High-capacity Cylindrical Roller Bearings
Amigo High-capacity Cylindrical Roller Bearings offer a superior load carrying capacity characteristic of full complement bearings, combined with the high-speed capability of caged bearings. Engineered for demanding applications, these bearings are ideal for use in industrial gearboxes, wind turbine gearboxes, and mining equipment, where both performance and reliability are paramount.
- High Load Carrying CapacityThe cage bars are strategically displaced relative to the roller pitch diameter, allowing rollers to be positioned closer together. This configuration permits the inclusion of additional rollers, thereby enhancing the load-carrying capacity.
- High StiffnessThe increased quantity of rollers directly contributes to greater radial stiffness, providing enhanced structural integrity under load.
- High Speed CapabilityThe advanced cage designs are engineered to accommodate high rotational speeds, rapid accelerations, and peak loads, ensuring optimal performance in dynamic conditions.
- Long Service LifeThe application of a black oxide coating on the rings and rollers (designation suffix L4B) significantly extends service life. This coating enhances resistance to smearing damage, improves running-in properties, reduces friction, and optimizes performance under suboptimal lubrication conditions. Additionally, it offers superior chemical resistance against aggressive oil additives and increases corrosion resistance.
High-capacity Cylindrical Roller Bearings are engineered for optimal radial load capacity, widely utilized across numerous technical sectors. Their precision engineering and versatile designs ensure suitability for a broad spectrum of applications, available in an extensive range of configurations, variants, and dimensions. Typical applications include:
- Heavy-duty gearboxes
- Industrial compressors
- Mining equipment
- Wind turbines
- Paper mill machinery
- Steel rolling mills
- Construction machinery
- Electric motors
- Power generation equipment
- Railway axleboxes
