Single row deep groove ball bearings FAQS

QWhich mechanical machines are used for thrust spherical roller bearings?

AExcavators, boilers, air preheaters for thermal power plants, etc. are useful. Thrust bearings are divided into thrust ball bearings and thrust roller bearings. Thrust ball bearings are further divided into thrust ball bearings and thrust angular contact ball bearings. The raceway ring with the raceway with the raceway and the ball and cage assembly is called the shaft ring, and the raceway ring that cooperates with the outer casing is called the raceway. The two-way bearing fits the middle ring to the shaft. One-way bearings can withstand one-way axial loads and two-way bearings can withstand two-way axial loads. Spherical bearings on the mounting surface of the race have self-aligning properties that reduce the effects of mounting errors. These bearings are mainly used in automotive steering mechanisms and machine tool spindles. Thrust roller bearings are divided into thrust cylindrical roller bearings, thrust spherical roller bearings, thrust tapered roller bearings, and thrust needle roller bearings. Thrust cylindrical roller bearings are mainly used in oil drilling rigs and iron making steel machinery. Thrust spherical roller bearings These bearings are mainly used in hydroelectric generators, vertical motors, propeller shafts for ships, tower cranes, and extruders.

QWhat are the main uses of thrust tapered roller bearings:

AOne-way: crane hook, oil rig swivel. Two-way: Roller neck. Planar thrust bearings are mainly subjected to axial loads in the assembly and are widely used. Although the thrust bearing installation operation is relatively simple, there are often errors in the actual maintenance, that is, the tight ring and the loose ring of the bearing are not installed correctly, and the bearing is lost, and the journal is quickly worn. The tight ring is mounted on the end face of the stationary part, ie misassembled. The inner ring of the tight ring and the journal are in a transitional fit. When the shaft rotates, the tight ring is driven and friction is generated with the end face of the stationary part. When the axial force (Fx) is applied, the friction torque will be greater than the inner diameter and the resistance torque will be tight. Forced rotation of the ring-to-shaft mating surface exacerbates journal wear.

QHow to help bearing achieve its maximum service life by bearing tool?

AAfter the bearing has been mounted in an application such as a motor connected to a pump, the application should be aligned. If the application is not properly aligned, the misalignment can cause the bearing to suffer additional load, friction and vibration. These can accelerate fatigue and reduce the bearing’s, as well as other machine components, service life. Furthermore, increased vibration and friction can significantly increase energy consumption and the risk of premature failures. Alignment Includes shaft and belt alignment tools and machinery shims. During operation, it is important to regularly inspect the condition of the bearing by performing basic condition monitoring measurements. These regular inspections will allow the detection of potential problems and help to prevent unexpected machine stops. Consequently, the machine maintenance can be planned to suit the production schedule, increasing the plant’s productivity and efficiency.

QHow to replace bearings safely?

AAt some point, the bearing will reach the end of its service life and will have to be replaced. Although the bearing may not be used again, it is extremely important to dismount it correctly so that the service life of the replacement bearing is not compromised. Firstly, the use of proper dismounting methods tools will help prevent damage to other machinecomponents, such as the shaft and housing, which are often re-used. Secondly, incorrect dismounting techniques can be hazardous to maintenance personnel.
