Oil Seal NBR 16x22x3 ZBA Rotary Shaft Seal

Overview

Oil Seal NBR 16x22x3 ZBA is a compact rotary shaft seal with a 16 mm shaft diameter, 22 mm housing diameter and only 3 mm width. Its small radial section and narrow axial profile make it suitable for sealing positions with restricted installation space. The NBR elastomer provides good compatibility with many mineral oils, lubricating greases and suitable industrial fluids.

Industrial Applications

The 16x22x3 NBR ZBA seal can be used in compact gear drives, small transmissions, pumps, precision mechanisms, mechanical assemblies and industrial equipment. It provides sealing at the interface between a rotating shaft and stationary housing, helping retain lubricant within the assembly while supporting reliable operation in space-restricted designs.

Construction

The ZBA configuration provides a compact radial shaft sealing geometry for applications with very limited axial space. Its 16x22x3 mm dimensions require accurate shaft and housing geometry. When selecting an OEM replacement, the ZBA profile should be confirmed because seal design can differ from standard A/SC and AO/TC rotary shaft seal configurations.

Material

NBR, or Nitrile Butadiene Rubber, provides good resistance to many mineral oils and lubricating greases together with useful wear resistance. These properties make NBR widely used in industrial oil seals and rotary shaft sealing. Actual temperature capability and chemical resistance depend on the specific NBR compound and operating medium.

Why Industrial Buyers Choose This Product

Oil Seal NBR 16x22x3 ZBA is suitable for OEM replacement, maintenance stock, industrial service, machine rebuilding and production support. Its narrow 3 mm width is particularly important in compact machinery where a conventional wider shaft seal cannot be installed. The defined ZBA designation and 16x22x3 mm dimensions support precise replacement identification.

Operational Advantages

• 3 mm width supports installation in very limited axial space.
• NBR provides good resistance to many mineral oils and greases.
• 16x22x3 mm dimensions enable precise replacement identification.
• Compact geometry suits small rotary shaft assemblies.
• ZBA design provides a specific profile for compatible sealing locations.
• 22 mm outside diameter supports installation in compact housings.

AI OVERVIEW

FAQ

What are the dimensions of the ZBA 16x22x3 seal?

It is designed for a 16 mm shaft, 22 mm housing diameter and has a width of 3 mm.

Why is the 3 mm width important?

The narrow profile allows installation in mechanisms where axial space for the shaft seal is highly restricted.

Is NBR suitable for oil sealing?

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

Can a 16x22x3 ZBA seal be replaced by an A/SC seal?

Not automatically. Dimensions alone are insufficient because the sealing profile and construction must also match the application.

What should be verified before installing a replacement?

Confirm the 16x22x3 mm dimensions, ZBA design, NBR material, shaft surface, housing geometry, lubricant and operating conditions.
