO -> 20029606 / 20029606B -> PTFE/ACM -> B1BAPTSLSFRSX37 -> 110x130x13 mm -> left-hand twist -> dust lip -> mounting sleeve -> transmission-side crankshaft seal

This complete identification is important because several technically different radial shaft seals are available in the 110x130x13 mm size.

Dimensions alone should therefore not be used to determine interchangeability.

Dimensions

The dimensions of CORTECO 20029606 are:

Inside Diameter: 110 mm
Outside Diameter: 130 mm
Width / Height: 13 mm
Complete Size: 110x130x13 mm

All three dimensions should be considered together with the material, sealing design, directionality and OE reference.

PTFE/ACM Material

Current catalogue data specify the material combination as:

PTFE - polytetrafluoroethylene
ACM - polyacrylate rubber

The original CORTECO dimensional designation uses TFE, while contemporary product data provide the more detailed PTFE/ACM material specification.

This distinction is important when selecting a replacement. A conventional NBR or FPM radial shaft seal with identical dimensions should not automatically be considered technically equivalent.

B1BAPTSLSFRSX37 Seal Design

The original CORTECO designation for reference 20029606 is:

B1BAPTSLSFRSX37

Current catalogue data may also show:

B1BASLSFRSX37FT Simmerring

and trade number:

82029606

For product identification and search visibility, retaining the original B1BAPTSLSFRSX37 designation is useful, particularly when customers search using older technical catalogues.

Left-Hand Directional Design

CORTECO 20029606B is specified with a left-hand twist sealing structure.

Directionality is an important characteristic of this crankshaft seal. A seal with identical dimensions but a different directional sealing geometry should not automatically be considered a suitable substitute.

When selecting a replacement, the rotational relationship of the shaft and sealing structure must therefore be considered.

Additional Dust Lip

CORTECO 20029606B incorporates an additional dust lip.

The protective lip provides an additional barrier on the external side of the primary sealing zone and helps restrict external contamination from reaching the main sealing interface.

The presence of the dust lip is another technical parameter that differentiates this product from simpler 110x130x13 mm radial shaft seals.

Mounting Sleeve

CORTECO 20029606B is supplied with a mounting sleeve.

The sleeve assists correct installation of the sealing element and should be treated as part of the installation system.

Correct installation is particularly important with PTFE-based crankshaft seals to avoid damaging or deforming the sealing element during assembly.

Transmission-Side Crankshaft Seal

CORTECO 20029606B is a:

Crankshaft seal / radial shaft seal / oil seal

with the fitting position specified as:

Transmission Side / Gearbox Side

It can therefore also be described as a rear crankshaft seal in applications where the gearbox is mounted behind the engine.

This fitting position should be verified when selecting the product because a front crankshaft seal with similar dimensions may have a different construction.

FENDT OE 824200210180

The principal FENDT reference associated with CORTECO 20029606 is:

FENDT 824200210180

Additional catalogue formats may include:

F824200210180

This OE reference is particularly useful when identifying the seal for agricultural machinery applications.

Compatibility should still be checked against the exact tractor, engine and original equipment reference.

MAN OE References

The confirmed MAN references associated with CORTECO 20029606 are:

MAN 51015100218
MAN 51015100281
MAN 51015107001

These numbers provide a more precise method of identifying the correct seal than searching solely by the 110x130x13 mm dimensions.

For a specific MAN vehicle or engine, the OE reference should be verified before installation.

Additional Cross-References

Important aftermarket cross-references associated with CORTECO 20029606B include:

ELRING: 503.209
DT Spare Parts: 3.10043
FEBI BILSTEIN: 44579
GLASER: P76404-01
GOETZE: 5030511510
PAYEN: NA5181
VICTOR REINZ: 81-33801-00

Cross-reference numbers are useful for product identification, but the complete technical specification should still be compared before substitution.

CORTECO 20029606 vs Other 110x130x13 Seals

Several technically different CORTECO seals are available with the same nominal dimensions.

Examples include:

CORTECO 20029606 -> PTFE/ACM -> B1BAPTSLSFRSX37 -> 110x130x13 mm

CORTECO 12015384 -> FPM -> B1BAVISLRS -> 110x130x13 mm

CORTECO 12011364 -> NBR -> B1SL -> 110x130x13 mm

CORTECO 88018863 -> NBR -> B2 -> 110x130x13 mm

These examples demonstrate why the dimensions 110x130x13 mm alone are insufficient for selecting the correct crankshaft seal.

Selection and Interchangeability

When selecting a replacement for CORTECO 20029606 / 20029606B, verify:

• CORTECO reference 20029606 / 20029606B
• inside diameter: 110 mm
• outside diameter: 130 mm
• width: 13 mm
• PTFE/ACM material specification
• B1BAPTSLSFRSX37 design
• left-hand directional sealing structure
• additional dust lip
• mounting sleeve
• transmission-side fitting position
• relevant FENDT or MAN OE reference

Matching the 110x130x13 mm dimensions alone does not establish full technical interchangeability.
