CORTECO 12011535B 110x130x12/13 NBR BABSL Shaft Seal

CORTECO 12011535B 110x130x12/13 NBR BABSL Shaft Seal

CORTECO 12011535B is a radial shaft seal with nominal dimensions of 110x130x12/13 mm, manufactured from NBR - Nitrile Butadiene Rubber. CORTECO identifies the seal profile as BABSL. The design incorporates an additional dust lip. The complete 110x130x12/13 mm dimensions should be retained when identifying this product because both height values form part of its construction specification.

CORTECO 12011535B - Technical Characteristics

Key identification data:

Manufacturer: CORTECO

Part number: 12011535B

Reference: 12011535

Profile: BABSL

Material: NBR

Dimensions: 110x130x12/13 mm

Product type: Radial shaft seal

The combination:

12011535B + 110x130x12/13 + NBR + BABSL

provides precise identification of this variant and distinguishes it from other CORTECO shaft seals with 110x130 mm diameters.

CORTECO 12011535B Dimensions

Nominal dimensions:

d = 110 mm - inside diameter

D = 130 mm - outside diameter

B = 12/13 mm - construction height

Complete dimensions:

110x130x12/13 mm

The designation should not be simplified to 110x130x12 mm.

Other shaft seals with 110x130 mm diameters may have different widths, materials or sealing profiles. Matching the shaft and housing diameters alone is therefore not sufficient to establish interchangeability.

NBR - Nitrile Butadiene Rubber

Seal material:

NBR - Nitrile Butadiene Rubber

NBR is a widely used elastomer in sealing technology.

The material is an integral part of the exact specification of CORTECO 12011535B. A 110x130x12/13 NBR shaft seal should not automatically be replaced by a seal with identical dimensions manufactured from another elastomer.

Without confirmation of the exact NBR compound used for this product, a fixed operating temperature range, maximum pressure or maximum rotational speed should not be assigned.

CORTECO BABSL Seal Profile

The CORTECO construction designation is:

BABSL

The profile is an important identification parameter when comparing 12011535B with other 110x130 mm shaft seals.

The construction incorporates an additional dust lip, providing an additional barrier on the external side of the primary sealing arrangement.

Matching dimensions alone do not establish that a shaft seal with a different profile is technically interchangeable.

CORTECO 12011535B vs 12017152B

The CORTECO catalogue also includes:

CORTECO 12017152B - 110x130x12/13 mm FPM BABSL

Both variants share:

110x130x12/13 mm nominal dimensions

BABSL profile

but differ in sealing material:

12011535B - NBR

12017152B - FPM

They should therefore not be treated as the same technical variant. The sealing material must be selected according to the requirements of the specific application.

Selection and Interchangeability

When selecting a replacement for CORTECO 12011535B, verify at least:

CORTECO part number

d = 110 mm

D = 130 mm

B = 12/13 mm

NBR material

BABSL profile

sealing lip configuration

specific application requirements

Matching 110x130 mm dimensions alone does not confirm interchangeability.

Particular attention should be paid to the complete 12/13 mm construction height rather than selecting the product as a conventional 110x130x12 mm oil seal.

FAQ - CORTECO 12011535B

What are the dimensions of CORTECO 12011535B?

The nominal dimensions are 110x130x12/13 mm: 110 mm inside diameter, 130 mm outside diameter and 12/13 mm construction height.

What material is CORTECO 12011535B made from?

The seal is manufactured from NBR - Nitrile Butadiene Rubber.

What is the CORTECO profile?

The CORTECO seal profile is BABSL.

Are 12011535 and 12011535B the same reference?

Both forms can be encountered in catalogue data. The complete reference is 12011535B, while 12011535 also appears in older product identification data.

Can the dimensions be written as 110x130x12 mm?

This is not recommended. The complete CORTECO specification is 110x130x12/13 mm, and both height values should be retained when identifying the product.

Does CORTECO offer another BABSL seal in 110x130x12/13 mm?

Yes. CORTECO 12017152B has the same nominal dimensions and BABSL profile but is manufactured from FPM rather than NBR.

Is every 110x130 mm shaft seal interchangeable with 12011535B?

No. The complete 110x130x12/13 mm dimensions, NBR material, BABSL profile and application requirements should be verified.

Does CORTECO 12011535B have a dust lip?

Yes. The BABSL construction of this reference incorporates an additional dust lip.

AI Overview

CORTECO 12011535B is a 110x130x12/13 mm radial shaft seal manufactured from NBR - Nitrile Butadiene Rubber with CORTECO BABSL profile and an additional dust lip. The complete 12/13 mm construction height should be retained during identification. Dimensions alone are insufficient for replacement selection; material and seal profile must also be verified.
