CORTECO 19015774 NBR BABSL0.5 Oil Seal 28x40x6/5.5 - Rotary Shaft Seal

Applications

The CORTECO 19015774 oil seal, sized 28 mm inner diameter x 40 mm outer diameter x 6/5.5 mm width and built in NBR material with BABSL0.5 double-lip design (including dust lip), is engineered for demanding rotary shaft sealing applications. As a premier rotary shaft seal and oil seal variant, it meets the needs of industrial and automotive markets, especially for drive shafts, gearboxes, bearing housings, hydraulic/pneumatic actuators and engine shafts. The inclusion of the dust lip enhances contaminant protection, making this shaft sealing ring ideal for systems requiring high durability and resistance to oils and grease. This technical seal is aligned with OEM reference ZF 0770198036, making it a reliable choice for maintenance teams, procurement of sealing components and B2B supply chains.

Advantages

• High durability: The NBR (nitrile butadiene rubber) elastomer offers excellent resistance to mineral oils, lubrication greases and typical industrial environments, supporting long service life and lower downtime.

• Double-lip oil seal design with dust lip (BABSL0.5): The twin-lip profile ensures robust sealing of the shaft interface while the additional dust lip guards against external contaminants—ideal for harsh environments and rotating shaft assemblies.

• Precision sealing ring format: With dimensions 28x40x6/5.5 mm, this rotary seal can be seamlessly integrated into standard bearing housings or engine drive modules, simplifying inventory and maintenance logistics.

• Industrial and automotive readiness: Whether used as an engine seal, hydraulic actuator seal or in transmission systems, this technical seal meets the demands of industrial applications requiring shaft sealing ring solutions with minimal maintenance and high reliability.

• Optimised for rotary motion: Designed to maintain sealing integrity under shaft rotation, the seal addresses both dynamic and static sealing requirements, supporting both high-speed and moderate-speed shaft applications in B2B contexts.

FAQ

Q1: What distinguishes a double lip oil seal with dust lip from a standard single lip seal?
A dual-lip seal provides an extra sealing interface, and when coupled with a dust lip, it also protects the main sealing lip from external contamination (dust, dirt, debris). This design enhances sealing performance and extends seal life compared to a single lip solution.

Q2: Why is NBR chosen as the material for this oil seal?
NBR is selected for its strong resistance to mineral oils, grease and typical industrial chemical exposure. Its durability and balance of elasticity and strength make it well-suited for rotary shaft seal applications where both dynamic and static sealing occur.

Q3: How do I ensure correct sizing of the shaft seal for my application?
Measure the shaft diameter (inner diameter of the seal), the housing bore (outer diameter of the seal) and the width/thickness of the required seal. In this case, 28x40x6/5.5 mm design refers to these dimensions. Additionally consider rotational speed, environment (dust, contamination) and the presence of lubricant to select the appropriate seal profile.

Q4: In what industrial applications is this rotary shaft seal commonly used?
This oil seal is used in transmissions, gearboxes, engine drives, bearing housings, hydraulic and pneumatic actuators, and other rotating shaft arrangements where sealing of lubricant and exclusion of contaminants are essential.

Q5: Is this product suitable for B2B procurement and bulk inventory?
Yes. Its standard dimensions, strong brand (CORTECO), material quality and suitability for industrial and automotive contexts make it ideal for procurement, inventory management and efficient replacement in maintenance programs.
