The characteristics of spherical bearings with seats
1. Equipped with automatic heart adjustment function
The outer diameter of the bearing and the inner diameter of the bearing seat are spherical in fit, and there is an automatic centering function between the two, which can compensate for the misalignment of the axis caused by installation errors and the deformation of the installation bottom surface.
2. High load capacity
Due to the same internal structure as the 6200 and 6300 series deep groove ball bearings, FS seated outer spherical ball bearings can not only withstand radial loads but also certain axial loads. At the same time, the working noise of the bearings is low.
3. Long service life
Spherical ball bearings with seats are usually used in harsh working environments such as soil, dust, humidity, and high temperatures, and the lubricating grease inside the bearing will deteriorate in a short period of time. Therefore, it is necessary to regress the outer spherical ball bearings with seats at appropriate time intervals and replace the deteriorated grease with fresh grease. FS cast iron outer spherical ball bearings are equipped with oil nozzles that can be re lubricated, ensuring perfect performance and long service life in any working environment.
Lubricating grease can be selected according to the different ambient temperatures used. Normal temperature, low temperature, and high temperature lubricating grease can be used. The outer ring of the bearing has an oil groove, which can better ensure that the lubricating grease can be smoothly injected into the bearing through the oil nozzle.
4. Excellent sealing performance
The outer spherical ball bearing is equipped with a combination of heat-resistant and oil resistant rubber sealing rings and steel plate dust covers on both sides. The dust cover is assembled on the outer diameter of the bearing inner ring and rotates together with the inner ring, which can effectively prevent external foreign objects from entering the inside of the bearing and resist external pressure to protect the bearing. This combination seal composed of a sealing ring and a dust cover can prevent soil, dust, and moisture from entering the inside of the bearing, and also prevent the leakage of lubricating grease inside the bearing. Enable bearings to maintain perfect performance even in harsh working environments.
5. Sturdy bearing seat
The bearing seat is an integral seat structure with excellent rigidity, preventing deformation of the bearing during assembly. The bearing seat is durable and long-lasting under any working condition. The bearing seat can be cast from materials such as gray cast iron, ductile iron, and cast steel.
6. The bearing can be easily locked onto the shaft
There are four ways to lock the bearing on the shaft, and the commonly used method is to lock two set screws on the extended end of the inner ring, or use a set sleeve, locking sleeve, or eccentric sleeve for locking. These four methods can easily lock the bearing onto the shaft.
7. Special heat treatment of bearing inner ring
The inner groove and its surrounding parts that need to be hardened are quenched normally, and the extended end of the inner ring for assembling the set screw is tempered locally at high temperature to maintain toughness and impact resistance. After local high-temperature tempering around the inner ring screw hole, the bearing achieves better performance, which can prevent the screw from loosening during bearing operation. At the same time, tightening the screw tightly will not cause the inner ring to burst.
8. Unique design to prevent outer ring rotation
The outer ring of the bearing is equipped with a unique stop ball, which allows the bearing to automatically adjust its center and prevents the outer ring from rotating, resulting in a longer service life of the bearing.
9. Bearings and bearing seats can be completely interchangeable
The bearings and bearing seats have undergone precision machining, and the bearings and bearing seats can be completely interchangeable, making it easy to replace the bearings at any time.
10. Easy to install
The outer spherical ball bearing has been pre injected with sufficient high-quality lubricating grease, and can be directly installed on the shaft with a seat. Therefore, it can prevent harmful substances from entering during the installation of bearing units
