Single row cylindrical roller bearing is a kind of bearing widely used in mechanical equipment. It consists of inner ring, outer ring, cylindrical roller and cage. Its cylindrical rollers are in complete contact with the inner and outer rings, so they can withstand large radial loads.
N series bearings：There are ribs on both sides of the inner ring, and there are no ribs on the outer ring.
NJ series bearings：Have two integral flanges on the outer ring and one on the inner ring.
NU series bearings: Have two integral flanges on the outer ring and no flanges on the inner ring.
NUP type bearings: There are ribs on both sides of the outer ring, a fixed rib on one side of the inner ring, and a detachable flat ring on the other side.
1. Automobile transmission bearings and engine support shaft bearings: Bear various loads during automobile movement and have excellent reliability and durability;
2.Machine tool spindle bearings: Bear large radial load and certain axial load;
3.Heavy machinery bearings: Single row cylindrical roller bearings compared with ball bearings of the same size, the radial load capacity is increased by 1.5-3 times, with good rigidity and impact resistance.
Single row cylindrical roller bearings have one row of rollers and are suitable for applications where radial and axial loads are relatively low. Double row cylindrical roller bearings have two rows and are used in applications where higher loads are expected or where higher levels of reliability are required.
Steel retainer: High strength, light material;
Brass cage: It has high tensile strength, but relatively low density and high limit speed;
Polyamide (nylon) cage: The advantages of high elasticity and light weight make this cage have very good sliding and self-lubricating properties.
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.
