FAG Bearing Inner Ring Fixing Methods
Source: Bearing Network | Date: November 4, 2013
FAG bearings are widely used in industrial applications due to their high precision and durability. They consist of an inner ring, an outer ring, and rolling elements. The inner ring is a critical component that requires proper axial fixation to ensure the bearing operates smoothly and efficiently. There are several common methods for fixing the FAG bearing inner ring, depending on the application requirements and design constraints. One of the most common methods is using a shoulder and interference fit. This method relies on the shoulder of the shaft or housing to provide axial support, while the interference fit ensures a secure connection between the inner ring and the shaft. It is suitable for applications where both ends of the bearing are fixed, offering a compact layout with minimal space requirements. Another popular method involves using a lock nut and a retaining ring. The inner ring is fixed axially by the shoulder and the lock nut, which is often accompanied by a locking washer to prevent loosening. This method is ideal for high-speed and heavy-load applications, as it provides a safe and reliable fix. In some cases, a shaft end retaining ring is used instead. The inner ring is secured by the shoulder and the retaining ring, which is fastened to the shaft using screws. Anti-loose devices should be installed on the screws to prevent accidental dislodgement. This method is particularly useful when the shaft end is not threaded or when there is limited space available. Additionally, a fixing sleeve can be used to clamp the bearing onto the shaft based on the radial dimensions of the inner hole. This method allows for easy installation and removal of the bearing. A similar approach is used with unloading sleeves, which have a special nut for convenient handling. This method is especially suitable for double-row spherical bearings that experience high radial loads but low axial loads. Proper fixing of the FAG bearing inner ring is essential to maintain the integrity of the entire system. Choosing the right method depends on factors such as load type, speed, space constraints, and maintenance accessibility.
