Rotary Shaft Seal 42x62x10 NBR B1 - oil seal

Industrial and automotive applications

NBR material - durability and oil resistance

Technical fit and reliable rotary sealing

Rotary Shaft Seal 42x62x10 NBR B1 is a precision oil seal designed for effective rotary shaft sealing in industrial machinery and automotive systems. This single lip oil seal (B1 design) provides stable sealing performance where controlled retention of oils and greases is essential for reliable operation and long service life.

The seal features a metal outer case that ensures firm seating in the housing and consistent alignment during operation. The sealing lip is manufactured from NBR (nitrile rubber), a proven elastomer known for its resistance to oils and grease, mineral oils, lubricants and standard operating fluids. Thanks to these properties, the seal is widely used as a technical seal in gearboxes, pumps, electric motors, compressors and internal combustion engines.

With dimensions 42x62x10 mm, this rotary oil seal fits standard shafts and housings commonly used in industrial applications, maintenance operations and OEM assemblies. The single lip design ensures efficient shaft contact with low friction, reducing wear and heat generation during continuous or intermittent rotation. This makes the seal suitable for equipment operating under steady loads and variable speeds.

As a shaft sealing ring, the 42x62x10 NBR B1 oil seal is valued for its predictable performance, dimensional stability and ease of installation. It is frequently selected by B2B customers looking for dependable hydraulic and automotive seals that minimize downtime and support long-term machine reliability.

FAQ - frequently asked questions

What is a single lip oil seal (B1)?
It is a rotary shaft seal with one sealing lip and a metal outer case, designed to retain lubricants inside the system.

What are the advantages of NBR material?
NBR offers excellent resistance to oils and grease, good wear properties and stable performance in standard industrial conditions.

Where is a 42x62x10 rotary shaft seal used?
Commonly in gearboxes, engines, pumps, electric motors and general industrial machinery.

What is the difference between single lip and double lip oil seals?
A single lip oil seal retains the working medium, while a double lip oil seal also protects against external contamination.
