IKO needle roller bearing manufacturer body is slender needle roller bearings for rotation

IKO needle bearing its special internal structure of the mechanical design of small, lightweight. Guide bearings needle roller bearings are given high-quality, unique mechanical equipment to do precision machining, with the latest machines for quality evaluation, product maintain a high performance and high quality standards.
IKO needle roller bearing manufacturer body is slender needle roller bearings for rotation. Compared with ball bearing, needle roller bearings have a low profile and high load capacity characteristics. The use of needle roller bearings for mechanical simplicity of the whole space-saving and other aspects contribute. Widely used in machine tools, automobiles, motorcycles, printing machinery, industrial robots and construction equipment industries.

precision bearings requirements

Since the accuracy of precision bearing itself in less than 1μm, thus requiring its mating parts (shafts, bearing housings, end caps, ring, etc.) have a high dimensional accuracy and shape accuracy, especially with the surface to control the accuracy and bearing the same level, and this is a crucial point, but also the most easily overlooked.
Must also pay attention to match the mechanical precision bearing manufacturer  it is not the above requirements, often makes precision bearings in the bearing after installation error occurs several times larger than the original, or even 10 times more errors, fully become a precision bearings, because the match machine the error components are often not simply added to the error of the bearing, but on multiple amplified with different additions.

The difference between precision bearings and plain bearings

precision bearing and plain bearings should distinguish between the following points:
1, the value is not the same size requirements, high level of accuracy of the product of its size deviation (inner diameter, outer diameter, oval, etc.) than the required accuracy level low product value is smaller;
2, the rotation accuracy required value is not the same, high level of accuracy of the product of its rotational accuracy (internal radial runout, diameter runout, the end face of the raceway beating) the lower level of precision than the value of the product requirements to bearing manufacturers;
3, the surface shape and surface quality requirement value is not the same, high level of accuracy of the products in which the surface shape and surface quality (or channel raceway surface roughness deviation from circular, groove-shaped deviation) than the low level of precision the value to be strict product requirements;
4, precision grade products which are particularly high accuracy grade material than the average material properties of the product is more favorable.
Under normal circumstances, the accuracy of the finished grade rolling into the following six levels (from low to high): 0; 6; 6X; 5; 4; 2

Ideal sleeve bearing materials

Between bearing and shaft neck part of the load is transmitted through direct contact between the sliding surface, which is the boundary lubrication state. So the friction, wear and heat is inevitable. How to choose the sliding bearing materials to compensate for the lack of lubrication condition,roughness measuring instrument ,it is particularly important, according to the working characteristics of sliding bearing, sliding bearing materials should have the following properties of the ideal . (1) to reduce friction, material has the property of low friction resistance, associated with the shaft material and lubricant. bearing cage (2) the ability of wear resistance, abrasion resistance of the materials, and the microstructure of the material, the yield strength and hardness.

Mechanical spindle maintenance

mechanical spindle maintenance
Lowering the operating temperature of the bearing, the lubricating oil is often used approach. There lubrication, oil lubrication, oil circulation lubrication two kinds. When using these two methods to note the following:
1, in the use of oil circulating lubrication, to ensure that the fuel tank thermostat spindle fully adequate.
2, oil lubrication and oil circulation lubrication just the opposite, it can be when the bearing space per cent as long as the filling capacity.
Advantages of circulating lubrication is grinding spindle, in the case meet the lubrication, to reduce friction and heat, but also be able to give some of the heat absorbed by the spindle assembly.
For the same spindle lubrication in two-drop: Oil mist lubrication and injection lubrication.

rigidity and emergency response

Chiesa Corse racing team designed and manufactured by the company  Cardin axle unit and cylindrical roller bearings engine solutions for Chiesa Corse racing team provides the best speed , rigidity and emergency response , and to ensure that the car high-speed rotation efficiency and long reliable service life , thus engine bearings for high performance racing gives more adequate power , rigidity and reliability. Here are  Roller Bearings‍  distributor in China 's detailed report.

 solutions for racing system , which is the unit of  racing in karts Chiesa Corse racing team provides customized technology solutions, primarily for racing wheel bearing applications and engines were designed . The device uses the car dust cover unit that allows its bearings under race conditions convenient for cleaning lubrication, thus ensuring the efficiency of racing high-speed rotation , as well as long-term reliable service life.

At the same time , car unit of the car rear axle designed for reliable quality shaft mounting and rotating concentric with the real and the low friction ball locking device , thereby slewing bearing‍ providing the best speed, rigidity and response . In addition, a high-performance engine bearings are also racing to give a more ample power , rigidity and reliability. Also located in this race means outer surface and patented groove profile Group is designed to avoid this during the game supporting devices due to the risk of dislocation caused .

The concept of mechanical spindle

It refers to a mechanical spindle rotation axis of the workpiece or tool drive on the machine. Usually consists of a spindle, bearings and transmission parts (gears or pulleys) etc. spindle components. The machine is mainly used to support transmission parts such as gears, pulleys, transmit motion and torque, such as machine tool spindle; some for clamping workpieces, such as a mandrel. In addition planer, broaching machine and other main motion to linear motion outside, most machines have a spindle assembly. Motion accuracy and structural rigidity spindle unit is an important factor in determining the processing quality and cutting efficiency. Performance indicators to measure the spindle assembly is mainly rotational accuracy, rigidity and speed of adaptation. ① rotation accuracy: radial and axial grinding spindle is rotated in the direction of impact precision beating occur (see geometric tolerance), mainly on the manufacturing and assembly quality spindle and bearings. ② dynamic and static rigidity: The main decision of the bending stiffness of the spindle, the bearing stiffness and damping. ③ speed adaptation: the maximum permissible speed and speed range, primarily determine the structure and lubrication in bearings, and cooling conditions.
