Flange slewing bearings are a specially designed slewing bearing, the main feature of which is that there are flanges on one or both sides of the inner and outer rings, which makes the installation and fixation of the bearings easier and more secure. They are called "machine joints" in various industrial applications because they can simultaneously withstand axial force, radial force and overturning moment, and achieve relative rotational motion.
Installed on both sides of the bearing end face to prevent dust, moisture and other impurities from entering the interior. At the same time, it prevents grease leakage and increases service life. The bearing is equipped with a lubrication hole or a grease nipple for easy regular maintenance. Some models are equipped with pre-filled grease or automatic lubrication device.
Used to evenly separate rolling elements and ensure smooth operation. Common materials include steel, brass or engineered plastics.
Can be steel balls or rollers, placed in the raceway between the inner and outer rings. Enables low-friction rotation while transmitting loads.
Two concentric steel rings, usually with a flange structure on one side. The flange design can be selected between inner ring flange type or outer ring flange type, depending on the installation method. Bolt holes are reserved on the flange for quick installation and fixing.
Precision raceway machining and high-quality rolling elements ensure smooth bearing rotation and lower friction, thereby improving mechanical performance and reducing wear.
In order to achieve a simple drive solution, flange slewing bearings can provide a variety of gear configurations such as no gear, external gear or internal gear to adapt to different transmission requirements.
The raceway of the flange slewing bearing is usually heat treated by induction hardening, with a hardness of HRC55-62, ensuring its effective hardening depth, improving wear resistance and service life. The high stiffness also makes it suitable for occasions that require bearing application stiffness.
Due to the integrated design of the flange, additional bearing seats can be omitted, making the entire structure more compact and possibly reducing the overall weight. This provides great advantages for some mechanical equipment with strict space and weight restrictions.
Flange type slewing bearings usually use balls or rollers as rolling elements and are specially designed and heat treated to withstand various complex combined loads, including axial, radial and overturning moment loads. Some designs, such as four-point contact ball or cross roller, can provide higher load capacity and rigidity.
This is the most significant feature of flanged slewing bearings. The flange is usually located on the outer ring, which can provide a direct mounting surface, simplify the design and installation process of the bearing seat, make axial positioning simple, and help prevent axial movement of the bearing when subjected to thrust loads or strong vibrations.
