Plane Thrust Ball Bearing is a type of high-performance bearing designed to carry thrust loads at high speeds. This type of bearing comprises two grooved raceways, with a series of balls positioned in between them.
The unique design of Plane Thrust Ball Bearings allows for the transmission of axial loads in one direction only, making them suitable for applications where high precision and resilient axial load carrying capacity is required. These bearings are commonly used in various industrial applications, including heavy machinery, automobile transmissions, and aerospace engineering.
Plane Thrust Ball Bearings are available in various sizes and designs, including single and double direction designs, and can be made from a range of materials to suit specific application requirements. In summary, Plane Thrust Ball Bearings provide high efficiency, precise axial load carrying capacity, and durability for demanding industrial applications.
There are many causes of bearing damage, such as improper installation, dirt intrusion or moisture intrusion, which are the common causes of early damage of many planar thrust ball bearings.
Analysis of common damage causes of bearings and corresponding preventive measures that can prolong the service life of bearings.Improvement Measures to Prevent Damage of Plane Thrust Ball Bearing
Improper operation: improper installation, operation or disassembly may cause deformation or damage to the cage
Insufficient lubrication: insufficient or improper lubrication may lead to component scratch or serious bearing deformation
Rust and corrosion: contact with water may cause corrosion and rust of plane thrust ball bearing elements. Rusted and damaged bearings may cause spalling during operation
Current: energizing the bearing while rotating may cause grooves or nicks. When the bearing is stationary, improper grounding of electrical operation will cause slight burns
External materials: abrasive particle contamination and debris intrusion may cause wear, scratches and dents on the working surface of planar thrust ball bearings
Eccentricity: eccentricity, inclination or excessive load may lead to geometric stress concentration or surface spalling
Troubleshooting. Replace the front plane thrust ball bearing and grease, and adjust the bearing clearance. The axial clearance is 0.003mm and the radial clearance is 0.002mm;
Self made simple grinding tool, manually grind the positioning surface of the inner conical hole of the bearing, and check with the coloring method to ensure that the contact area between the tool handle and the bearing centering conical hole is greater than 85%; Replace the Belleville spring.

Install the repaired bearing back into the bearing housing and check the radial runout with a dial indicator. It is less than 0.006mm at the proximal end and less than 0.010mm at 150mm at the distal end.
During the trial processing, the temperature rise and noise of the bearing are normal, the processing accuracy meets the processing process requirements, and the fault is eliminated.Improvement Measures to Prevent Damage of Plane Thrust Ball Bearing

① Add compressed air fine filtration and drying devices. The filter shall be drained regularly, and the filter element shall be cleaned or replaced regularly;
② Check the cleaning and matching condition of the taper hole and knife handle of the plane thrust ball bearing at any time, and check whether the air dryer works normally;
③ Reasonably arrange the processing technology to avoid the sudden change of material removal rate;Improvement Measures to Prevent Damage of Plane Thrust Ball Bearing
④ Overload operation is strictly prohibited. In case of failure, it shall be reported for repair in time. It is not allowed to operate with disease.
Bearing maintenance is a necessary condition for the operation of ina combined needle roller bearing. The common maintenance is for the lubrication of bearing. After reading how to select the lubrication mode of bearing and understanding the lubrication mode of bearing, it is also necessary to understand the maintenance of bearing system. Let’s see how to carry out bearing lubrication and maintenance.
1、 The use and installation shall be careful, and strong stamping is not allowed. The solution to the bad phenomenon of ina combined needle roller bearing is not allowed to directly knock the bearing with a hammer, and the pressure is not allowed to be transmitted through the rolling body.Improvement Measures to Prevent Damage of Plane Thrust Ball Bearing
2、 Use proper and accurate installation tools, try to use special tools, and try to avoid using cloth and short fiber.Improvement Measures to Prevent Damage of Plane Thrust Ball Bearing
3、 Keep ina combined needle roller bearing and its surrounding environment as clean as possible. Sodium base grease is generally used for motor bearing. Even if the invisible smile dust enters the bearing, it will increase the wear, vibration and noise of the bearing.
4、 To prevent the corrosion of ina combined needle roller bearing, when taking the bearing directly by hand, fully wash the sweat from your hands and apply high-quality mineral oil before operation. Pay special attention to rust prevention in rainy season and summer. Under some special operating conditions, ina combined needle roller bearing can obtain a longer life than the traditional calculation, especially under light load. The damage mechanism of the labyrinth bearing and the seal surface of the rolling bearing may be limited by these factors.Improvement Measures to Prevent Damage of Plane Thrust Ball Bearing
Lubricants are important not only for bearings, but also for all bearings. However, please note that ina combined needle roller bearing should not add too much grease. Then it’s time to change the lubricant of the bearing.
After draining the old engine oil, if possible, the bearings lubricated with engine oil should be filled with fresh engine oil and let the machine rotate at low speed for a few minutes. Improvement Measures to Prevent Damage of Plane Thrust Ball Bearing
Make the oil collect residual pollutants as much as possible, and then drain the oil. When replacing the grease of the bearing lubricated with grease, the Joe remover used shall avoid the contact of cotton with any part of the bearing. Because these residual fibers may wedge between rolling parts and cause damage, especially in bearing applications.Improvement Measures to Prevent Damage of Plane Thrust Ball Bearing
