Thrust Ball Bearings
AMIGO Thrust ball bearings are available in single or double direction types. They are designed solely for axial loads and should not encounter any radial load.
- Separable and interchangeable
The components of AMIGO thrust ball bearings are separable and interchangeable, facilitating mounting, dismounting, and maintenance inspections. - Initial misalignment
Thrust ball bearings with sphered housing washers can accommodate initial misalignment. - Interference fit
Thrust ball bearings feature shaft washers with a ground bore for an interference fit, while the housing washer bore is turned and always larger than the shaft washer bore.
Thrust ball bearings are widely used in various industries. Their availability matches their versatility across numerous applications in a wide range of designs, variants, and sizes. Examples of applications include:
- Industrial fans
- Industrial pumps
- Metals
- Industrial transmissions
- Mining, mineral processing and cement
Thrust Ball Bearings - Designs and Variants
AMIGO Single Direction Thrust Ball Bearings
AMIGO single direction thrust ball bearings are designed to accommodate axial loads in one direction. These bearings ensure precise performance in high-load applications, providing stability and durability for various machinery setups.
AMIGO Double Direction Thrust Ball Bearings
AMIGO double direction thrust ball bearings handle axial loads in both directions, offering reliable performance in demanding applications. These bearings are ideal for situations where space-saving designs and high axial load capacity are needed.
AMIGO Bearings with Sphered Housing Washers
AMIGO bearings with sphered housing washers allow for self-alignment to compensate for misalignments. These bearings are particularly suitable for applications where axial loads and slight angular misalignments are present, ensuring smooth and consistent operation.
