Product Description
The 31148 is a rotary lip seal for aircraft gearbox housings and rotating shafts. It combines an elastomeric lip with a metal case to retain lubricants while excluding contaminants from critical bearing surfaces. This seal installs as a press-fit into the bore and operates in high-speed rotary applications typical of engine accessory drives and transmission systems.
Construction follows SAE AIR7095 guidance for rotary lip seal performance. Verify bore sizing, shaft diameter, and material compatibility with your aircraft maintenance manual before installation to ensure proper fit and sealing integrity.
