CORTECO 49362530 NBR BA 115x140x13 Rotary Shaft Seal

CORTECO 49362530 NBR BA is a radial shaft seal measuring 115x140x13 mm, manufactured from NBR - nitrile butadiene rubber. The exact CORTECO design designation for this reference is BA. The seal is associated with Mercedes-Benz OE references 3039970647 and A3039970647.

CORTECO 49362530 - Characteristics

The technical identity of this specific product can be expressed as:

49362530 -> CORTECO -> NBR -> BA -> 115x140x13 mm -> radial shaft seal -> Mercedes-Benz 3039970647

The complete combination of reference, material, design and dimensions is important because several technically different shaft seals are available in the 115x140x13 mm size.

CORTECO 49362530 should therefore be identified by its complete specification rather than by dimensions alone.

Dimensions

The confirmed dimensions are:

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

The 115 mm dimension corresponds to the nominal inside diameter, while 140 mm is the nominal outside diameter.

When selecting a replacement, all three dimensions should be considered together with the NBR material and BA design.

BA Seal Design

The exact design designation assigned to CORTECO 49362530 is:

BA

The BA code is an integral part of the product specification. It distinguishes this reference from other CORTECO seals with the same nominal dimensions but different sealing profiles.

The technically precise identification is therefore:

CORTECO 49362530 + NBR + BA + 115x140x13 mm

The BA designation should not be replaced with B2, TC or another profile solely because another seal has identical dimensions.

NBR Material

CORTECO 49362530 is manufactured from NBR - nitrile butadiene rubber.

NBR is a commonly used elastomer in radial shaft sealing systems and is suitable for use with many mineral-oil-based lubricants and greases.

Material suitability must nevertheless be checked against the actual medium and operating conditions. No product-specific temperature range, maximum shaft speed or universal chemical compatibility is assigned here because these parameters have not been sufficiently confirmed for the exact CORTECO 49362530 configuration.

Radial Shaft Sealing

CORTECO 49362530 belongs to the group of radial shaft seals, also commonly described in English as:

rotary shaft seal
radial shaft seal
oil seal

The seal provides a sealing interface between a rotating shaft and stationary housing.

For this specific reference, the nominal dimensions are 115 mm inside diameter, 140 mm outside diameter and 13 mm width.

The exact fitting position should be determined from the relevant Mercedes-Benz OE application rather than inferred solely from the dimensions.

Mercedes-Benz OE 3039970647

The principal Mercedes-Benz OE reference associated with CORTECO 49362530 is:

MERCEDES-BENZ 3039970647

The same OE reference is also encountered with the Mercedes-Benz prefix:

A3039970647

Both formats are relevant when identifying the product in parts catalogues and when searching by the original equipment number.

Vehicle compatibility should still be verified against the specific vehicle or assembly before installation.

ELRING Cross-Reference

A confirmed cross-reference associated with CORTECO 49362530 is:

ELRING 019.364

This provides an additional identification route when comparing parts.

A confirmed cross-reference is more useful for product identification than dimensional similarity alone. The exact technical specification and application should nevertheless be checked before substitution.

CORTECO 49362530 vs CORTECO 12003473

This distinction is particularly important because both products have the same 115x140x13 mm dimensions and both use NBR.

CORTECO 49362530 -> NBR -> BA -> 115x140x13 mm -> Mercedes-Benz 3039970647

CORTECO 12003473 -> NBR -> B2 -> 115x140x13 mm -> MAN / Mercedes-Benz 0119975446

The products therefore differ in their design codes and OE references.

Identical dimensions and the same base elastomer do not establish technical interchangeability.

CORTECO 49362530 vs Other 115x140 Seals

Several technically different products exist around the same nominal dimensions:

CORTECO 49362530 -> NBR -> BA -> 115x140x13 mm

CORTECO 12003473 -> NBR -> B2 -> 115x140x13 mm

CORTECO 20029785 -> PTFE/TFE -> B1BAPTSLRSX7 -> 115x140x13 mm

CORTECO 20020387 -> FPM -> BASLDRLX7 -> 115x140x13.5 mm

GRN 115x140x13 -> NBR -> TC -> double-lip design

This demonstrates why shaft seals should not be selected solely by inside and outside diameter.

Selection and Interchangeability

When selecting a replacement for CORTECO 49362530, verify:

• CORTECO reference 49362530
• inside diameter: 115 mm
• outside diameter: 140 mm
• width: 13 mm
• material: NBR
• design: BA
• relevant OE reference
• construction of the proposed replacement
• exact installation/application requirements

Matching the 115x140x13 mm dimensions alone does not establish full technical interchangeability.

This is particularly important because CORTECO offers other seals with the same nominal dimensions but different materials and design codes.
