    Deep groove ball bearings have a simple structure and are easier to achieve higher manufacturing accuracy than other types. Therefore, they are easy to produce in series and have lower manufacturing costs, and they are extremely common. When a larger radial clearance is selected, the axial bearing capacity increases, and the contact angle is zero when bearing pure radial force. When there is an axial force, the contact angle is greater than zero. Generally, stamping wave-shaped cages, car-made solid cages, and sometimes nylon cages are used. In addition to the basic type, deep groove ball bearings have various modified structures, such as: deep groove ball bearings with dust cover; with rubber Deep groove ball bearing with sealing ring; deep groove ball bearing with stop groove; deep groove ball bearing with large load capacity with ball notch; double row deep groove ball bearing. But they all have the following common features:

     1. In terms of structure, each ring of WSBC deep groove ball bearing has a continuous groove raceway with a cross section of about one third of the circumference of the ball. It is mainly used to bear radial load, and can also bear a certain amount Axial load

     2. When the radial clearance of the bearing increases, it has the properties of an angular contact ball bearing and can withstand alternating axial loads in two directions;

     3. Low friction and high speed;

     4. Simple structure, low manufacturing cost, and easy to achieve higher manufacturing accuracy;

     5. Generally, stamped corrugated cages are used. Bearings with an inner diameter greater than 200mm or high-speed running are made of car-made solid cages.WSBC 23022-2CS online, contact us for more details.

Install application maintenance

     Deep groove ball bearings are the most representative rolling bearings with a wide range of uses. It is suitable for high-speed or even extremely high-speed operation, and it is very durable, low maintenance cost, and long operation cycle. However, it requires professional and technical personnel to check and maintain regularly to ensure the safety, reliability, and improve the operation cycle and quality.

1. Assembly of WSBC deep groove ball bearings

     The assembly of deep groove ball bearings requires assemblers to have high professional skills and strictly implement technical requirements and operating procedures during the assembly process.

     The quality of the bearing installation will affect the accuracy, life and performance of the bearing. Therefore, please fully study the installation of the bearing, and the bearing should be installed in accordance with the following operating standards.

     1. Clean the bearing and related parts. (For grease lubricated bearings and oil seals or dust caps on both sides, the seal ring bearing does not need to be cleaned before installation.)

     2. Check the size and finishing of related parts

     3. Installation method The installation of the bearing should be based on the bearing structure, size and the matching nature of the bearing components. The pressure should be directly applied to the end face of the tightly fitted ring, and no pressure can be transmitted through the rolling elements.Wuxi Spark Bearing Co.,Ltd provides WSBC Beaing 23024-2CS of High-quality and competitive, click here to contact us.

WSBC bearing installation generally adopts the following methods:

     Press fit: When the inner ring of the bearing and the shaft are tightly matched, and the outer ring and the bearing seat hole are loosely matched, the bearing can be press-fitted on the shaft with a press, and then the shaft and the bearing are installed in the bearing seat hole. When press-fitting, an assembly sleeve made of soft metal material (copper or mild steel) is cushioned on the end face of the inner ring of the bearing. The outer ring of the bearing is tightly fitted with the hole of the bearing seat. When the inner ring and the shaft are loosely fitted, the bearing can be Press into the bearing seat hole first. At this time, the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole. If the bearing ring is tightly fitted with the shaft and the seat hole, the inner ring and outer ring should be pressed into the shaft and The structure of the seat hole and the assembly sleeve should be able to simultaneously tighten the end faces of the bearing inner ring and outer ring.

     Heating fit: By heating the bearing or bearing seat, the thermal expansion is used to transform the tight fit into the loose fit. It is a commonly used and labor-saving installation method. This method is suitable for the installation of bearings with large interference, before hot assembly Put the bearing or the separable bearing ring into the oil tank and heat it evenly at 80-100℃, then remove it from the oil and install it on the shaft as soon as possible. In order to prevent the inner ring end face and the shaft shoulder from not fitting tightly after cooling, after the bearing is cooled Axial tightening can be carried out again. When the outer ring of the bearing is tightly fitted with the light metal bearing seat, the hot-fitting method of heating the bearing seat can be used to avoid scratches on the mating surface. When heating the bearing with an oil tank, there should be a grid at a certain distance from the bottom of the box, or the bearing should be hung with a hook. The bearing cannot be placed on the bottom of the box to prevent sinking impurities from entering the bearing or uneven heating. There must be a thermometer in the oil tank. Strictly control the oil temperature not to exceed 100°C to prevent the occurrence of tempering effects and reduce the hardness of the ferrule.

     The installation method of the bearing is usually the shaft rotation. Therefore, the inner ring and the shaft are matched as an over-win fit, and the outer ring of the bearing and the bearing chamber are matched as a clearance fit. Check the bearing operation after the bearing is installed, it should be carried out immediately Operational inspection has confirmed whether the installation is normal.

2. Operation and maintenance

     Reliable maintenance work is the main means to ensure the long-term operation of the bearing. When the equipment is running for a period of time, professional and technical personnel should be asked to inspect and maintain the equipment in time, mainly in the following aspects:

        1.Check the operating temperature of the bearing, it is required to be below 65 degrees.

        2. Check the axial movement of the moving parts. It is mainly whether the clearance of the bearing meets the requirements.

        3. Check whether there are pitting, corrosion, pits, cracks and other defects in the raceway inside and outside the bearing.

        4. The lubrication condition of lubricating oil or grease should be replaced or added in time, but not too much.It requires one-third to one-half of the lubricating oil and one-third of the grease.
