Rotary Shaft Seal 210x240x15 NBR TC Oil Seal Double Lip

Rotary Shaft Seal 210x240x15 NBR TC Oil Seal Double Lip

Rotary Shaft Seal 210x240x15 NBR TC is a double lip oil seal designed to protect rotating shafts in industrial machinery operating in oil lubricated environments. Manufactured from durable NBR nitrile rubber, this rotary shaft seal provides reliable sealing performance by preventing lubricant leakage and protecting mechanical assemblies from contamination. The seal dimensions 210x240x15 mm make it suitable for large industrial drives, gearboxes and heavy duty equipment requiring stable and durable shaft sealing.

Rotary shaft seals NBR TC oil seals with double lip design are widely used in industrial equipment where long service life and reliable oil retention are essential. The primary sealing lip retains lubricating oil inside the system while the secondary dust lip protects the shaft from dirt, dust and external contaminants.

Industrial applications

The rotary shaft seal 210x240x15 NBR TC oil seal double lip is commonly installed in industrial equipment where rotating shafts must remain sealed under demanding operating conditions. Large diameter oil seals are particularly important in machines operating under continuous load and exposed to lubricants.

Typical industrial applications include:

industrial gearboxes
heavy duty pumps
large rotating machinery
industrial drive systems
construction and mining equipment
hydraulic power units

The seal size 210x240x15 mm is often used in large mechanical assemblies where reliable oil sealing and shaft protection are required.

Construction and design

The TC type rotary shaft seal features a double lip sealing design. The primary sealing lip maintains oil retention inside the machine housing, while the secondary lip acts as a protective barrier preventing dust and contamination from entering the system.

The seal body is manufactured from NBR nitrile rubber which offers excellent resistance to mineral oils, lubricants and petroleum based fluids. The metal reinforcement ring provides structural stability and ensures proper installation in the housing bore.

A spring loaded sealing lip maintains consistent contact pressure against the shaft surface, improving sealing performance and extending service life.
