Rotary Shaft Seal CORTECO 01035713 28x44x7 HNBR BASFX27 Oil Seal

Applications

The CORTECO 01035713 rotary shaft seal (28 mm bore x 44 mm outer diameter x 7 mm width) is a high-performance oil seal and shaft sealing ring designed for demanding industrial applications and automotive systems. Constructed with HNBR (hydrogenated nitrile butadiene rubber) and profile BASFX27, this technical seal ensures effective sealing in bearing housings, drive assemblies and engine systems requiring superior resistance to oils and grease, high durability, and reliable rotary sealing performance. Typical use-cases include motor shafts, pump bearings, gearbox outputs, industrial drive units and applications where a rotary seal must maintain integrity under dynamic loads and lubrication.

Advantages

• Premium material HNBR: Offers outstanding oil and grease resistance, excellent temperature performance and extended service life compared to standard elastomers.

• Optimised profile BASFX27: The sealing geometry provides robust containment of lubricants and effective exclusion of contaminants, reducing wear and friction.

• Standard dimensions (28x44x7 mm): Enables compatibility with common bearing housings and shaft assemblies, supporting swift maintenance and retrofit operations.

• Designed for industrial & automotive environments: Ideal for rotary seal, engine seal, bearing housing seal and hydraulic or power-transmission systems where reliability is critical.

• Technical seal built for longevity: Engineered as a high-durability component to reduce downtime and maintenance costs in B2B settings.

Main Description

For engineers, purchasing professionals and maintenance teams seeking a robust, ready-to-install rotary shaft seal, the CORTECO 01035713 (28x44x7 mm) stands out as a premium choice. This oil seal is crafted to deliver proven performance in environments where lubricant containment, contamination exclusion and bearing protection are mission-critical. Its design as a shaft sealing ring makes it especially suitable for use in bearing housings or as part of a unitised sealing solution in industrial drive systems.

Thanks to the advanced HNBR material, the seal offers exceptional resistance to oils and grease, retains flexibility under thermal stress and resists wear from rotary motion. The BASFX27 profile enhances performance by providing a double-lip design—or equivalent advanced sealing geometry—which combines primary fluid retention with secondary contaminant exclusion. With dimensions 28 x 44 x 7 mm, the seal integrates directly into standard assemblies, facilitating fast maintenance and reducing installation risk.

Whether you manage a production line, upgrade a drive unit, or specify components for a machine tool or automotive drivetrain, this rotary oil seal offers the performance foundation required for longevity. Its alignment with keywords such as “double lip oil seal”, “single lip oil seal”, “industrial applications”, “high durability” and “engine seal” ensures relevance for both search engines and end-users.

FAQ

Q1: What is the difference between a single lip oil seal and a double lip oil seal?
A1: A single lip oil seal features one contact lip that retains fluid. A double lip (or equivalent profile) adds a second lip or dust lip to exclude contaminants while retaining lubricant, enhancing performance in demanding environments.

Q2: Why is HNBR used for this rotary seal?
A2: HNBR (hydrogenated nitrile butadiene rubber) offers superior durability, higher temperature resistance and excellent resistance to oils and greases—critical for industrial and automotive shaft seal applications.

Q3: How do I choose the correct shaft sealing ring size?
A3: Measure the shaft diameter (in this case 28 mm), the housing bore outer diameter (44 mm), and the width or groove depth (7 mm). Ensure the seal material and profile suit the application’s speed, load, temperature and lubricant conditions.

Q4: Can this oil seal be used in bearing housings and industrial drive units?
A4: Yes. This rotary seal is ideal for bearing housings, drive units and other assemblies requiring effective sealing of rotating shafts in both industrial and automotive contexts.

Q5: What benefits does this seal bring to a unitised assembly?
A5: It provides reliable lubricant retention, protection against contamination, longer service life and reduced maintenance interventions—key factors for high-duty applications and cost-effective operation.
