We are Ningbo Kent Bearing, one of the leading high-quality bearing manufacturer and supplier, established in 2003. Specializing in the production of medium and high-end silent bearings
"Manager Zhang of a motor factory in Zhejiang Province was just scolded by a customer. The new household air conditioner motor made a tractor-like noise in three months. The bearings of two suppliers were not solved. After two reworks, the customer's order was about to be cancelled..." After changing to Kent, there was no rework in three years, and the maintenance cost was cut in half. Replacing a bearing = replacing the bombardment of after-sales phone calls, replacing the anxiety of backlog of work orders, and replacing the risk of customer loss. Seeing this, have the bosses and engineers of the motor factory also encountered similar problems? Ordinary bearings are deformed, noisy, and can't go up to speed after being used for a long time, causing you to be complained by customers and half of your profits are swallowed up by after-sales maintenance?
Many bearings on the market have the shortcomings of insufficient precision: the inner and outer rings have large tolerances, the vibration exceeds the standard when the motor is installed, the bearing seat wears quickly, and the life span does not last more than half a year. Cutting corners on materials: using ordinary steel, metal fatigue under high temperature and high speed, directly stuck. Lubrication technology is old-fashioned: grease is lost at high temperature, the abnormal noise becomes louder and louder, and customers shake their heads when they hear it.
Kent bearings' solution is 0.002mm ultra-precision machining, with a vibration value 30% lower than the national standard. High-speed motors (above 10,000r/min) can run for 3 years without shaking or making noise. Vacuum degassed bearing steel + special heat treatment, temperature resistance of 160°C, impact strength increased by 50%, and variable frequency motors are not afraid of using them. Fully enclosed polymer self-lubricating technology, the grease will not dry up for 10 years, and the silent effect makes home appliance customers actively repurchase.

The installation force required to install precision bearings or annular workpieces tends to increase rapidly as the bearing size increases. Because of the installation force requirements, larger precision bearings are difficult to push onto the shaft or into the bearing seat. Especially when the inner diameter of the precision bearing is greater than 70mm or the interference fit is large, the precision bearing, bearing seat and annular workpiece need to be heated before installation. Using the principle of thermal expansion and contraction, the heating method is used to expand the precision bearing hole. This not only saves effort and time during installation, but also avoids damage caused by excessive force. Under normal circumstances, when using oil bath heating or electric induction heating methods, the heating temperature of standard bearings should not be higher than 100℃, and that of high-speed bearings should not be higher than 150℃.
1. Electric heating plate heating method
Put the precision bearing on a hot plate at a temperature of 100℃ for a few minutes. This method is relatively simple. Flipping it several times can make the precision bearing heat evenly and at the same time have high efficiency. This method can also be used for large and small joint bearings.
2. Electric furnace heating method
Place the precision bearing in a closed automatic temperature-controlled electric furnace for heating. This method heats evenly, controls the temperature accurately, and heats quickly. It is suitable for heating more precision bearings at one time.
3. Induction heating methodmatch uses an induction heater to quickly, stably and neatly heat the joint bearing to the required temperature. It is especially suitable for situations where the inner ring is tightly fitted, because only the inner ring is heated, and the outer ring is not heated enough. In this way, it can be installed on the shaft and easily installed in the seat hole.
4. Light bulb heating methodmatch uses a 50W light bulb to heat the bearing, which can ensure that the heating temperature is around 100℃. Smaller precision bearings can be placed directly on the bulb, and larger precision bearings can be placed in the conical cover of the bulb. The conical cover can also prevent the heat loss of the bulb. At the same time, the heating is uniform and the conical cover can be adjusted up and down.
This method can be adapted to heating precision bearings of different sizes within a certain range. If a far-infrared bulb is used, it is also necessary to pay attention to the direction of the bulb should be downward to prevent infrared rays from affecting the human eye. The bulb heating method is suitable for occasions where the bearing needs to be heated infrequently and in small quantities. The bulb can also be used as a lighting device on weekdays. No other equipment is required.

In order to help motor manufacturers maximize the efficiency of bearing applications, Kent Bearings has built a closed-loop support from design and development to after-sales guarantee through full-process technical collaboration and agile service system, providing systematic solutions for motor customers.
Kent Bearings has been working closely with motor manufacturers since the early product development stage. The bearing technology team has a deep understanding of the design requirements, operating conditions and performance goals of the motor. Combined with its own professional knowledge, it provides bearing selection suggestions for motor design, optimizes the bearing installation structure, ensures the perfect match between the bearing and the motor, and reduces the probability of bearing problems from the source.
During the motor production process, if there are problems with the motor bearings, Kent Bearings provides on-site technical support services. Professional engineers are dispatched to assist motor manufacturers in bearing installation guidance to ensure that the installation process meets standard requirements. At the same time, the motor bearings on the motor production line are randomly inspected to strictly control product quality and avoid affecting the overall performance of the motor due to motor bearing quality problems. When the motor manufacturer's customers report that the bearing is faulty, the rapid response mechanism is immediately activated. After receiving the notification, the after-sales service team of Kent Bearings will communicate with the customer as soon as possible to understand the fault phenomenon in detail and arrive at the site in the shortest time. We use professional testing equipment and rich experience to diagnose and analyze bearing failures and develop solutions. If bearings need to be replaced, we ensure that high-quality replacement products are provided quickly and that subsequent use is tracked to ensure that the problem is completely resolved.
If you have any questions about the use of your motor bearings, please contact Kent Bearing to provide you with well-made motor bearings, one-stop and worry-free after-sales service.
