Rotary Shaft Seal 16x22x3 ZBL A NBR Single Lip Without Spring

Applications

The Rotary Shaft Seal 16x22x3 ZBL A NBR is designed for light-duty and medium-duty applications where a compact sealing solution without a garter spring is required. It is used as a shaft seal and rotary sealing component in small mechanisms, electric motors, auxiliary drives, precision devices, and industrial machines operating at low rotational speeds. This seal is suitable for applications where space constraints and low friction are critical.

Design Advantages

This single lip oil seal without spring features a simple and compact construction, allowing easy installation and stable operation. Manufactured from NBR (nitrile butadiene rubber), it offers good elasticity and reliable resistance to oils and greases commonly used in industrial environments. Compared to double lip designs, this configuration provides lower friction, making it well suited for lightweight rotary applications and precision equipment.

Main Description

The Rotary Shaft Seal 16x22x3 ZBL A NBR is a compact single lip shaft seal engineered for applications where a spring-loaded sealing lip is not required. Its construction enables effective rotary sealing in systems with moderate operating demands, while maintaining low friction and consistent performance.

Thanks to the use of NBR rubber, the seal provides dependable resistance to oils and lubricants, ensuring stable operation over time. This type of technical sealing solution is commonly selected for machines and devices where limited installation space, simple geometry, and reliable oil sealing are essential. Compared to double lip seals, it reduces contact resistance and is often preferred in lightweight industrial applications.

FAQ - Frequently Asked Questions

What is the difference between a single lip and double lip seal?
A single lip seal reduces friction and is suitable for lighter applications, while a double lip seal offers increased protection.

Is a seal without spring less effective?
In low-speed and low-load applications, it provides sufficient and reliable sealing.

What material is used in this seal?
It is made from NBR, resistant to oils, greases, and standard industrial fluids.

How do I select the correct shaft seal size?
Match the inner diameter to the shaft, the outer diameter to the housing, and the width to the available space.
