CORTECO 12011135 BASL 30x52x7 Rotary Shaft Seal

Applications - Reliable Rotary Sealing for Industrial and Agricultural Equipment

The CORTECO 12011135 BASL 30x52x7 rotary shaft seal is designed for effective shaft sealing in demanding industrial applications and agricultural machinery. This double lip oil seal (TC type) is commonly used in gearboxes, axles, hydraulic systems, and engine assemblies where consistent lubrication retention and contamination protection are critical.

Fully compatible with NEW HOLLAND 80378273, this seal ring is a trusted replacement component for service and maintenance operations. Its compact 30x52x7 dimensions ensure precise fitment in OEM housings without modification.

Advantages - BASL Double Lip Design in NBR Material

The BASL construction integrates a primary sealing lip with a dust lip, offering enhanced protection compared to a single lip oil seal (SC type). This configuration improves sealing efficiency in environments exposed to dirt, moisture, and agricultural debris.

Manufactured from NBR (nitrile butadiene rubber), the seal provides excellent resistance to oils and grease, stable elasticity, and long-term performance in standard temperature ranges. NBR remains one of the most widely used materials in hydraulic and automotive seals, delivering a balance between flexibility and mechanical strength.

As a professional rotary seal, this component ensures reduced leakage risk, improved shaft protection, and high durability in continuous-duty equipment.

Main Description

The CORTECO 12011135 BASL 30x52x7 oil seal is a precision-engineered rotary shaft seal developed for reliable performance in oil-lubricated systems. Designed as a shaft sealing ring with double lip configuration, it protects rotating shafts against lubricant leakage while preventing ingress of dust and external contaminants.

Its NBR compound ensures consistent elasticity and sealing pressure, even during extended operation. The BASL structure enhances sealing efficiency in comparison to standard single lip variants, making it suitable for equipment exposed to vibration, variable load, and environmental particles.

As a high-quality technical seal, this component is widely used as an engine seal, gearbox seal, and axle seal in agricultural and industrial equipment. Properly selected and installed, it supports long service intervals and minimizes downtime. For maintenance professionals and B2B buyers seeking a dependable rotary oil seal, the CORTECO 12011135 provides OEM-level performance with predictable reliability.

FAQ - Frequently Asked Questions

What is the difference between single and double lip oil seals?
A double lip oil seal includes an additional dust lip that improves contamination protection compared to a single lip seal.

Is NBR suitable for oil applications?
Yes, NBR offers very good resistance to mineral oils, grease, and typical hydraulic fluids.

How do I select the correct shaft seal size?
Match the inner diameter to the shaft diameter and the outer diameter to the housing bore. Width must also correspond to the housing depth.

Can this seal be used in agricultural machinery?
Yes, it is compatible with NEW HOLLAND 80378273 and suitable for heavy-duty agricultural equipment.

Is this seal suitable for high-temperature applications?
NBR performs well in standard industrial temperature ranges. For extreme temperatures, alternative materials such as FKM may be considered.
