Rotary Shaft Seal Simrit 145x230x17 NBR BAUSLX2

Applications

The Simrit 145x230x17 NBR BAUSLX2 rotary shaft seal is a double lip oil seal designed for demanding industrial and automotive applications. It is used in gearboxes, engines, drive systems, pumps and heavy-duty machinery where reliable rotary sealing and protection against external contamination are essential. The BAUSLX2 design, featuring an additional dust lip, is particularly suitable for dusty environments and variable operating conditions.

Advantages

The double lip construction ensures effective oil and grease retention while simultaneously protecting the sealing area from dirt and debris. The NBR (nitrile butadiene rubber) material provides proven resistance to oils and grease, good elasticity and stable performance in standard industrial temperature ranges. A spring-loaded primary lip maintains constant contact pressure on the shaft, while the rubber-coated outer surface improves housing fit and simplifies installation. The result is high durability, reduced wear and long service life.

Main Description

The Rotary Shaft Seal Simrit 145x230x17 NBR BAUSLX2 is a professional oil seal developed for reliable shaft sealing in industrial and automotive systems. As a double lip rotary shaft seal, it combines effective lubricant retention with active protection against external contaminants, reducing the risk of leakage and premature component wear.

The NBR sealing lips offer stable resistance to mineral oils and greases, making this seal suitable for a wide range of industrial applications. The optimized lip geometry and integrated garter spring ensure uniform radial pressure on the shaft, supporting consistent sealing performance over long operating periods. The rubber-coated outer diameter enhances sealing in the housing bore and compensates for minor surface imperfections.

With its standard dimensions of 145x230x17 mm, this shaft sealing ring is commonly used in OEM production, maintenance and overhaul operations. The BAUSLX2 design is especially recommended for machines operating in contaminated environments, where additional dust protection is required. This rotary seal meets the expectations of B2B customers seeking durable, technically proven and repeatable sealing solutions.
