Installation of rolling mill bearings

Installation of rolling mill bearings The service life of rolling mill bearings is not only related to the quality of the bearing, but also closely related to its installation and use. To this end, attention should be paid to the technical requirements for bearing installation, and the relevant operating procedures should be followed. 1. Preparation […]

Bearing selection method

The market requirements for various mechanical devices and instruments using rolling bearings have become increasingly stringent, and the conditions and performance required for bearings have become increasingly diversified. In order to select the most suitable bearing from a large number of structures and sizes, it is necessary to study from various angles. When selecting a […]

Maintenance method of backing bearing

The eighteen-high rolling mill bearings adopt double-row needle roller bearings. When the copper foil is rolled at a high speed of 600m/min, the bearing speed reaches 3550r/min. The working conditions of the bearing are extremely bad, and improper assembly is prone to burns and scratches on the bearing surface. Needle roller fracture, wear, needle roller […]

Analysis and Prevention of Burning Loss of Rolling Mill Bearings

Rolling mill bearings occupies a relatively important position in my country’s rolling mills. Rolling mill bearings often cause mechanical burnout in daily production. How to reduce the number of rolling mill bearings burning, improve the level of rolling mill equipment, and increase the operating rate of rolling mills, especially for rolling mill bearings The cause […]

Bearing Manufacturing Technology-Heat Treatment

To meet the bearing performance requirements, heat treatment for the purpose of quenching and hardening is an indispensable process. The energy consumed in the heat treatment process accounts for about 25% of the total energy consumption in the bearing manufacturing process. Therefore, from the perspective of energy saving and environmental protection, the heat treatment in […]

Analysis on the Causes of the Damage of Rolling Mill Bearings

The bearings used in the rolls of short-stress rolling mills are mostly rolling bearings Rolling mill bearing burning refers to the phenomenon that the sliding heat generated by each part of the bearing increases sharply during the operation of the bearing, and plastic deformation causes the parts to stick, and the phenomenon of seizure caused […]

Deep Groove Ball Bearings

The Main Performance of Deep Groove Bearing

The raceways of the inner and outer rings of deep groove ball bearings are all arc-shaped grooves, and the radius of the groove is slightly larger than the radius of the ball. It is mainly used to bear radial load, but also can bear certain axial load. When the radial clearance of the deep groove […]

Causes of Bearing Noise, Detection and Treatment

If the bearing is in a good state of continuous rotation, it will emit a low whining or buzzing sound. If there is a sharp hiss, squeak and other irregular sounds, it often indicates that the bearing is in a poor continuous rotation condition. The sharp squeaking noise may be caused by improper lubrication. Inappropriate […]

The Common Faults and Routine Maintenance of Rolling Mill Bearings

1. Common faults and cause analysis Rolling mill bearings may be damaged due to various reasons during operation, such as improper assembly, poor lubrication, intrusion of moisture and foreign matter, corrosion and overload, etc., may cause premature damage to the bearing. Even if the installation, lubrication and maintenance are normal, after a period of operation, […]

How to ensure the safe operation of single-row ball slewing ring?

Single-row ball slewing ring is one of the important parts of modern machinery and equipment, mainly composed of upper ring, lower ring and full ball. Its running speed is very low, and it is usually used in many mechanical products, for example, it is widely used in rotating equipment such as rotary conveyors, excavators, construction […]
