Because full complement cylindrical roller bearings can be used in a lot of heavy machinery and equipment, their most important features are the following three points:
Strong load-carrying capacity: full complement cylindrical roller bearings have a large number of rollers inside and accordingly have a strong load-carrying capacity, which is suitable for high load-bearing occasions.
Good fatigue resistance and durability: full complement cylindrical roller bearings have multiple long rollers inside and are in 90-degree contact with the shaft diameter, which can greatly improve the fatigue resistance and durability of the bearings.
Wide applicability: suitable for higher running speeds and loads, it can be used in a variety of industries and equipment.
Full complement cylindrical roller bearings can be used in many heavy machinery and equipment, such as metallurgical equipment, mining equipment, ships, generators, petroleum machinery, iron and steel machinery and so on.
Among them, metallurgical equipment application full complement cylindrical roller bearings can carry heavier loads under harsh environments, high thermal loads, working parts are affected by inertial forces and shock loads, the torsional stiffness and durability of bearings are reduced;
Mining equipment is also one of the main application areas for full complement cylindrical roller bearings, which can withstand greater load capacity under tensile and compressive loads while maintaining sufficient stiffness at low speeds and relatively long bearing life.
Full complement cylindrical roller bearings have two inner rings, which are coupled together by a clamping ring and cannot be separated, and an outer ring with a centre retaining edge, which can withstand bi-directional axial loads and be used as locating bearings. Due to the large distance between the two rows of rollers, they can also withstand tilting moments. There are two stop grooves on the surface of the outer ring, which can be axially located.
Roller bearings are mainly spherical roller bearings, thrust spherical roller bearings, tapered roller and cylindrical roller bearings and other structural types.
QJ218-N2-MA belongs to a four-point contact ball bearing. It has an inner diameter of 90mm, an outer diameter of 160mm, a thickness of 30mm, a single-row bearing with locating grooves, a solid brass cage and an outer ring guide.
There are countless brands of linear motions, and it is often difficult to choose when purchasing. Today we will take stock of the characteristics of the world's 10 ten linear motion brands. Understanding these brands will help you make targeted choices.
Bearings, as one of the key components of mechanical equipment, their normal operation is critical to the performance and life of the equipment. However, when abnormal sounds occur in bearings, it often signals potential problems and failures. In this essay, we will discuss in depth the causes, effects and coping strategies of abnormal bearing sounds.
Our Shandong Tefule Bearing Factory is located in the Bearing Industry Base of Liaocheng, Shandong Province. It is committed to the production and creation of automotive bearings and agricultural machinery bearings.
The ABEC grading system uses odd numbers - 1, 3, 5, 7, and 9 - as classification levels. The five different grades are listed in descending order of tolerance.
Automotive bearings, as critical components, play an integral role in the performance and reliability of vehicles.
Different choices of bearing materials will bring different performances to the bearing itself. Please follow us below to learn about the material knowledge of bearings and explore their different properties and applications.
Ball bearings can make the machine run more smoothly, reduce energy loss, and extend the service life of the machine. The application range of bearings is extensive, covering almost all fields of machinery and equipment in daily life.
