CORTECO 20029785 B1BAPTSLRSX7 PTFE 115x140x13 Crankshaft Oil Seal

CORTECO 20029785 B1BAPTSLRSX7 is a PTFE crankshaft radial shaft seal measuring 115x140x13 mm. CORTECO dimensional documentation identifies the exact reference as 20029785 - TFE - B1BAPTSLRSX7 - 115x140x13 - MERCEDES TR. Current application data additionally confirm a dust lip, left-hand twist and transmission-end fitting position.

CORTECO 20029785 - Characteristics

The technical identity of this specific seal is:

20029785 -> CORTECO -> B1BAPTSLRSX7 -> PTFE/TFE -> 115x140x13 mm -> crankshaft oil seal -> transmission end -> dust lip -> left-hand twist

Current catalogues also use the reference CORTECO 20029785B.

This complete identification is important because CORTECO lists several technically different seals with dimensions 115x140x13 mm, including NBR and FPM variants with different design codes. Therefore, the dimensions alone do not identify CORTECO 20029785.

Dimensions

The confirmed dimensions are:

Inside Diameter: 115 mm
Outside Diameter: 140 mm
Width / Height: 13 mm
Complete Size: 115x140x13 mm.

The 115 mm value is the nominal inside diameter and 140 mm is the nominal outside diameter.

When identifying a replacement, the dimensions should be considered together with the B1BAPTSLRSX7 design, PTFE material and directional configuration.

B1BAPTSLRSX7 Seal Design

The CORTECO dimensional catalogue assigns the exact construction code:

B1BAPTSLRSX7

to reference 20029785.

This design code is an important part of the product specification. A generic 115x140x13 mm radial shaft seal may have a different material, sealing-lip arrangement or directional structure.

This is particularly relevant because CORTECO also lists other 115x140x13 mm seals under designations such as B1BASL, B1BASLX7, B1BAVISLRDX7, B1BAVISLRSX7 and B2.

PTFE / TFE Material

CORTECO's dimensional catalogue records the material abbreviation TFE for 20029785, while current product catalogues specify PTFE - polytetrafluoroethylene.

For an English product page, PTFE is therefore the clearer current material identification.

No specific temperature range, maximum shaft speed or universal media compatibility is assigned here because those parameters have not been verified for this exact CORTECO configuration.

Dust Lip

Current catalogue data specify CORTECO 20029785 with a dust lip.

The dust lip provides an additional barrier on the external side of the sealing area. Its presence should therefore be checked when evaluating an alternative 115x140x13 mm seal.

Left-Hand Twist

CORTECO 20029785 is specified with a left-hand twist.

This directional characteristic forms part of the seal construction and should not be ignored when selecting a replacement.

A seal with the same dimensions but a different directional design should not automatically be considered technically interchangeable.

Crankshaft Seal - Transmission End

Current catalogue data identify CORTECO 20029785 as a crankshaft shaft seal and specify installation at the transmission / gearbox side.

The technically useful identification is therefore:

CORTECO 20029785 -> crankshaft oil seal -> transmission end -> 115x140x13 mm -> PTFE -> B1BAPTSLRSX7

This is more precise than describing the product simply as a 115x140x13 Simmerring.

Mercedes-Benz OE References

The primary Mercedes-Benz reference associated with this product is:

0219975347

The same reference is also encountered in shortened database formatting as:

219975347

Current catalogues additionally associate CORTECO 20029785 with Mercedes-Benz references including:

0219972147
0259975047
259775047.

Corresponding A-prefixed Mercedes-Benz formats are also present in cross-reference catalogues.

Commercial Vehicle Cross-References

The supplied 219975347 / 0219975347 reference is associated in current catalogues with several commercial-vehicle manufacturers, including:

BREDAMENARINIBUS
DRÖGMÖLLER
FAP
MERCEDES-BENZ
NEOPLAN
PADANE
PLAXTON
SETRA.

These references provide useful product-identification routes. They should not, however, be interpreted as confirmation that CORTECO 20029785 fits every vehicle produced by these manufacturers.

Additional Cross-References

Cross-reference catalogues associate CORTECO 20029785 / 20029785B with parts including:

ELRING: 445.600
AJUSA: 15079000
FEBI BILSTEIN: 29824
PAYEN: NA5121
VICTOR REINZ: 81-36197-00.

These are stronger interchange references than dimensional similarity alone, but the specific application should still be verified before substitution.

Selection and Interchangeability

When selecting a replacement for CORTECO 20029785 / 20029785B, compare:

• inside diameter: 115 mm
• outside diameter: 140 mm
• width: 13 mm
• PTFE material
• B1BAPTSLRSX7 design
• dust lip
• left-hand twist
• crankshaft application
• transmission-end fitting position
• corresponding OE or confirmed cross-reference

A 115x140x13 mm dimensional match alone does not establish technical interchangeability.

This is especially important for this size because the CORTECO dimensional catalogue contains several 115x140x13 mm seals with different materials and design codes.
