Dimensions

The complete seal dimensions are:

25x37x7 mm

• shaft diameter d: 25 mm

• housing bore diameter D: 37 mm

NBR Material

CORTECO 12010848 is manufactured from NBR - nitrile butadiene rubber.

NBR is one of the most widely used elastomers for radial shaft seals. It provides good resistance to many mineral oils and greases and is commonly used in industrial, automotive and mechanical sealing applications.

Suitability should always be checked against the actual operating medium, temperature, shaft speed and other application conditions.

BA Design

The CORTECO catalogue specifies the seal design as:

BA

The BA profile is an important identification parameter together with the 25x37x7 mm dimensions and NBR material.

Selection and Interchangeability

Before selecting an alternative to CORTECO 12010848, verify:

1. Shaft diameter 25 mm.

2. Housing bore diameter 37 mm.

3. Width 7 mm.
