Rotary Shaft Seal CORTECO 20026275 PTFE BASLRDX7 40x62x8

Application and Use

The CORTECO 20026275 PTFE BASLRDX7 rotary shaft seal 40x62x8 is a high-performance oil seal designed for demanding automotive and industrial environments. It functions as a precision rotary sealing solution for rotating shafts, ensuring reliable protection against oil and lubricant leakage even under high speeds and variable temperatures.

This shaft seal is widely used in OEM and aftermarket applications for vehicles and machinery of brands such as BMW, FORD, INNOCENTI, ISUZU, MERCEDES-BENZ, MITSUBISHI, OPEL, SMART, VAUXHALL, VOLVO and VW. Thanks to advanced PTFE technology, the seal delivers consistent performance in engines, gearboxes, and industrial drive systems.

Advantages of PTFE BASLRDX7 Technology

The BASLRDX7 profile combined with PTFE sealing lips provides exceptional durability and reduced friction compared to conventional elastomer seals. This design minimizes shaft wear and extends service life, making it ideal for high-duty rotary sealing applications.

Key benefits include:

• high resistance to oils and greases

• excellent chemical and thermal stability

• low friction for reduced shaft wear

• dry-running capability during installation

• long service life in continuous operation

This rotary shaft seal is recommended where standard rubber oil seals no longer meet durability or performance requirements.
