This high-quality 20x47x10 mm radial shaft seal, commonly known as an SPI seal or oil seal, is designed for demanding agricultural and industrial machinery. Manufactured from NBR (Nitrile Butadiene Rubber), it provides excellent resistance to oils, fuels, and hydraulic fluids. The seal features a single sealing lip with an additional dust lip (BA type) to prevent contamination and ensure reliable performance. Its precise dimensions (20 mm inner diameter, 47 mm outer diameter, 10 mm width) ensure a tight fit, preventing lubricant leakage and protecting bearings from dirt and moisture.
