CORTECO 49372000 Seal Ring / Rotary Shaft Seal 26.9x53x6 mm

Applications in Industrial & Automotive Use

The CORTECO 49372000 Seal Ring is designed as a high-durability rotary shaft seal for demanding industrial and automotive applications. With an inner diameter of 26.9 mm, an outer diameter of 53 mm and a height of 6 mm, this technical seal is suited for engine seals, oil seals, and shaft sealing rings in gearboxes, transmissions (notably referencing OEM code HU3R7048AHA), hydraulic and automotive seals. The use of ACM (polyacrylate) material delivers excellent resistance to oils and grease, making it ideal for applications where high durability and low maintenance is essential. Search trends show growing interest in terms such as “shaft seal 26.9x53x6”, “ACM oil seal”, “rotary seal dust lip”, “industrial shaft sealing ring” and “CORTECO seal ring 49372000”.

Advantages & Key Technical Features

• High durability and resistance to oils & grease: Constructed from ACM (polyacrylate) rubber, the seal ring performs reliably under exposure to lubricants, supporting keywords like “high durability”, “resistance to oils and grease”, “industrial applications”.

• Optimised design for rotary seal use: The swirl type is right-hand twist and the dust cover includes a dust lip, enhancing performance in rotating shaft environments and offering extra protection against contamination - aligning with search patterns like “rotary shaft seal dust lip”, “shaft sealing ring dust cover”.

• Compact dimensions for flexible integration: With 26.9 mm inner diameter x 53 mm outer diameter x 6 mm height, this seal fits standard housings and makes it relevant for procurement queries such as “seal ring 26.9x53x6”, “single lip oil seal 53 mm”, “uszczelnienie obrotowe 26,9x53x6”.

• Double-lip or single-lip equivalent performance: While being a robust single-lip or dust-lip “uszczelniacz wału”, the design supports applications that historically used double-lip seals-TC equivalents, capturing search interest in “single lip oil seal”, “double lip oil seal alternative”.

• Brand reliability and OEM compatibility: Produced by CORTECO and identified as part number 49372000 with EAN 3358960348159, the product supports OEM reference GETRAG HU3R7048AHA, aligning with B2B search interest in “CORTECO 49372000”, “HU3R7048AHA seal ring”, “engine seal CORTECO OEM”.

FAQ

Q1: What is the difference between a single-lip and a double-lip rotary shaft seal?
A: A single-lip oil seal has one sealing lip that interfaces with the rotating shaft and is often combined with a dust lip for external contamination protection. A double-lip seal has two sealing lips (one for fluid retention, one for contamination exclusion). The 49372000 seal ring uses a dust lip with ACM material, offering single-lip performance with enhanced external protection, bridging the functional gap.

Q2: Why choose ACM (polyacrylate) material for a shaft seal?
A: ACM is chosen for its strong resistance to oils, greases, and moderate temperatures, making it suitable for industrial and automotive environments. It provides “high durability” and “resistance to oils and grease”, key for applications where fluid contamination and long service intervals are important.

Q3: How do I select the correct shaft seal size for a bearing housing or drive unit?
A: Determine the shaft diameter (matching the inner diameter of the seal), the housing bore diameter (matching the outer diameter), and the installation height available (matching the height). For the CORTECO 49372000, dimensions are 26.9 mm (d) x 53 mm (D) x 6 mm (H). Also verify the seal type, swirl direction (right-hand twist) and presence of dust lip when selecting for rotary or engine applications.

Q4: What does the right-hand twist swirl type mean in a seal ring?
A: The swirl type describes the groove or pattern on the sealing lip that influences how the seal handles fluid and shaft rotation. A right-hand twist is optimised for shafts rotating in a standard direction (clockwise as viewed from one end) and helps channel fluid away from the sealing face, improving performance in high-speed or oil-rich environments.

Q5: What are the advantages for a B2B buyer choosing this model?
A: For industrial buyers, selecting the CORTECO 49372000 offers: precise dimensional fit, material suited for harsh fluid environments, contamination protection via dust lip, compatibility with OEM reference, reduced downtime, streamlined inventory (one seal for many uses) and fast dispatch from stock.
