Cylindrical Roller Bearings
Cylindrical roller bearings are particularly well suited for machine tool spindles where the bearing arrangement must accommodate heavy radial loads and high speeds while providing a high degree of stiffness. AMIGO super-precision single row cylindrical roller bearings have a higher speed capability than double row bearings while double row bearings are more suitable for heavier loads.
- High speed capability
- High radial load carrying capacity
- High rigidity
- Low friction
- Low cross-sectional height
AMIGO Cylindrical roller bearings 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:
- Electric motors
- Gearboxes
- Machine tools
- Wind turbines
- Conveyors
- Heavy machinery
- Steel mills
- Automotive transmissions
Cylindrical Roller Bearings - Designs and Variants
Single Row Cylindrical Roller Bearings
Single row cylindrical roller bearings are designed for high radial load capacity, available in various designs such as NU, N, NJ, and NUP types. These are suitable for high-speed applications, offering low friction and ease of maintenance.
Double Row Cylindrical Roller Bearings
Double row cylindrical roller bearings are ideal for applications with higher radial loads and lower speed conditions compared to single row bearings. They provide added rigidity and stability in demanding environments.
Hybrid Bearings
ybrid bearings feature ceramic rolling elements combined with steel rings, offering enhanced performance under challenging conditions like high-speed or high-temperature environments. They are also corrosion-resistant and electrically insulating.
