Spherical Roller Thrust Bearings
Amigo Spherical Roller Thrust Bearings feature meticulously engineered raceways and asymmetrical rollers. These bearings are capable of supporting axial loads in a single direction, in conjunction with radial loads. Load transmission occurs between the raceways through the rollers, positioned at a specific angle relative to the bearing axis, with the flange providing precise guidance to the rollers.
- High Load Carrying Capacity
The extensive array of rollers, optimally conforming to washer raceways, facilitates the accommodation of heavy axial and concurrent radial loads. - Accommodate Misalignment
These bearings are self-aligning, effectively handling misalignment issues. - Separable Design
The separable nature of spherical roller thrust bearings allows for independent mounting and dismounting of the housing washer from the shaft washer and the roller and cage assembly, simplifying maintenance inspections. - High Speed Capability
The cage configurations and optimal roller conformity to washer raceways enable suitability for relatively high-speed applications. - Long Service Life
A specialized roller profile mitigates edge stresses at the roller/raceway interface, extending service life. - Low Friction
Optimized roller end/flange contact minimizes frictional heat generation, even at elevated speeds.
Spherical Roller Thrust Bearings are meticulously designed for exceptional axial and radial load capacity, making them indispensable across numerous industries. Their precision engineering and versatility render them ideal for a wide array of applications. These bearings are available in an extensive range of designs, variants, and sizes. Typical applications include:
- Industrial transmission
- Metals
- Pulp and paper
- Industrial fans
- Marine
- Mining, mineral processing and cement
