Tapered Roller Thrust Bearings
Amigo Tapered Roller Thrust Bearings are engineered to withstand substantial axial loads and peak stress conditions. These bearings exhibit high rigidity and are optimized for applications requiring minimal axial space.
- Separable Design
The shaft and housing washers, along with the roller and cage thrust assemblies of tapered roller thrust bearings, can be installed independently, facilitating easier assembly and maintenance. - Low Friction
The advanced roller end design and flange surface finish optimize the formation of a lubricant film, significantly reducing friction, frictional heat, and flange wear. - Long Service Life
Crowned or logarithmic raceway profiles, depending on the design, enhance load distribution along contact surfaces, minimize stress peaks at roller ends, and reduce susceptibility to misalignment, outperforming traditional straight raceway profiles. - Enhanced Operational Reliability
The surface finish on roller and raceway contact surfaces promotes the development of a hydrodynamic lubricant film, improving operational reliability. - High Load Carrying Capacity
The rollers in tapered roller thrust bearings are manufactured to precise dimensional and geometrical tolerances, ensuring optimal load distribution and enabling the accommodation of substantial axial loads.
Tapered Roller Thrust Bearings are meticulously engineered for high axial load capacity and are widely employed across multiple industries. Their precision engineering and versatility make them ideal for a broad spectrum of applications, available in a comprehensive range of designs, variants, and sizes. Typical applications include:
- Heavy-duty gearboxes
- Crane hooks
- Oil drilling rigs
- Rolling mills
- Marine propulsion systems
- Industrial machinery
- Power generation equipment
- Automotive differentials
- Hydraulic presses
- Mining equipment
Tapered Roller Thrust Bearings - Designs and Variants
Single Direction Tapered Roller Thrust Bearings
Single direction tapered roller thrust bearings are designed to handle axial loads in only one direction. These bearings are commonly used in applications such as crane hooks, gearboxes, and oil drilling rigs, where precise axial load support is required in a single direction.
Double Direction Tapered Roller Thrust Bearings
Double direction tapered roller thrust bearings are capable of handling axial loads in both directions. They are often used in rolling mills, marine propulsion systems, and industrial machinery, where alternating axial forces need to be supported efficiently.
Screw-down Bearings
Screw-down tapered roller thrust bearings are specially designed for heavy-duty applications like steel rolling mills. These bearings support large axial loads in applications where precision alignment and load distribution are critical, such as in hydraulic presses and mining equipment. They ensure high performance and durability in demanding environments.
