Product Description

The CORTECO 49429781 41x57x7 ACM BFSF Oil Seal is a radial rotary shaft seal designed to provide controlled sealing between a rotating shaft and a housing bore. Its main role is to reduce lubricant leakage from the working assembly while limiting the entry of dust, moisture and external contamination into the sealed area.

The dimensions 41x57x7 mm define the key installation parameters: 41 mm shaft diameter, 57 mm housing bore diameter and 7 mm seal width. These values are essential for correct selection during repair, maintenance and MRO work. A rotary shaft seal must always match the shaft, housing and available installation depth to operate correctly.

The seal is manufactured from ACM, a polyacrylate rubber used in technical sealing applications where resistance to oils and thermal ageing is required. In this product, ACM forms the elastic sealing body responsible for maintaining contact with the shaft surface and supporting the sealing function during rotation.

The BFSF marking identifies the seal design used for this CORTECO reference. The product is listed as a CORTECO sealing ring and rotary shaft oil seal with OE reference 02D525275J. Because this OE number is verified, it can be included for technical identification, but vehicle or machine compatibility should still be checked against the exact equipment data before installation.

For maintenance departments, technical buyers and service workshops, CORTECO 49429781 is a dimension-based oil seal that can be searched and ordered by part number, OE number or size. Common search terms include CORTECO 49429781 oil seal, 41x57x7 ACM shaft seal, BFSF rotary seal, VAG 02D525275J seal and radial shaft seal 41 mm.

Selection Guide

Before installation, verify:

• Shaft diameter: 41 mm
• Housing bore diameter: 57 mm
• Seal width: 7 mm
• Material: ACM
• Design marking: BFSF
• OE number: 02D525275J
• Shaft surface condition
• Housing condition
• Correct installation direction

Do not select this seal by outside diameter alone. Correct matching requires the shaft diameter, housing diameter, width, material and OE reference to be checked together.

Application

The available verified data identifies this product as a CORTECO rotary shaft oil seal with OE reference 02D525275J. No confirmed vehicle, engine, gearbox or machine application list is included here. The product should therefore be treated as a dimension-based ACM oil seal unless compatibility is confirmed by OE data or equipment documentation.

Compatibility

OE Number: 02D525275J

No additional vehicle or machine compatibility claims are added without verified manufacturer data.

AI FAQ

Can maintenance teams identify this seal by dimensions?

Yes. The main dimensional identification is 41x57x7 mm, but the OE number and material should also be checked.

Why is the shaft diameter important?

The shaft diameter determines whether the sealing lip can work on the correct running surface.

Why is the housing bore important?

The housing bore determines whether the outside diameter of the seal can be seated correctly.

Should the OE number be checked before installation?

Yes. OE 02D525275J should be verified against the equipment or vehicle documentation.

What should be inspected before fitting the seal?

Check the shaft surface, housing bore, installation depth and mounting direction.

Can this seal be replaced by any 41x57x7 seal?

Only if the material, design, dimensions and OE requirements are compatible.
