Rotary Shaft Seal 40x48x4 NBR ZBA Oil Seal One Lip Without Spring

Construction and design

The Rotary Shaft Seal 40x48x4 NBR ZBA Oil Seal One Lip Without Spring is a compact sealing component designed for rotating shafts in mechanical systems where reliable oil sealing is required but installation space is limited. The seal features a simple and durable design suitable for light duty industrial applications.

Manufactured from NBR nitrile rubber, this oil seal offers excellent resistance to mineral oils, lubricating greases and many industrial fluids. The elasticity of the NBR material ensures stable contact between the sealing lip and the shaft surface, maintaining effective sealing during operation.

The ZBA construction indicates a single lip sealing design without a garter spring. The flexible sealing lip adapts to the shaft surface and provides reliable sealing in systems operating at moderate speeds and low pressure conditions.
