Needle Roller Thrust Bearings
Amigo Needle Roller Thrust Bearings are engineered with a form-stable cage designed to retain and guide a significant quantity of needle rollers accurately. These bearings deliver a high degree of stiffness while occupying minimal axial space, making them an optimal choice for applications demanding compact solutions. When the faces of adjacent machine components can function as raceways, Amigo Needle Roller Thrust Bearings require no additional space beyond that of a conventional thrust washer.
- Accommodate heavy axial loads and peak loads
Needle roller thrust bearings are designed to accommodate substantial axial loads and peak loads, facilitated by the minimal diameter deviation of the rollers within a single assembly. - Extended bearing service life
The service life of needle roller thrust bearings is enhanced by engineering the roller ends with a slight relief. This modification optimizes the line contact between the raceway and rollers, thereby reducing stress peaks.
Needle Roller Thrust Bearings are meticulously engineered to accommodate high radial load capacity and are extensively employed across numerous sectors. Their precision engineering and adaptability render them suitable for a multitude of applications, available in a diverse array of designs, variants, and sizes. Typical applications include:
- Automotive transmissions
- Hydraulic pumps
- Industrial gearboxes
- Clutches and compressors
- Agricultural machinery
- Machine tools
- Construction equipment
Needle Roller Thrust Bearings - Designs and Variants
Needle Roller and Cage Thrust Assemblies
Needle roller and cage thrust assemblies consist of needle rollers and a cage to keep the rollers in position, providing excellent axial load capacity. They are compact and commonly used in automotive transmissions, hydraulic pumps, and gearboxes, where space constraints and high axial loads are critical factors.
Double Direction Bearings
Double direction Needle Roller Thrust Bearings are designed to accommodate axial loads in both directions. They are ideal for applications that require axial movement in alternating directions, such as in construction machinery, clutches, and aerospace systems, offering robust performance and durability.
Needle Roller Thrust Bearings with a Centring Flange
Needle roller thrust bearings with a centring flange provide additional stability and alignment for precise load handling. These bearings are frequently used in applications such as machine tools, agricultural machinery, and power steering systems, where precise load distribution and minimal misalignment are essential for efficient operation.
