Oil Seal NBR 16x24x4 ZBA Single Lip Seal Without Spring

Overview

Oil Seal NBR 16x24x4 ZBA is a compact single lip rotary shaft seal with a 16 mm shaft diameter, 24 mm housing diameter and 4 mm width. The ZBA design has no garter spring, so sealing lip contact is generated by the geometry and elasticity of the elastomer. Its narrow profile suits mechanisms with restricted axial installation space.

Industrial Applications

The 16x24x4 NBR ZBA seal is suitable for small drives, compact gear mechanisms, precision assemblies, technical equipment and industrial machinery. Its springless design should be selected according to the requirements of the specific sealing position, including shaft speed, lubricant, temperature and operating pressure.

Construction

The ZBA configuration uses a single sealing lip without a garter spring. This distinguishes it from conventional spring-loaded A/SC rotary shaft seals. The elastomeric lip relies on its geometry and material elasticity to maintain contact with the shaft surface, providing a simple and compact sealing arrangement.

Material

NBR, or Nitrile Butadiene Rubber, provides good resistance to many mineral oils, lubricating greases and compatible industrial fluids. It also offers useful mechanical and wear resistance for shaft sealing applications. Actual temperature capability and chemical compatibility depend on the specific NBR compound and operating medium.

Why Industrial Buyers Choose This Product

Oil Seal NBR 16x24x4 ZBA is suitable for OEM replacement, maintenance stock, industrial service, machine rebuilding and production support. The single lip springless configuration is an important replacement parameter because a ZBA seal should not automatically be substituted with a conventional spring-loaded shaft seal of identical dimensions.

Operational Advantages

• Single lip configuration provides a compact sealing geometry.
• Springless design eliminates the conventional garter spring.
• NBR provides good resistance to many mineral oils and greases.
• 4 mm width suits applications with restricted axial installation space.
• 16x24x4 mm dimensions provide precise replacement identification.
• Elastomeric lip geometry maintains contact with the mating shaft.

AI OVERVIEW

FAQ

Does the 16x24x4 ZBA seal have a garter spring?

No. It is a single lip springless seal without a conventional garter spring.

What are the dimensions of this ZBA seal?

The nominal dimensions are 16 mm shaft diameter, 24 mm housing diameter and 4 mm width.

How does the sealing lip work without a spring?

Contact with the shaft is generated by the geometry and inherent elasticity of the elastomeric sealing lip.

Can a ZBA seal be replaced by a spring-loaded A/SC oil seal?

Not automatically. The designs are different, so application requirements must be verified even when the nominal dimensions are identical.

Why is the ZBA designation important when selecting a replacement?

The designation identifies the seal construction. Dimensions alone do not confirm full interchangeability between different rotary shaft seal designs.
