Cylindrical Roller Bearing High Speed Rotation
Inner or outer ring without ribs cylindrical roller bearings, Cylindrical Roller Bearing the inner ring and outer ring can be relative to the axial movement, it can be used as a free end bearing. In the inner and outer ring on one side of a double ribs, the other side of the ring with a single ribbed cylindrical roller bearings, can withstand a certain degree of axial load in one direction. General use of steel stamping cage, Cylindrical Roller Bearing or copper alloy car system solid cage. But also part of the use of polyamide forming cage.
Cylindrical roller bearings roller and raceway line contact, radial load capacity. Both for heavy load and impact load, but also for high-speed rotation, while improving the roller end face and the contact area of the lubrication conditions, improve the performance of the bearing. Bearing the WeChat is very worthy of attention! Generally applicable to large and medium-sized motors, locomotives and rolling stock, machine tool spindle, Cylindrical Roller Bearing internal combustion engine, generator, gas turbine, gear box, rolling mill, vibrating screen and lifting transport machinery.
1. Roller and raceway for line contact or repair off-line contact, radial load capacity, suitable for heavy load and impact load.
2. Friction coefficient is small, suitable for high speed, Cylindrical Roller Bearing limit speed close to deep groove ball bearings.
3. N-type and NU-type axial movement, can be adapted to thermal expansion or installation error caused by the relative position of the shaft and the shell changes can be used for free end support.
4. The shaft or seat hole processing requirements are higher, the bearing after the installation of the outer axis of the relative deflection to be strictly controlled, Cylindrical Roller Bearing so as to avoid contact stress concentration.
5. The inner or outer ring can be separated, easy to install and disassemble
Cylindrical roller and raceway line contact, radial load capacity. Both for heavy load and impact load, but also for high-speed rotation.
Cylindrical roller bearing raceway and rolling body was geometric shape. Cylindrical Roller Bearing After improved design, the new structure design with high load carrying capacity, rib and roller end face not only improves the axial bearing capacity of the bearing, but also improves the lubrication condition of the contact surface of the roller end face and the rib Bearing the use of performance.
The material used to manufacture the bearing parts has a significant effect on the performance and reliability of the rolling bearing. General considerations for bearing rings and rolling elements include: hardness associated with load carrying capacity, fatigue resistance under lubrication conditions and different cleanliness conditions, and dimensional stability. For the cage,Cylindrical Roller Bearing consider the friction, strain and inertial forces, Cylindrical Roller Bearing and in some cases also consider the chemical effects of certain lubricants, solvents, coolants and refrigerants. The relative importance of these considerations is also affected by other operating parameters such as corrosion, high temperature, shock load, or the combined effects of these factors.
