Auto parts NSK NTN KOYO taper roller bearing/Cylindrical roller bearing/Spherical roller bearing
Product Description
Tapered roller bearings mainly bear the combined radial and axial loads mainly in the radial direction. The bearing capacity depends on the raceway angle of the outer ring, and the larger the angle, the greater the bearing capacity.
This type of bearing is a separable bearing, and tapered roller bearings are usually separable, that is, the tapered inner ring assembly composed of the inner ring with the roller and cage assembly can be installed separately from the tapered outer ring (outer ring). According to the number of rows of rolling elements in the bearing, it is divided into single row, double row and four row tapered roller bearings.
Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries
Cylindrical roller bearing Cylindrical rollers and raceways are linear contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the rib of the ring is small, which is suitable for high-speed rotation. According to whether the ring has ribs or not, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller bearings such as NNU and NN. The bearing is a structure in which the inner ring and the outer ring can be separated
Cylindrical roller bearings are used in large and medium-sized motors, locomotives, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and hoisting and transportation machinery, etc.
Spherical roller bearings have two rows of rollers, which mainly bear radial loads, as well as axial loads in either direction. It has high radial load capacity, especially suitable for working under heavy load or vibration load, but cannot bear pure axial load. The outer ring raceway of this type of bearing is spherical, so its self-aligning performance is good, and it can compensate for the coaxiality error.
Mainly applicable cages: stamped steel cage (suffix E), glass fiber reinforced polyamide 66 cage (suffix TVPB), machined brass solid cage (suffix M), stamped steel cage for vibration occasions (suffix JPA) )
Main uses: papermaking machinery, reduction gear, railway vehicle axles, rolling mill gearbox bearing housings, rolling mill rolls, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers, vertical self-aligning bearings with seats .
