30x40x7 NBR Rotary Shaft Seal - SC Type Single Lip Oil Seal for Industrial Applications
The Rotary Shaft Seal 30x40x7 mm NBR SC Type - Single Lip is a high-quality oil seal designed to deliver reliable sealing performance in rotating shaft applications. Its SC profile (rubber-coated outer diameter with a single sealing lip and internal spring) ensures efficient sealing against lubricants and oils while maintaining low friction and heat generation.
Made of NBR (Nitrile Butadiene Rubber), this seal offers excellent resistance to mineral oils, greases, hydraulic fluids, and fuels, making it a top choice for standard industrial environments, including electric motors, gearboxes, hydraulic units, pumps, and agricultural machinery.
Its 30x40x7 mm dimensions correspond to standard housings and grooves, making it easy to install and interchange with other industry-standard seals. The single lip design is ideal for clean operating conditions where dust or contamination is minimal.
