Lifetime bearing protection increases mean time between failure (MBTF)
Extended bearing life
Consistent sealing performance
Non-wearing components
Engineered labyrinth design exclude contamination while retaining bearing lubrication, to IP 55 ratings
Non-wearing components means seal properties are not degraded over time
Faster mean time to repair (MTTR) during rebuilds
Eliminates repairs for shaft grooving
Eliminates repairs for seal housings
