CORTECO 12010689 ACM BASLRD 45x65/70x10 mm - Radial Shaft Seal

CORTECO 12010689 ACM BASLRD 45x65/70x10 mm - Radial Shaft Seal

CORTECO 12010689 ACM BASLRD 45x65/70x10 mm is a radial rotary shaft seal manufactured from ACM polyacrylate rubber. Its distinctive 45x65/70x10 mm dimensional designation indicates a seal with a non-standard outer geometry, so it should not be treated as a conventional 45x65x10 mm shaft seal. The CORTECO profile designation is BASLRD.

CORTECO 12010689 - Technical Data

CORTECO 12010689 - Product Identification

The key identification data for this shaft seal are:

CORTECO 12010689

ACM

BASLRD

45x65/70x10 mm

Each of these parameters is important when selecting the correct seal.

Searching only for a seal with a 45 mm shaft diameter is not sufficient to confirm interchangeability.

What Does 45x65/70x10 mm Mean?

For CORTECO 12010689, the dimensional designation should be retained exactly as:

45x65/70x10 mm

The primary identification dimensions are:

45 mm - inside diameter

65/70 mm - characteristic outer dimensions resulting from the seal design

10 mm - width

The 65/70 mm designation is particularly important.

The product designation should not be simplified to 45x65x10 mm or 45x70x10 mm, as this would remove important information about the geometry of the seal.

ACM - Polyacrylate Rubber

CORTECO 12010689 is manufactured from ACM, or polyacrylate rubber.

ACM is an elastomer used in sealing technology, including radial rotary shaft seals for appropriately selected applications involving oils and lubricants.

However, the elastomer material is only one factor in determining whether a seal is suitable for a specific application.

Exact maximum temperature, pressure or rotational-speed limits should not be assigned to this specific product solely from typical ACM material properties.

Operating limits depend on the specific elastomer compound and the design and operating conditions of the complete sealing system.

CORTECO BASLRD Profile

BASLRD is the CORTECO profile designation for this seal.

The profile is an important part of product identification, particularly when several seals with similar dimensions are being compared.

The individual characters in the BASLRD designation should not automatically be interpreted using the nomenclature of unrelated seal manufacturers. Profile designation systems can be manufacturer-specific.

When selecting a replacement, the safest approach is to retain the complete identification:

Why Is the 65/70 mm Dimension Important?

Technical shaft seals can have more complex geometry than a conventional sealing ring with a single outside diameter.

For CORTECO 12010689, the 65/70 mm designation means that both dimensions should be considered during identification.

This is particularly important when:

comparing an existing seal

measuring the original component

searching for a replacement

selecting a seal by dimensions

comparing products from different manufacturers

identifying an unpackaged seal

A conventional 45x65x10 mm shaft seal should not automatically be considered an alternative to a 45x65/70x10 mm seal.

Likewise, a standard 45x70x10 mm seal does not automatically provide the same geometry.

How Does a Radial Rotary Shaft Seal Work?

A radial rotary shaft seal creates a sealing barrier between a rotating shaft and a stationary housing.

The primary sealing lip operates against the shaft surface to help retain lubricant within the protected assembly.

Correct sealing performance depends on several factors, including:

shaft diameter

seal geometry

sealing lip design

elastomer material

shaft surface condition

alignment

lubrication conditions

temperature

shaft surface speed

operating medium

For this reason, seals that appear visually similar are not necessarily technically interchangeable.

CORTECO 12010689 vs Standard 45x65x10 mm Seal

This distinction is important when searching for a replacement.

CORTECO 12010689 is specified as:

45x65/70x10 mm

not:

45x65x10 mm

A replacement should therefore not be selected solely on the basis of the three dimensions 45, 65 and 10 mm.

The complete geometry and the BASLRD profile should be considered.

CORTECO 12010689 vs 45x70x10 mm Seal

Similarly, a conventional shaft seal measuring:

45x70x10 mm

should not automatically be considered interchangeable.

CORTECO 12010689 has the specific dimensional designation:

45x65/70x10 mm

When replacing this seal, the CORTECO product number and complete dimensional and profile designation should be used for identification.

How to Select CORTECO 12010689

Before ordering, verify:

• CORTECO product number 12010689,
• complete dimensions 45x65/70x10 mm,
• 45 mm shaft diameter,
• complete 65/70 mm outer geometry,
• 10 mm width,
• ACM elastomer material,
• BASLRD profile,
• OE number where the seal is selected for a specific machine or vehicle,
• design and installation position of the original seal.

For a seal with this characteristic geometry, retaining the complete dimensional designation is particularly important.

Does the Same Shaft Diameter Mean Interchangeability?

No.

Two seals can both have an inside diameter of 45 mm while differing significantly in:

outside diameter

outer-case geometry

width

profile

material

sealing lip design

intended application

The shaft diameter is therefore only one of several identification parameters.

Do Similar Dimensions Mean Interchangeability?

No. Similar or partially matching dimensions do not automatically mean that two shaft seals are interchangeable.

For CORTECO 12010689, particular attention should be paid to:

45x65/70x10 mm

ACM

BASLRD

CORTECO 12010689

If an OE reference for the original seal is available, it should also be included in the identification process.

ACM seal 45x65/70x10

The version containing the slash should be retained because it helps distinguish this seal from standard 45x65x10 mm and 45x70x10 mm products.

Installation of CORTECO 12010689

Before installation, thoroughly clean the seal housing and shaft surface.

Check that the surface operating against the sealing lip is free from:

burrs

corrosion

sharp edges

deep wear grooves

damage that could cut the sealing lip

The seal should be pressed evenly into the housing using a suitable installation tool and without tilting.

Because of the characteristic 65/70 mm geometry, the correct orientation of the seal in relation to the housing should also be confirmed before installation.

Incorrect installation can damage the sealing lip, deform the outer section of the seal or cause leakage.
