The 20x26x4 RICH AO-type seal is a micro-sized double lip rotary shaft seal designed for compact sealing applications. With dimensions of 20 mm inner diameter, 26 mm outer diameter, and a narrow 4 mm width, it effectively prevents lubricant leakage and shields internal components from external contaminants such as dust and moisture.
Constructed from high-quality NBR nitrile rubber, this seal offers excellent resistance to mineral oils and maintains flexibility across a wide temperature range from –30°C to +100°C. The double lip design ensures bi-directional sealing: the primary lip retains internal fluids, while the secondary lip acts as a barrier against debris ingress.
This compact and robust seal is ideal for small-scale motors, precision instruments, and tight mounting environments where space and reliability are critical.
