NSKNJ2315EC Cylindrical roller bearings:
NSKCylindrical roller bearing isusually by a wall bearing rings of the two lead, Cage, and guide roller rings composed of a combination of things, the general type of bearing is detachable.NSKCylindrical roller Bearing this installation, the demolition of more convenient, especially when requested, and the outer shell and shaft are fit more shows its advantages.NSK Cylindrical rollerBearing this kind generally used for radial load to bear, only, the outer wall with all the separate bearings can withstand axial loading smaller or larger batch of axial load. The same size and shape of the deep groove ball bearings, bearing with such a large radial load capacity of the structure from the point of view, also applies to high-speed rotation.
NSK Cylindrical roller bearingand the raceway crown used it to design modification to eliminate the edge of the stress and improve bearing life.
DF wall design of a certain angle, so the bearer of the axial load greater than the more conventional design.
No inner or outer wall with wall cylindrical roller bearings
NU-cylindrical roller bearings, its outer wall with two on, and no inner wall.
N-type cylindrical roller bearings, at two of its inner wall, and no outer wall.
NU and the N-type cylindrical roller bearings, in a certain range relative to the bearing axis to allow me to make axial displacement of two-way, that could take the shaft caused by thermal expansion changes in the length, as it applies to non-bearing position. To be capable of sustaining their large radial load, but can not afford to axial loading.
NSKCylindrical rollerbearings produces cylindrical roller bearings in many designs, dimension series and sizes. The majority are single row bearings with a cage. Single and double row full complement bearings (without cage) complete theNSK standard assortment for general engineering. Bearings with a cage can accommodate heavy radial loads and operate at high speeds. Full complement bearings are suitable for very heavy radial loads at moderate speeds.
The rollers ofNSK cylindrical roller bearings are a key component. Their geometry, the so-called logarithmic profile, provides an optimum stress distribution in the contact zones in the bearing. Their surface finish maximizes lubricant film formation and optimizes rolling motion of the rollers. The benefits derived from this compared with traditional designs include enhanced operational reliability and a greater insensitivity to misalignment.
