Cassette seals
The cassette seals are generally made up of a sleeve, sealing lip with a spring and several anti-dust lips integrated into a labyrinth system to protect against external pollution, and are distinguished by greater system reliability and longevity. Furthermore, their friction surface, which has been adjusted and finished beforehand, does not require any shaft maintenance during replacement.

UA15A
   The UA15A profile is a cassette seal, where sealing is through a 5-barrier labyrinth system. The upper part is static with the housing and the lower part is designed to operate in rotation with the shaft. This profile is the evolution of UA16A and offers better resistance over time in extreme conditions.

UA15B
   The UA15B profile is a cassette seal, where sealing is through a 5-barrier labyrinth system with 2 sealing lips prestressed with 2 loaded-springs. The upper part is static with the housing and the lower part is designed to operate in rotation with the shaft. This profile is the evolution of UA16B and offers better resistance over time in extreme conditions.

UA15C
    The UA15C profile is a cassette seal, where sealing is through a 4-barrier labyrinth system. The upper part is static with the housing and the lower part is designed to operate in rotation with the shaft. This profile is the evolution of UA50 and offers better resistance over time in extreme conditions.
