Single Row Tapered Roller Bearings
Single row tapered roller bearings are designed to handle combined radial and axial loads. Their raceway projection lines meet at a common point on the bearing axis to ensure true rolling action, resulting in low friction. The axial load capacity increases with a larger contact angle, typically between 10° and 30°, which is related to the calculation factor e; a larger e value means a larger contact angle.
- Low friction
AMIGO Single row tapered roller bearings have an optimized roller end design and surface finish on the flange, promoting lubricant film formation for lower friction. This reduces frictional heat and flange wear, helps maintain preload, and ensures quieter operation. - Long service life
The crowned raceway profiles of basic design bearings and the logarithmic raceway profiles in AMIGO bearings optimize load distribution, reduce stress at roller ends, and lessen sensitivity to misalignment and shaft deflection compared to conventional profiles. - Enhanced operational reliability
Optimized surface finishes on rollers and raceways in AMIGO bearings support the formation of a hydrodynamic lubricant film. - Consistency of roller profiles and sizes
AMIGO bearings feature rollers manufactured with precise dimensional and geometrical tolerances, ensuring optimal load distribution, reduced noise and vibration, and more accurate preload settings. - Rigid bearing application
AMIGO Single row tapered roller bearings are typically adjusted against a second bearing. Applying preload achieves a rigid bearing application.
Running-in period with reduced temperature peaks
AMIGO bearings have a running-in period with reduced friction, heat, and wear, minimizing temperature spikes when mounted and lubricated correctly. - Separable and interchangeable
In AMIGO bearings, the inner ring with roller and cage assembly (cone) can be mounted separately from the outer ring (cup), and the separable components are interchangeable, facilitating mounting, dismounting, and maintenance.
AMIGO Single row tapered roller bearings with machined rings 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:
- Automotive Industry
- Aerospace Industry
- Agricultural Machinery
- Industrial Machinery
