FAG Self-Aligning Ball Bearings have the following main features and uses:
Design Features:
Self-aligning design: FAG self-aligning ball bearings have automatic self-aligning function, which can adapt to slight misalignment between shaft and housing, and reduce friction and wear caused by installation errors or shaft deflection
Low friction: This bearing design has the lowest friction and can maintain low temperature even at high speeds, ensuring long-term stable operation
Double-row design: Usually a double-row design, it can withstand large radial and slight axial loads and is suitable for occasions with severe misalignment
High-precision applications: Suitable for applications that require high precision and low friction, such as calender rollers on paper machines, which can be maintained and replaced without stopping the machine. Heavy machinery: Suitable for heavy machinery and equipment, such as rolling mills, mining machinery, etc., which can withstand heavy loads and impact loads. Industrial equipment: Widely used in various industrial equipment, such as conveyors, agitators, etc., and can maintain stable operation in harsh working environments. Limit speed and load capacity: Although the specific values are not clearly given in the search results, self-aligning ball bearings generally have higher load capacity and lower limit speed.
As a cornerstone of the Schaeffler Group’s bearing technology, FAG Self-Aligning Ball Bearings are engineered to deliver unmatched resilience in applications prone to shaft misalignment, vibration, and harsh operating conditions. Renowned for their ability to compensate for angular misalignment up to 3°, these bearings are indispensable in industries such as mining, agriculture, and paper manufacturing, where equipment reliability and reduced maintenance are paramount. This guide explores FAG’s self-aligning ball bearing portfolio, emphasizing technical excellence, adaptability, and industry-specific innovations to maximize operational uptime.
