Product Description

CORTECO 49376103 is a radial oil seal designed for rotary shaft sealing. Its role is to create a controlled sealing barrier between a rotating shaft and the housing bore, helping retain lubricant inside the assembly and limiting the entry of contamination from the outside. In technical procurement, maintenance and repair work, this type of seal is commonly identified by the CORTECO part number, dimensions, construction code and OEM reference numbers.

The seal has a 90 mm inner diameter, 115 mm outer diameter and 12 mm width. The 90 mm dimension corresponds to the shaft diameter, the 115 mm dimension corresponds to the housing bore, and the 12 mm width defines the required installation space. These three values are critical during replacement, because a visually similar seal with different dimensions or construction may not provide the correct fit or sealing behavior.

This model is made from FPM fluoro rubber. FPM is used in technical sealing applications where the elastomer must maintain sealing contact on a rotating shaft. The material is part of the verified product specification, therefore it should not be replaced with NBR unless the equipment documentation clearly allows it. For maintenance teams and MRO departments, confirming the FPM material is important when matching the original seal specification.

The BASLX7 construction identifies this product as a specific CORTECO Simmerring design. BASLX7 should be treated as part of the technical identity of the seal, not as a decorative suffix. The confirmed dust lip provides an additional sealing feature intended to help protect the sealing area from external particles. This is important where the shaft seal operates in an exposed mechanical environment.

The operating principle of a radial shaft seal is based on the contact between the sealing lip and the rotating shaft. The lip forms a dynamic sealing line, while the outer diameter holds the seal in the housing bore. For correct installation, the shaft surface should be clean and free from damage in the lip contact area. The housing bore should also be clean, stable and suitable for secure seating of the seal.

CORTECO 49376103 is useful for technical buyers, service workshops and industrial maintenance teams because it can be identified by several confirmed OEM references: DOOSAN 218000888, JOHN DEERE T168903, LIEBHERR 571427508, TEREX 5904662279, TEREX 15500659 and VOLVO 002291594. These references reduce the risk of selecting the wrong rotary shaft seal when working from machine documentation, spare parts catalogues or existing part numbers.

Selection

When selecting CORTECO 49376103, verify:

• shaft diameter: 90 mm
• housing bore diameter: 115 mm
• seal width: 12 mm
• material: FPM fluoro rubber
• construction: BASLX7
• dust protection: with dust lip
• CORTECO part number: 49376103
• EAN: 3358960462466
• OEM reference number
• shaft surface condition
• housing bore condition

Do not select this seal only by appearance. Dimensions, material, BASLX7 construction and OEM reference should all match the required specification.

Application

CORTECO 49376103 is identified as a radial oil seal / rotary shaft seal. Its function is to seal a rotating shaft, retain lubricant and protect the sealing point from external contamination. Because the product has confirmed OEM references, it should be selected by comparing the part number with the original equipment documentation or spare parts catalogue.
