Cylindrical Roller Bearing Position Change
Cylindrical roller with raceway for wire contact bearing. Load capacity, Cylindrical Roller Bearing mainly bear radial load. Roller and ferrule friction small, Cylindrical Roller Bearing suitable for high-speed rotation. NING, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings. Cylindrical Roller Bearing The bearing is the inner ring, the outer ring can be separated from the structure.
Inner or outer ring without cylindrical roller bearings, Cylindrical Roller Bearing the inner and outer ring can be relative to the axial movement, Cylindrical Roller Bearing it can be used as a free end bearing. In the inner and outer rings on one side of the 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.
1. Roller and raceway for line contact or repair line contact, radial bearing capacity, suitable for heavy load and impact load.
2. Friction coefficient is small, suitable for high speed. Cylindrical Roller Bearing Extreme 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 bearings are separate bearings, Cylindrical Roller Bearing installation and removal is very convenient. Cylindrical roller bearings can withstand large radial loads and are suitable for use in high-speed applications.
This type of bearing allows the inner ring axis and the outer ring axis angle error (inclination) is very small, only 2 '~ 4'. As a result, the machining accuracy of the shaft and the bearing housing is relatively high, otherwise uneven load or stress concentration tends to occur at the raceway contact site. Cylindrical Roller Bearing But the roller or raceway contact bus can be amended to reduce the occurrence of stress concentration.
Cylindrical roller bearings according to the number of rolling elements installed with different, can be divided into single row,Cylindrical Roller Bearing double row and multi column cylindrical roller bearings and other different structures. Different structural bearings are also shown in the position design of the ribs. One of the commonly used cylindrical roller bearings in the following forms:
Single row cylindrical roller bearings: single row cylindrical roller bearings are separable bearings, easy to install and disassemble, two rings can be used with a tight fit, Cylindrical Roller Bearing modified roller and raceway between the contact line can reduce the stress concentration.
Double row cylindrical roller bearings: double row cylindrical roller bearings are swimming bearings, the separability of the installation and removal is very convenient. Both rings can be tightly fitted. Double row cylindrical roller bearings are barely inclined.
N-type bearing outer ring without ribs, Cylindrical Roller Bearing both sides of the inner ring with ribs. It is possible to allow the shaft to move axially upwardly relative to the bearing housing. NU type bearing outer ring on both sides of the ribs, inner ring without ribs. Cylindrical Roller Bearing It is also possible to allow the shaft to displace in both axial directions between the bearing housings. Therefore, this type of structure is suitable for use as a swivel bearing.
