NSK cylindrical roller bearing
Cylindrical roller bearing rolling elements are radial rolling bearings of cylindrical rollers. Cylindrical rollers and raceways are line contact bearings. Load capacity, mainly bear radial load. The rolling element has little friction with the ferrule rib and is suitable for high speed rotation.
Introduction of NSK cylindrical roller bearing
According to the ferrule with or without ribs, NSK cylindrical roller bearings are divided into single row bearings such as NU, NJ, NUP, N, NF, and double row bearings of NNU and NN. The bearing is a structure in which the inner ring and the outer ring are separable. Cylindrical roller bearings with no ribs on the inner or outer ring, the inner and outer rings can move relative to the axial direction, so they can be used as free end bearings. A cylindrical roller bearing with a single rib on one side of the inner and outer rings and a single rib on the other side can withstand a certain degree of axial load in one direction. Steel stamping cages or copper alloy cages are generally used. However, some use polyamide shaped cages.
1.NSK cylindrical roller bearing Roller and raceway are in line contact or repair line contact, and have large radial load capacity, suitable for heavy load and impact load.
2.NSK cylindrical roller bearing has small friction coefficient and is suitable for high speed. The limit speed is close to deep groove ball bearing.
3.NSK Cylindrical Roller Bearings Types N and NU can be moved axially to accommodate changes in the relative position of the shaft and housing due to thermal expansion or mounting errors. They can be used for free end support.
4.NSK cylindrical roller bearing The machining requirements of the shaft or the seat hole are relatively high. After the bearing is installed, the relative deflection of the outer ring axis should be strictly controlled to avoid contact stress concentration.
5.NSK cylindrical roller bearing The inner or outer ring can be separated for easy installation and disassembly.
NSK cylindrical roller bearing main use
Large and medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and lifting and transporting machinery.
