CORTECO 20029606 / 20029606B is a crankshaft radial shaft seal measuring 110x130x13 mm, manufactured with PTFE/ACM sealing technology. The original dimensional catalogue identifies the design as B1BAPTSLSFRSX37, while current catalogue data use the trade designation B1BASLSFRSX37FT. The seal features a left-hand twist, 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 product can be technically identified as:

CORTECO -> 20029606 / 20029606B -> PTFE/ACM -> B1BAPTSLSFRSX37 / B1BASLSFRSX37FT -> 110x130x13 mm -> left-hand twist -> dust lip -> mounting sleeve -> transmission-side crankshaft seal

This complete identification is important because a generic 110x130x13 mm oil seal is not necessarily technically interchangeable with CORTECO 20029606.

Dimensions

The confirmed dimensions are:

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

Both the historical CORTECO dimensional catalogue and current product catalogues confirm these dimensions.

PTFE/ACM Material

Current technical data specify the material combination as:

PTFE - polytetrafluoroethylene / ACM - polyacrylate rubber.

The older CORTECO dimensional catalogue uses the material abbreviation TFE, while contemporary catalogue data provide the more detailed PTFE/ACM description.

This material specification should be considered when selecting a replacement. A conventional NBR or FPM seal with identical dimensions should not automatically be considered equivalent.

B1BAPTSLSFRSX37 Seal Design

The older CORTECO dimensional catalogue identifies reference 20029606 as:

20029606 -> TFE -> B1BAPTSLSFRSX37 -> 110x130x13 -> MAN.

This confirms the B1BAPTSLSFRSX37 designation supplied in your product data.

Current TecDoc-derived product information uses the trade designation:

B1BASLSFRSX37FT Simmerring

and trade number:

82029606.

For SEO and historical product identification, it therefore makes sense to retain B1BAPTSLSFRSX37 while also including the current B1BASLSFRSX37FT designation in the technical specification.

Left-Hand Twist

CORTECO 20029606B is specified with a:

Left-hand Twist

directional sealing structure.

Directionality is an important characteristic of this crankshaft seal. A dimensionally identical seal with a different directional sealing structure should not automatically be treated as a replacement.

Additional Dust Lip

The product incorporates an additional dust lip. Current technical catalogues explicitly specify the seal as being supplied with dust lip.

This provides an additional protective barrier on the external side of the primary sealing area.

The presence of the dust lip should therefore be considered when comparing CORTECO 20029606B with alternative 110x130x13 mm seals.

Mounting Sleeve

CORTECO 20029606B is supplied with a mounting sleeve.

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

Correct installation is particularly important for PTFE-based crankshaft sealing designs.

Transmission-Side Crankshaft Seal

Current catalogue data classify CORTECO 20029606B as a crankshaft shaft seal and specify its fitting position as the transmission side / gearbox side.

It can therefore also be searched for as:

rear crankshaft seal
transmission-side crankshaft seal
MAN crankshaft oil seal 110x130x13
FENDT 824200210180 crankshaft seal
MAN 51015100218 oil seal

The exact OE reference should always be checked before installation.

FENDT OE Reference

The principal FENDT reference associated with CORTECO 20029606B is:

FENDT 824200210180.

Additional catalogue formats include:

F824200210180
X550174902000.

These references provide additional identification routes when searching agricultural machinery catalogues.

MAN OE References

The confirmed MAN OE numbers are:

MAN 51015100218
MAN 51015100281
MAN 51015107001.

All three references are consistently associated with CORTECO 20029606B in current parts catalogues.

For a specific MAN vehicle or engine, compatibility should nevertheless be verified by the OE number and exact application.

Additional OE References

Broader current catalogue data also associate CORTECO 20029606B with:

CASE: 3138701R91
DEUTZ: 12189888
DEUTZ: 01029752
MWM: 6.0496.12.9.1104
RENAULT: 6005005198
RENAULT: 7701021418.

These additional numbers can improve product identification in international search and AI systems, while the principal references for this product page remain FENDT and MAN.

Cross-References

Important aftermarket cross-references include:

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

These numbers provide useful additional routes for identifying the seal, although the full technical specification should still be compared before substitution.

CORTECO 20029606 vs Other 110x130 Seals

The CORTECO dimensional catalogue shows several technically different seals around the same nominal dimensions, including:

20029606 -> TFE -> B1BAPTSLSFRSX37 -> 110x130x13 mm

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

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

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

12012065 -> NBR -> B2SL -> 110x130x13 mm.

This is a strong example of why the dimensions 110x130x13 mm alone are insufficient to identify the correct shaft seal.

Selection and Interchangeability

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

• reference 20029606 / 20029606B
• inside diameter: 110 mm
• outside diameter: 130 mm
• width: 13 mm
• PTFE/ACM material specification
• B1BAPTSLSFRSX37 / B1BASLSFRSX37FT design
• left-hand directional 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 technical interchangeability.
