2. Cylindrical Roller Bearing :
Cylindrical roller bearings, with the least friction quotiety, are
suitable for high-speed rotation. The rollers have linear contact
with the raceway, and the bearings can carry heavier radial load.
NJ and NF type of bearings have some loading capacity in one-way
axial direction, and NH and NUP types can accept certain axial load
in two directions. With the linear contact between cylindrical
rollers and raceways, provides a high load capacity, which make the
cylindrical roller bearings can carry big radial load and impact
load.
3 . Cylindrical Roller Bearing Features :
N: The inner ring has two integral flanges and the outer ring is
without flanges. Axial displacement of the shaft with respect to
the housing can be accommodated in both directions within the
bearing itself. Pressed steel and machined brass cages and allowed.
NU: The outer ring has two integral flanges and the inner ring is
without flanges. Axial displacement of the shaft with respect to
the housing can be accommodated in both directions within the
bearing itself. Pressed steel and the machined brass cages are
allowed.
NJ: The outer ring has two integral flanges and the inner ring has
only one integral flange. The bearings are therefore suitable for
the axial location of a shaft in one direction. Pressed steel and
machined brass cages are allowed.
NF: The inner ring has two integral flanges and the outer ring has
only one integral flange. The bearings can locate a shaft axially
in one direction. Pressed steel and machined brass cages are
allowed.
NUP: The outer ring has two integral flanges and the inner ring has
one integral flange with one separating as flange ring. The
bearings can be used as locating bearings, i.e. They can provide
axial location for a shaft in both directions.
4 . Competitive Advantage:
a. Compare with the trading company, as we have our own factory
b. Compare with the factory we are easy communicated.
c. Our products were produced under strict quality test system.
