CORTECO 01020064 FPM BACSL1X2 18x30x7 – Steering Gear Shaft Oil Seal (Simmerring)

Technical specifications – CORTECO 01020064

The manufacturer part number, dimensions, material, construction profile and application are based on the supplied product identification and OE references. Other technical parameters require confirmation in CORTECO documentation.

Understanding the CORTECO 01020064 FPM BACSL1X2 designation

What does the BACSL1X2 profile mean?

BACSL1X2 identifies a specific CORTECO radial shaft oil seal construction.

The specified product features an additional dust protection lip. However, the complete interpretation of the profile code, precise sealing lip geometry, supporting case construction and garter spring arrangement require confirmation in manufacturer documentation.

The complete BACSL1X2 designation should be preserved when identifying a replacement.

BACSL1X2 oil seal construction

Primary sealing lip

The primary sealing lip limits leakage of a compatible lubricant where the rotating shaft passes through the housing.

Its effectiveness depends on sealing contact geometry, shaft surface condition, lubricant compatibility and operating conditions.

Additional dust protection lip

The additional lip helps limit the entry of dust and other external contaminants into the primary sealing area.

This is particularly relevant in assemblies where contamination may affect the service life of mating surfaces.

The dust protection lip is not an independent pressure-retaining seal.

Supporting case construction

The precise construction of the outer sealing surface and supporting case should be established using CORTECO technical documentation.

The BACSL1X2 profile must not automatically be considered identical to a standard AO/TC design merely because both may include an additional dust protection lip.

FPM/FKM material – fluoroelastomer

FPM is a designation for fluorocarbon rubber used in technical sealing applications. FKM is another widely used designation for the same general elastomer family.

Typical properties of FPM/FKM

• Good resistance to many mineral oils.

• Good resistance to numerous lubricants.

• Generally high resistance to thermal ageing compared with many standard NBR compounds.

• Suitability for appropriately selected dynamic sealing applications.

• Material properties dependent on the specific compound and operating medium.

Is FPM suitable for high temperatures?

Fluoroelastomers generally offer good resistance to elevated temperatures.

However, a specific operating temperature range must not be assigned to CORTECO 01020064 without verified manufacturer data.

FPM/FKM versus NBR and ACM

In steering gear assemblies, compatibility with the specific lubricant or hydraulic fluid is particularly important.

Mounting dimensions – 18x30x7 mm

Nominal dimensions alone do not establish mounting tolerances, required shaft surface roughness or permissible radial runout.

Are all 18x30x7 oil seals interchangeable?

No. Oil seals with identical dimensions may differ in sealing material, lip geometry, outer construction and permissible operating conditions.

For steering gear applications, compatibility with the specific assembly must also be verified.

OE references – CORTECO 01020064

The following OE references have been supplied for CORTECO 01020064 FPM BACSL1X2 18x30x7 mm.

RENAULT TRUCKS – 5000820328

The reference 5000820328 supports product identification in RENAULT TRUCKS technical documentation and parts catalogues.

Before selection, verify the exact vehicle model, steering gear type and compatibility with the assembly manufacturer's reference.

ZF – 0770080204, 0770080220 and 0770198098C

These ZF references support identification of the oil seal in documentation for corresponding steering gear assemblies.

They must not automatically be treated as universally interchangeable across every steering gear version.

Final selection should be based on the OE reference, steering gear model and complete sealing profile.

Applications – steering gear shaft sealing

Steering gear shaft

CORTECO 01020064 is identified as a steering gear shaft oil seal.

Its function is to limit leakage of a compatible lubricant from the assembly while helping protect the primary sealing area against external contamination.

ZF steering gear assemblies

The supplied ZF OE references support identification of the product in parts catalogues for corresponding steering systems.

The exact steering gear model should be verified using its identification plate or technical documentation.

RENAULT TRUCKS commercial vehicles

The RENAULT TRUCKS reference 5000820328 indicates a catalogue association with relevant steering system components.

This does not establish compatibility with every RENAULT TRUCKS vehicle.

Operating conditions and technical limitations

Is this oil seal suitable for hydraulic power steering?

Its identification as a steering gear shaft oil seal does not establish its permissible operating pressure or compatibility with every hydraulic fluid.

For power-assisted steering systems, the sealing function, local pressure conditions and specified hydraulic fluid must be verified.

Comparison – BACSL1X2, BASL, AO/TC and A/SC

Can CORTECO BACSL1X2 be replaced with a standard AO/TC 18x30x7 oil seal?

Interchangeability cannot be established from dimensions and the presence of an additional dust protection lip alone.

The FPM material, exact BACSL1X2 geometry, steering gear requirements and OE reference must also be verified.

Product selection and interchangeability

Before ordering, verify:

• CORTECO manufacturer part number 01020064.

• Complete BACSL1X2 construction profile.

• FPM/FKM sealing material.

• Nominal dimensions 18x30x7 mm.

• Presence of the additional dust protection lip.

• RENAULT TRUCKS or ZF OE reference.

• Steering gear model and version.

• Lubricant or hydraulic fluid specification.

• Pressure conditions at the installation location.

• Mating shaft surface condition.

• Housing dimensions and installation depth.

• Steering gear manufacturer's installation requirements.

Matching dimensions of 18x30x7 mm alone does not establish interchangeability.

Installation of CORTECO 01020064

Before installation, confirm that the manufacturer part number, construction profile and dimensions match the steering gear documentation.

During installation:

• Clean the housing bore and shaft surface.

• Inspect the shaft for scratches, corrosion and wear.

• Protect the sealing lips from sharp edges.

• Use an appropriate installation tool.

• Press the oil seal evenly into position without tilting.

• Maintain the specified installation depth.

• Follow manufacturer instructions for sealing lip lubrication.

• Verify the correct installation orientation.

• Check sealing integrity after installation and startup.

For steering gear assemblies, the manufacturer's service procedures must be followed because incorrect installation may affect sealing performance and steering system safety.
