Rotary Shaft Seal CORTECO 20034573 110x130x12 PTFE - Oil Seal

Applications - Industrial & Heavy-Duty Machinery

The Rotary Shaft Seal CORTECO 20034573 (110x130x12 mm, PTFE, BAPTSLVRDX7) is a premium oil seal engineered for high-performance rotating systems operating under extreme pressure, high temperature, and chemically aggressive environments. Designed for heavy-duty industrial applications, it is widely used in construction machinery, hydraulic drives, power transmission systems, engines, gearboxes, and LIEBHERR equipment, fully compatible with OEM reference 51015100279.

Key Advantages of the CORTECO PTFE Rotary Seal

Manufactured using advanced PTFE (polytetrafluoroethylene) sealing material, this rotary shaft seal offers exceptional protection and long-term reliability in harsh working conditions. PTFE ensures:

• Extreme temperature resistance and reduced friction

• Superior durability against aggressive oils, hydraulic fluids and grease

• Low wear and long maintenance intervals

• Stable performance at high shaft speeds

• Enhanced sealing capability in contaminated and abrasive environments

The BAPTSLVRDX7 sealing profile provides precision sealing and protection from oil leakage, dirt and dust intrusion—ideal for applications where standard NBR/FPM seals would fail.

Technical Data

Main Description

The Rotary Shaft Seal CORTECO 20034573 110x130x12 PTFE is a high-precision shaft sealing ring specifically developed for demanding professional environments where maximum resistance to heat, pressure and chemical exposure is required. Designed for industrial and automotive hydraulic systems, this rotary oil seal ensures optimal shaft lubrication and prevents lubricant loss, contamination ingress and premature component wear.

Used extensively in LIEBHERR machinery, it delivers reliable sealing performance in engines, hydraulic pumps, heavy-duty transmissions, excavators and drive systems exposed to continuous mechanical load. The PTFE construction outperforms traditional elastomer-based solutions, making it ideal for extreme operating cycles, abrasive contaminants and high shaft surface velocity.

This oil seal is a direct replacement option for OEM components and supports maintenance professionals aiming for reduced downtime and extended equipment service life.

FAQ

Q1: What is PTFE and why is it better than NBR or FKM?
PTFE withstands extremely high temperatures, chemical exposure and high sliding velocities—ideal for heavy industrial systems that exceed the capabilities of NBR or FKM seals.

Q2: Is this seal compatible with LIEBHERR machines?
Yes — it corresponds to OEM reference 51015100279, commonly used in LIEBHERR construction and hydraulic equipment.

Q3: What is the purpose of a rotary shaft seal?
To prevent lubricant leakage and protect mechanical assemblies from dust, water, sludge and abrasive contaminants.

Q4: How do I verify the correct seal size?
Measure shaft diameter, bore diameter and seal width, ensuring exact fit (110x130x12 mm in this case).

Q5: Is this a double-lip seal?
Yes — the BAPTSLVRDX7 profile provides advanced multi-lip sealing geometry for high-pressure systems.
