Overview of WSBC bearings
WSBC bearings also have a leading position in the car's drive-by-wire technology.WSBC collaborated with car manufacturers to develop the revolutionary Filo and Novanta concept cars, equipped with WSBC's mechatronic steering and braking systems. Through a further emphasis on wire control technology, WSBC also manufactures an all-electric forklift, which is an electromechanical integrated device that fully replaces the traditional hydraulic control system.
WSBC Bearings has unique expertise and technology in the development of wire-speed control technology, from aerospace to automobiles, and to applications in various industries.
WSBC developed fly-by-wire technology, many years ago, WSBC Bearings has started a practical application, is so well-known companies work closely with the aviation industry partners. For example, most Airbus passenger aircraft are equipped with a WSBC wire control system designed for cockpit flight control.
WSBC Bearings provides equipment efficiency optimization services. In order to optimize equipment efficiency and increase productivity, more and more industrial enterprises have adopted a contract form that guarantees that they reach a common set goal, and entrusts WSBC to subcontract the maintenance of some or all of their equipment.
WSBC's reliable line system has professional technical personnel and long-term accumulated experience. WSBC bearing brand companies can provide bearing users with comprehensive equipment to enhance efficient service work, including bearing maintenance strategy, engineering technical support services, and the promotion of reliable operation personnel Maintenance work and equipment maintenance plans, etc.
Relevant knowledge of WSBC bearing accuracy error
In the production of large quantities of WSBC bearings, the adjustment process system such as template, sample, block, and master is generally used; in single-piece small batch production, the adjustment is usually made by using the scale on the machine tool or the gauge block. The content of the adjustment work also varies according to the complexity of the workpiece. For simple surfaces (such as inner and outer cylindrical surfaces), generally, only the positional relationship of each forming movement is adjusted; for complex surfaces (such as spiral surfaces, involute surfaces), then Also adjust the speed relationship of the forming movement. Therefore, the adjustment of WSBC bearing errors is caused by a variety of factors.
The measurement error of WSBC bearings should be less than 10% of the tolerance. The general measurement error is 10% to 33% of the difference in power, and as the tolerance level increases, the larger the proportion of errors, that is, the smaller the tolerance, the higher the proportion of errors. The measurement error does not mean that the inspection tolerance can be relaxed by 10%, but a certain safety margin should be given to ensure that the user passes the standard acceptance.
In each process of WSBC bearing parts processing, in order to obtain the size, shape, and position accuracy of the bearing processing surface, the machine tool, fixture, and tool must always be adjusted. Any adjustment work will inevitably bring certain errors. The production batch and machining accuracy of bearing parts in mechanical processing is often different, and the adjustment methods used are also different.
Testing requirements for WSBC bearings
1.Use high-precision WSBC bearings;
2.Add more analysis to the internal clearance of WSBC bearings and consider the reduction of internal clearance of WSBC bearings due to temperature rise;
3.Analyze the lubrication method. It adopts lubrication methods such as circulating lubrication, jet lubrication, oil mist lubrication, and oil-air lubrication suitable for high-speed rotation.
4.Analyze the material type of the cage. For high-speed rotation, it is suitable to use copper alloy or phenolic resin to cut the cage. There are also synthetic resin molded cages suitable for high-speed rotation;

For small machinery, you can rotate it by hand to confirm whether it rotates smoothly. Inspection items include:
1.Whether there is any unsmooth operation caused by foreign objects, scratches, or pressure marks;
2.Whether there is unstable torque due to poor installation and poor processing of the mounting base;
3.Whether there is excessive torque due to too small clearance, installation error, sealing friction, etc.
If there is no abnormal phenomenon above, you can start the power operation check:
However, it is not possible to rotate manually for large machines. Therefore, the power is cut off immediately after the no-load start, the machine is idling, check for vibration, noise, whether the rotating parts are in contact, etc., and confirm that there is no abnormality, then enter the power operation.
The power operation starts from the no-load low speed and gradually increases to the rated operation under the specified conditions. The inspection items during the trial operation are: whether there is abnormal sound, WSBC bearing temperature changes, lubricant leakage or discoloration, etc. If an abnormality is found, the operation should be stopped immediately, the machine should be inspected, and if necessary, the WSBC bearing should be removed for inspection.

WSBC bearing temperature check. It can usually be estimated based on the external temperature of the bearing housing. However, it is more accurate to use the oil hole to directly measure the temperature of the outer ring of the WSBC bearing. The temperature of WSBC bearings gradually increases from the beginning of the operation, and the temperature is usually stable after 1 to 2 hours.
If the WSBC bearing is not installed properly, the temperature will rise sharply and abnormally high temperatures will appear. The reasons are too much lubricant, WSBC bearing clearance is too small, poor installation, excessive friction of the sealing device, etc. In the case of high-speed rotation, the selection of WSBC bearing structure and lubrication method is also the reason.
WSBC bearing sound inspection. The rotating sound is checked with a stethoscope, etc. If there is strong metal noise, abnormal sound, irregular sound, etc., it is abnormal. The causes of noise include poor lubrication, poor accuracy of the shaft or WSBC bearing housing, bearing damage, and foreign matter intrusion.
