Simmering 85x115x15 NBR AO/TC

Shaft seal for industrial and automotive applications

Reliable rotary sealing with high durability

Main description

The Simmering 85x115x15 NBR AO/TC is a professional double lip oil seal designed for effective rotary shaft sealing in industrial machinery and automotive systems. Its primary function is to retain lubricants such as oils and greases inside the system while protecting the sealing area from external contaminants.

The AO/TC design features two sealing lips: a primary working lip responsible for oil retention and a secondary dust lip that protects against dirt, moisture and particles. Compared to a single lip seal, this configuration provides enhanced sealing performance, especially in demanding operating environments where shaft protection and reliability are critical.

Manufactured from NBR (nitrile rubber), this rotary shaft seal offers excellent resistance to mineral oils, greases, fuels and common technical fluids. NBR is widely used in technical sealing applications due to its good elasticity, wear resistance and dimensional stability, ensuring high durability and long service life under continuous operation.

With dimensions of 85x115x15 mm, the seal conforms to standard industrial sizing, allowing easy installation in housings and compatibility with common shaft diameters. The product is suitable as a shaft seal, oil seal, machine seal and engine seal in gearboxes, drive systems, bearing housings and rotating equipment used in industrial applications.

The Simmering 85x115x15 NBR AO/TC is a reliable solution wherever stable rotary sealing, resistance to oils and greases, and operational safety are required.

FAQ - frequently asked questions
