Freudenberg Sealing Technologies Simrit Rotary Shaft Seal 72 Nitrile Butadiene Rubber 902, 25 mm ID, 52 mm OD, 10 40412323

Freudenberg Sealing Technologies Simrit 40412323 rotary shaft seal is expertly engineered from 72 Nitrile Butadiene Rubber 902 material, designed for durability and high wear resistance. This seal features an internal diameter of 25 mm, an external diameter of 52 mm, and a thickness of 10 mm, ideal for use in sealing rotary shafts within a broad range of industrial machinery.

This high-performance Simmering shaft seal delivers exceptional performance across numerous industries including aerospace, railway, power transmission, automotive, machine tools, fluid handling, production line, energy, and power generation sectors. The elastomer outer casing made from NBR 902 nitrile rubber paired with a spring loaded sealing lip provides superior sealing efficiency with both mineral and synthetic oils and greases.

The seal design ensures reduced friction torque by approximately 80%, lower heat generation by 50%, and greater resistance to wear, resulting in lowered power loss and extended working life. These improvements contribute to reduced maintenance costs and minimize costly downtime due to seal repairs.

Pressure stability up to 0.5 bar and ability to operate on bidirectional rotating shafts with velocities up to 40 meters per second ensures broad applicability.

Its precision manufacturing with ISO h11 shaft tolerance and H8 housing bore tolerance enhances performance reliability. Originating from the Czech Republic, this seal meets stringent quality and performance benchmarks.
