Installation Method and Usage Precautions of Super-precision single row cylindrical roller bearing :   

Super-precision single row cylindrical roller bearings are a type of high-precision bearings that are designed to operate at extremely low levels of friction and provide exceptional accuracy and reliability in demanding applications. These bearings are commonly used in machine tools, automotive assemblies, and other precision equipment where high levels of precision and performance are required.

A super-precision single row cylindrical roller bearing consists of an inner and outer ring, cylindrical rollers, and a cage or retainer that holds the rollers in place. The cylindrical rollers are arranged in a single row between the inner and outer rings, allowing for high radial load capacity and excellent rigidity. This design also allows for high-speed operation and low heat generation, making these bearings ideal for high-speed and high-temperature applications.

One of the key features of super-precision single row cylindrical roller bearings is their high level of precision and accuracy. These bearings are manufactured to very tight tolerances, ensuring that they can operate with minimal runout and vibration. This precision is achieved through advanced manufacturing techniques, including precision grinding and super-finishing of the bearing surfaces.

In addition to their high precision, super-precision single row cylindrical roller bearings also offer excellent load-carrying capacity and rigidity. The cylindrical rollers in these bearings are designed to distribute the load evenly across the bearing surface, allowing for high radial load capacity and resistance to deformation under load. This ensures that the bearing can withstand the high forces and pressures typically encountered in precision applications.

Another important feature of super-precision single row cylindrical roller bearings is their low friction and heat generation. The design of these bearings minimizes contact between the rolling elements and the raceways, reducing friction and heat buildup during operation. This not only improves the efficiency of the bearing but also extends its service life by reducing wear and tear on the components.

super-precision single row cylindrical roller bearings are a versatile and reliable choice for a wide range of precision applications. Their high precision, load-carrying capacity, and low friction make them ideal for use in machine tools, robotics, automotive assemblies, and other high-precision equipment. By choosing a super-precision cylindrical roller bearing, engineers and designers can ensure that their equipment operates with the highest levels of accuracy and performance.

 N 1011 KPHA/SPVR592 bearing precautions and installation methods

Compared with general mechanical parts, bearings have very high manufacturing precision and have certain requirements for installation and use. If you do not pay great attention, it will cause damage to the bearings, and the normal service life of the bearings will not be obtained, and it will also cause damage to related parts. of damage. Generally speaking, accidents caused by bearings are caused by improper installation and irregular use. Therefore, if they can be installed and used in the correct way, the service life of the bearings can be improved.

1.N 1011 KPHA/SPVR592Things to pay attention to when working

When installing bearings, the most important thing is to keep the bearings and related parts clean and to use installation tools and methods correctly. Therefore, it is important to observe the following precautions:

1. Clean the working area and use clean tools or auxiliary tools for work.

2. When installing, you should use auxiliary tools with good plasticity and not easy to fall off.

3. Confirm that all assembled parts are qualified.

4. The bearing cannot be unsealed until it is used.

5. Keep the bearings clean during operation.

6. Under normal circumstances, the anti-rust oil does not need to be washed away. It can be installed in its original state. If it is necessary to install lubricating grease, use gasoline to clean the grease on the bearing, and then blow it clean with an air gun.

2.N 1011 KPHA/SPVR592Bearing installation - inspection work before installation

Things to note before installing bearings:

1. Are the dimensions of the shaft and bearing body processed according to the drawing requirements? Are there any protrusions at the corners and right angles of the shaft, bearing body, and can they fully contact the end face of the bearing? All must be fully inspected.

2. It should be determined whether there are bruises, bulges, etc. on the mating surfaces of the shaft and bearing body. There is dust or molding sand attached to the surface of the bearing shell. If there is, use a whetstone, fine sandpaper or a clean rag to remove it.

3. In order to avoid bruises during installation, a small amount of lubricating oil should be applied to the working surfaces of the shaft and bearing body.

4. Bearing installation - force application surface and force application method. When the bearing is installed on the shaft, force must be applied on the inner ring. When installed on the bearing body, force must be applied on the outer ring. Note: Do not knock the outer ring when the bearing is installed on the shaft. Do not knock the inner ring when it is installed on the bearing body. Such operations will inevitably cause scratches on the bearing track surface, causing noise and early termination of failure, affecting the bearing life. When applying force to the bearing, be sure to make the force vertical and even downwards. If the force is applied off-center, the bearing will be damaged. Therefore, definitely avoid missing shots. In addition, do not apply force to the bearing cage and sealing plate.

5. Installation of bearings - Installation using a hammer and casing. The installation method of using a hammer and casing is a commonly used method. It must be as shown in the picture, so that the sleeve is in the middle and knocked in. The hammer should be tapped gently. .

6.Bearing installation - When the inner and outer rings are installed at the same time, in terms of the mechanical structure, when the inner and outer rings are tightly fitted, a backing plate should be used, and the force must be applied to the inner and outer rings at the same time to knock them in. If external force is applied only to the inner ring, the force will be pressed into the outer ring through the balls, thus causing scratches on the track surface.

7.Assembly summary of rolling bearings a. All dirt on the bearings must be cleaned before assembly. b. When installing the bearing on the shaft, the pressure of pressing the bearing should be on the inner ring. When installing the bearing into the bearing body or suspension (bracket), the pressure should be applied on the outer ring. c. When pressing or driving in with a copper rod, the pressing force and impact force should be evenly distributed on the entire end surface of the inner and outer rings of the bearing, and no force should be applied to the cage or beads. At the same time, The hammer should not be used to directly hit the bearing end face to avoid bruising or damaging the bearing. [The auxiliary tools used for cold installation and hydraulic installation are casing and hydraulic equipment respectively]. d. When installing bearings, attention must be paid to the surrounding environment to prevent dust and dirt from entering the bearings. After installing the bearing, the installed bearing should be protected (sealed) immediately. e. After the bearing is tightened, the rotational flexibility of the rolling bearing must be checked. f. Although the fit between the rolling bearing and the shaft or bearing seat is an interference or transition fit, considering the structure and bonding strength of the parts, heating or cooling methods must be used for assembly. Generally (SKF) heating should not exceed 110°C.
