The AO 17x25x4 RICH is a micro Double Lip Oil Seal manufactured by RICH, specifically engineered for rotary shaft applications with extremely limited axial space. This seal efficiently retains crucial internal lubricants while the secondary lip provides an effective barrier against external contaminants like dust and moisture.
This model is characterized by its ultra-slim metric dimensions: 17 mm inner diameter, 25 mm outer diameter, and a remarkably thin 4 mm width. The double lip configuration ensures superior sealing integrity, performing both fluid containment and contaminant exclusion. Constructed from durable NBR (Nitrile Butadiene Rubber), the seal guarantees excellent chemical resistance to oils and fuels and maintains reliable performance across an operating temperature range of -30°C to +100°C. The slender 4 mm profile makes the AO 17x25x4 RICH an optimal choice for compact equipment, precision instruments, and applications requiring minimal axial footprint.
