Cylindrical Roller Thrust Bearings
Amigo Cylindrical Roller Thrust Bearings are engineered to handle substantial axial and impact loads with precision. These bearings are not designed to withstand any radial loads, ensuring optimal performance is maintained. Characterized by their high rigidity, they demand minimal axial space, making them an efficient choice for applications focusing on axial load management.
- Separable Design
The architecture of cylindrical roller thrust bearings facilitates independent mounting of the shaft washer, housing washer, and the cylindrical roller and cage thrust assembly. This separable design enhances the ease of installation and maintenance, allowing for efficient assembly and disassembly within complex systems. - Extended Bearing Service Life
The innovative modification of the line contact between the raceway and rollers is achieved by slightly relieving the roller ends. This design adjustment effectively mitigates stress peaks, thereby significantly prolonging the service life of the bearings by reducing wear and enhancing operational reliability.
Single Row Cylindrical Roller Thrust Bearings are engineered for high radial load capacity and are extensively utilized across various sectors. Their precision engineering and adaptability make them suitable for a multitude of applications, with availability in a diverse range of designs, variants, and sizes. Typical applications include:
- Industrial gearboxes
- Machine tools
- Heavy-duty cranes
- Hydraulic presses
- Extrusion machines
- Wind turbines
- Marine propulsion systems
- Mining equipment
- Steel mills
- Electric motors and generators
Cylindrical Roller Thrust Bearings - Designs and Variants
Single Direction Bearings
Cylindrical Roller Thrust Bearings in a single direction design are intended to support axial loads in only one direction. They are commonly used in applications such as industrial gearboxes, hydraulic presses, and machine tools where axial force needs to be managed efficiently and with stability.
Double Direction Bearings
Double direction Cylindrical Roller Thrust Bearings are designed to handle axial loads in both directions. These bearings are ideal for applications where there is a need to manage alternating axial loads, such as in heavy-duty cranes, wind turbines, and marine propulsion systems. Their robust design ensures they perform reliably in heavy load environments.
