NF Series
Single-row cylindrical roller bearings are usually only subjected to radial force. Compared with ball bearings of the same size, the radial bearing capacity is increased by 1.5-3 times, with good rigidity and impact resistance. It is especially suitable for rigid supports and short shafts. Axial displacement of shafts caused by thermal elongation and installation and disassembly require machine accessories of separable bearings.
NF type has ribs on one side of the outer ring and ribs on both sides of the inner ring. It can also bear a certain amount of unidirectional axial load. Therefore, this type of structure is suitable for use as a unidirectional axial locating bearing.
Features:
Low friction coefficient, suitable for high speed.
The inner or outer ring can be separated for easy installation and removal.
It can move axially and can adapt to changes in the relative position of the shaft and the casing caused by thermal expansion or installation errors, and can be used as a free end support.
The processing requirements for the shaft or seat hole are high, and the relative deflection of the outer ring axis after the bearing is installed should be strictly controlled to avoid contact stress concentration.
