Product Description

The CORTECO 49406861 is a radial shaft oil seal developed for differential applications. Its primary function is to provide reliable sealing between a rotating shaft and the housing, helping to retain transmission lubricant while reducing the ingress of dust, moisture and other external contaminants into the differential assembly.

The seal is manufactured from ACM (polyacrylate rubber), an elastomer widely used for sealing components operating with transmission oils and elevated temperatures. ACM offers good resistance to thermal ageing and lubricant exposure, making it suitable for demanding drivetrain sealing applications.

Its dimensions of 45x64.8x8.9/14.7 mm define the shaft diameter, housing diameters and installation heights required for correct fitment. Proper dimensional matching is essential for maintaining sealing efficiency and long service life.

The BFX7 design identifies the construction used by CORTECO for this seal. The manufacturer also provides OE references FIAT 55207480 and FIAT 552608520, enabling precise product identification during maintenance, repair and technical purchasing. Vehicle compatibility should always be confirmed using the OE reference or VIN before installation.
