Rotary Shaft Seal Simrit 32x50x14 COMBI SF14 NBR

Applications

The Simrit 32x50x14 COMBI SF14 NBR rotary shaft seal is a combined shaft sealing solution designed for industrial and automotive applications where effective oil retention and additional protection against contamination are required. The COMBI design integrates sealing and protective functions in one compact unit, making it suitable for engines, gearboxes, pumps, auxiliary drives and industrial machinery operating in demanding environments.

Advantages

The COMBI SF14 construction combines the functionality of a double lip oil seal in a single, space-saving design. The sealing element made of NBR (nitrile butadiene rubber) provides reliable resistance to oils and grease, stable elasticity and predictable performance under standard operating conditions. Optimized lip geometry and an integrated garter spring ensure constant contact pressure on the shaft, reducing leakage risk and minimizing wear. This seal is a direct replacement for Corteco 12013914, allowing easy integration in service and OEM applications.

Main Description

The Rotary Shaft Seal Simrit 32x50x14 COMBI SF14 NBR is a professional technical oil seal developed for reliable sealing of rotating shafts in industrial and automotive systems. As a COMBI shaft seal, it provides both effective lubricant retention and enhanced protection against external contaminants, helping to extend the service life of bearings and adjacent components.

The NBR sealing material offers proven resistance to mineral oils and greases, making this shaft sealing ring suitable for a wide range of industrial applications. The precisely engineered sealing lips, supported by a garter spring, maintain uniform radial pressure on the shaft, ensuring stable sealing performance and reduced friction over long operating periods. The compact design allows installation where space is limited, without compromising functionality.

With standard dimensions of 32x50x14 mm, this rotary seal is widely used in OEM production, maintenance and overhaul operations. As a compatible replacement for Corteco 12013914, it meets the expectations of B2B customers seeking durable, repeatable and technically proven sealing solutions for machinery and engine applications.
