Oil Seal NBR 64x84x10 AO/TC Double Lip Shaft Seal

Overview

Oil Seal NBR 64x84x10 AO/TC is a double lip rotary shaft seal with a 64 mm shaft diameter, 84 mm housing bore and 10 mm width. The AO/TC design combines a spring-loaded primary sealing lip with an additional dust lip. NBR provides reliable sealing performance with many mineral oils and greases used in industrial machinery and mechanical drive systems.

Industrial Applications

The 64x84x10 NBR AO/TC shaft seal is suitable for gearboxes, electric motors, pumps, reducers, hubs, production machinery and other rotary equipment. The primary lip retains lubricant inside the assembly, while the secondary lip provides additional protection against dust and fine external contaminants entering the sealing zone.

Construction

The AO/TC design incorporates two functional lips. The main spring-loaded sealing lip maintains controlled contact with the rotating shaft, while the auxiliary dust lip protects the primary sealing area from external contamination. The elastomer-covered outside diameter supports secure installation and static sealing within a correctly dimensioned housing bore.

Material

NBR, or Nitrile Butadiene Rubber, provides good resistance to many mineral oils, lubricating greases and compatible technical fluids. It combines useful wear resistance with mechanical properties suitable for standard rotary shaft sealing applications. Actual operating temperature capability depends on the specific NBR compound, lubricant and operating conditions.

FAQ

What does AO/TC mean for this 64x84x10 oil seal?

AO/TC identifies a double lip configuration with a spring-loaded primary sealing lip and an additional dust protection lip.

What shaft diameter is this oil seal designed for?

The nominal shaft diameter is 64 mm, with an 84 mm housing bore and 10 mm seal width.

What is the function of the secondary lip?

The secondary lip helps prevent dust and fine external contaminants from reaching the primary sealing area.

Is NBR suitable for oil sealing applications?

Yes. NBR provides good resistance to many mineral oils and lubricating greases, although compatibility should be verified for the specific medium.

What should be checked before replacing the seal?

Verify the 64x84x10 mm dimensions, AO/TC double lip design, NBR material, shaft surface condition, lubricant and operating temperature.
