CORTECO 19016577 Dimensions

The confirmed dimensions are:

Inside Diameter: 51 mm
Outside Diameter: 63 mm
Height 1: 8.5 mm
Height 2: 12 mm
Complete Size: 51x63x8.5/12 mm

NBR Material

CORTECO 19016577 is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is directly confirmed in product data for 19016577B.

NBR is widely used in radial shaft sealing technology for applications involving many mineral oils, greases and lubricants.

No exact product-specific temperature range, maximum shaft speed or pressure limit should be assigned to this reference without corresponding manufacturer documentation.

TB9 Seal Design

The confirmed design designation is:

TB9

The associated trade reference is:

82016577

The most precise technical identification is:

CORTECO 19016577 NBR TB9 51x63x8.5/12

The TB9 designation is an important part of the product specification. A radial shaft seal with identical nominal diameters but a different design should not automatically be considered equivalent.

Mazda OE B210-33-067

The Mazda OE reference corresponding to CORTECO 19016577 is:

MAZDA B210-33-067

Alternative format:

B21033067

The OE relationship with CORTECO 19016577B is consistently listed in aftermarket catalogue data.

A useful replacement identification sequence is:

Mazda B210-33-067 -> CORTECO 19016577 -> 51x63x8.5/12 mm -> NBR -> TB9

Mazda Wheel Hub Shaft Seal

CORTECO 19016577B is catalogued as:

For product identification, accurate search terms include:

Mazda wheel hub shaft seal
Mazda rear axle seal
Mazda B210-33-067 oil seal
Mazda B21033067 seal
CORTECO 19016577 Mazda

Selected Mazda Applications

Catalogue data associate this seal with selected Mazda 323 BF and BW applications, including certain four-wheel-drive versions.

The exact vehicle configuration should always be verified using the OE number, production period and installation position.

A vehicle model name alone is not sufficient for accurate replacement selection.

CORTECO 19016577 and 19016577B

The product may be encountered under:

CORTECO 19016577
CORTECO 19016577B

The associated trade reference is:

82016577

The TB9 designation also appears in catalogue data as an alternative product identifier.

Selection and Interchangeability

When selecting a replacement for CORTECO 19016577, verify:

• CORTECO reference 19016577 / 19016577B
• inside diameter 51 mm
• outside diameter 63 mm
• Height 1 = 8.5 mm
• Height 2 = 12 mm
• NBR material
• TB9 design
• Mazda OE B210-33-067 / B21033067
• exact installation position

A generic 51x63 mm shaft seal should not automatically be considered fully interchangeable with CORTECO 19016577.

The two height values 8.5/12 mm and the TB9 design are particularly important when comparing alternatives.
