Rotary Shaft Seal NBR 55x75x5.5 VRM01 DICHTOMATIK

Main description

The Rotary Shaft Seal NBR 55x75x5.5 VRM01 DICHTOMATIK is a precision radial shaft seal designed for reliable sealing of rotating shafts in industrial and automotive applications. Its primary function is to retain lubricants such as oils and greases inside mechanical assemblies while preventing external contaminants from entering the system. This type of technical sealing component is widely used wherever stable operation and protection of rotating equipment are required.

The seal is manufactured from NBR (nitrile butadiene rubber), a material known for its strong resistance to mineral oils, lubricating greases, and commonly used hydraulic fluids. NBR provides a balanced combination of elasticity, wear resistance, and dimensional stability, ensuring consistent sealing performance during continuous operation in standard industrial environments.

The VRM01 design features a metal outer case combined with a sealing lip supported by a tension spring. This construction maintains constant radial pressure on the shaft surface, compensating for minor shaft runout and surface wear. As a result, the seal offers effective leakage control, reduced risk of contamination, and extended service life of the sealed assembly.

With dimensions of 55x75x5.5 mm, this rotary shaft seal is commonly used in gearboxes, pumps, electric motors, compressors, and drive systems. The DICHTOMATIK brand is recognized in the B2B sector for consistent quality and reliable sealing solutions for industrial maintenance, OEM production, and technical service operations.
