BARS - Corteco Seal Design

The Corteco design designation for 12000688B is:

BARS

This design code is an important part of the technical identification of the seal.

The correct specification is:

58x85x8 mm + NBR + BARS + Left-Hand Twist

A generic radial shaft seal measuring 58x85x8 mm should therefore not automatically be considered equivalent to Corteco 12000688B.

Left-Hand Twist - Important Directional Feature

Corteco catalogue data identify this seal as:

LD

and parts catalogues specify:

Left-Hand Twist

This directional feature is important when selecting a replacement.

For Corteco 12000688B, the relevant combination is:

BARS + LD + Left-Hand Twist

The direction should therefore be verified in addition to the dimensions and material.

Lombardini 1213262 Oil Seal

Corteco 12000688B cross-references to:

LOMBARDINI 1213262

Identification:

Lombardini 1213262 -> Corteco 12000688B -> NBR BARS -> 58x85x8 mm -> Left-Hand Twist

The Corteco dimensional catalogue also associates reference 12000688B with Lombardini applications.

Slanzi 065268 / 65268 Oil Seal

Corteco 12000688B also cross-references to:

SLANZI 065268

The reference may also be searched without the leading zero as:

SLANZI 65268

Identification:

Slanzi 065268 -> Corteco 12000688B -> NBR BARS -> 58x85x8 mm

Keeping both 065268 and 65268 in the product content improves identification when the original number is entered in different formats.

What Does 58x85x8 Mean?

The dimensions specify:

58 mm - shaft diameter / inside diameter
85 mm - housing bore / outside diameter
8 mm - seal width

All three dimensions must correspond to the installation.

However, dimensions alone are not sufficient for Corteco 12000688B.

The complete technical identification also includes:

NBR + BARS + Left-Hand Twist

NBR Nitrile Rubber

Corteco 12000688B is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is widely used in radial shaft sealing applications and is suitable for use with many common mineral oils, greases and lubricants.

Actual compatibility depends on the operating medium and working conditions.

For Corteco 12000688B, the confirmed material is:

NBR

Corteco 12000688 vs Standard 58x85x8 Oil Seal

The dimensions:

58x85x8 mm

do not uniquely identify this Corteco seal.

Corteco 12000688B combines:

58x85x8 mm dimensions
NBR material
BARS design
LD / Left-Hand Twist

Therefore, a standard 58x85x8 radial shaft oil seal should not automatically be treated as a direct replacement.

Why Left-Hand Twist Matters

Corteco 12000688B is a directional shaft seal.

Its left-hand twist is part of the sealing configuration and is therefore relevant when comparing alternative seals.

The strongest technical identification is:

12000688B -> BARS -> NBR -> 58x85x8 -> LD

This distinguishes the product from dimensionally similar seals with a different design or directional characteristic.
