PRODUCT OVERVIEW
29330 — Thrust Spherical Roller Bearings
Spherical rollers and a spherical housing raceway provide axial load capacity with self-aligning capability. Selected arrangements can also support radial load alongside the axial load.
Radial load, minimum axial load, lubrication and operating speed must be reviewed together for each application.
Typical application areas: Vertical reducers, Water turbines, Marine shaft systems, Vertical pumps. Suitability is reviewed against the specific operating conditions and bearing arrangement.
