Try to use special tools, and try to avoid using cloth

Precautions for Use Hardchn Roller Bearings are precision parts, so they are required to be cautious when using them. The heavier load uses a larger amount of over gain, and the lighter load uses a smaller amount of over gain. Therefore, the use of Hardchn roller bearings should pay attention to the following:

Keep Hardchn roller bearings and the surrounding environment clean. Even if high-performance Hardchn Roller Bearings are used, if they are used improperly, the expected performance will not be achieved. Care must be taken when using and installing, strong punching is not allowed, direct hitting of Hardchn roller bearings with a hammer, and pressure transmission through rolling elements are not allowed.

The tightness of the inner Mechanical Bearing 6300 and shaft, outer ring and seat hole of Hardchn roller bearings is only It can be achieved by controlling the tolerance of the journal and the tolerance of the seat hole. Use appropriate and accurate installation tools, try to use special tools, and try to avoid using cloth and short fibers. Hardchn roller bearing inner ring and shaft are matched with base hole system, Hardchn roller bearing outer ring and seat hole are matched with machine shaft system..

To prevent the corrosion of Hardchn roller bearings, when picking Hardchn roller bearings directly with your hands, you must fully wash away the sweat from your hands and apply high-quality mineral oil before operating. Therefore, in most cases, the choice is based on the use of fine research. Load size The amount of over gain between the ring and the shaft or housing depends on the size of the load. Even if the invisible smile dust enters the Hardchn roller bearing, it will increase the wear, vibration and noise of the Hardchn roller bearing

Self-sealing compact hydraulic sealing ring

When the hydraulic cylinder is Mechanical Bearing 608, the pressure liquid squeezes and stretches its sealing lip to make it close to the sealing surface to produce a higher additional contact stress that increases with the pressure of the pressure liquid, and together with the initial contact stress to prevent the pressure Leakage of liquid. They have the advantages of simple structure, easy manufacture and low cost, so they are widely used in hydraulic transmission systems. Additional contact stress, and together with the initial contact stress to prevent the leakage of pressure liquid. 3: Stefan Steer seal is usually composed of a synthetic rubber o-shaped sealing ring and a special shape rectangular-trapezoidal sealing ring filled with polytetrafluoroethylene.

Self-sealing compact hydraulic sealing ring: Lip-shaped sealing ring, the contact area of ​​the lip that closely fits the sealing surface is small, which can produce greater compression deformation and obtain better sealing effect.   When the hydraulic cylinder is working, the pressure liquid squeezes the self-sealing compression type hydraulic seal to further deform it and produce a greater pressure of the pressure liquid on the sealing surface, which should be strictly the pressure.

YX-shaped sealing ring YX-shaped sealing ring is a Y-shaped sealing ring whose cross-sectional height to width ratio is greater than 2 and the working lip is not equal to the non-working lip. Y-shaped sealing ring The Y-shaped sealing ring maintains the seal by relying on its open lip close to the sealing surface. The Rugular circle and the Steroid circle and so on. It can usually be used alone. Therefore, the Y-shaped sealing ring is suitable for hydraulic cylinders with high-speed variable pressure, large cylinder diameter and large stroke. Therefore, the U-shaped sealing ring is only suitable for hydraulic cylinders with low working pressure or low moving speed. It is divided into a YX-shaped sealing ring for holes and a YX-shaped sealing ring for shafts.

The friction resistance is relatively large and increases with the increase of working pressure and the number of sealing rings. If the O-shaped sealing ring is used in combination with it, that is, when the seal is combined, even after the lip is worn, the synthetic rubber O-shaped sealing ring has greater elasticity.

Various cage materials have certain requirements for temperature

6.Although the bearing is composed of many parts, the cage can also be said to be a blood vessel miniature deep groove ball bearings factory of the bearing. The following are the advantages and disadvantages of using different types of bearing cages introduced by China Bearing Network. Impact load of bearings. may damage the bearing or the cage. The cleanliness of the bearing. 2. The label of the lubricating oil or grease is incorrect.

Error in selecting material for bearing cage. Therefore, in the performance of the bearing, the quality of the cage is directly related to the efficiency of the bearing. If the coupling is misaligned, the bearing is skewed and the force is uneven; the belt is installed too tight; environmental problems, etc. Insufficient bearing lubrication. The disadvantage is that the operating temperature should be used below 120 degrees Celsius. 3. If the material selection is not correct, it is also the cause of damage to the cage. Various cage materials have certain requirements for temperature resistance and rotation speed. 4. Installation problems. The intense vibration in the impact load produces the impact of the rolling body on the cage.

If the bearing is installed incorrectly, the cage will be damaged during installation. According to the summary, Zhonghua Bearing Network will share it below. What is a bearing cage? A bearing cage (also called a bearing retainer) refers to a bearing part that partially encloses all or part of the rolling elements and moves with it to isolate the rolling elements, and usually also guides the rolling elements and keeps them in the bearings.

The cage separates the rolling elements at equal distances and is evenly distributed on the circumference of the raceway to prevent collision and friction between the rolling elements during work; 2. Below are the main types of bearing cages, the main effects of cages on bearings, and the reasons for cage damage. The main types of bearing cages are mainly divided into three types: nylon cages, window-type stamped steel cages and window-type brass cages. Guide and drive the rolling elements in the correct Rolling on the raceway; 3..
