The Structure and Characteristics of Cylindrical Roller Bearings
Cylindrical roller and the raceway was in line contact, radial load capacity, both suitable for FB090 bronze bushing WB802 Harden Bronze Bushes
for heavy and shock load, but also for high-speed rotation.
N-type and NU-type axial movement, can be applied to agricultural machinery bearings should be due to thermal expansion or installation error caused by the relative position of the shaft and shell changes, the most suitable for free-end bearings.
NJ type and NF type can withstand a certain degree of axial load, NH type and NUP type variable speed cylinder copper sleeve to withstand a certain degree of two-way axial load. Inner or outer ring can be separated for easy assembly and disassembly.
NNU type and NN type of anti-radial load rigidity, mostly for machine tool spindle.
FC.FCD.FCDP type can withstand a larger radial load, mainly used for rolling mill roll.
Such TGLWN T shaped slide bearing, bronze slide oilless plate
are mainly used for medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, slowdown devices, handling handling machinery, various types of industrial machinery.
Single row cylindrical roller bearings
The NU and N types allow the shaft to move axially with respect to the housing over a range of dimensions, making it suitable for free-end bearings.
NJ-type and NF-type can withstand a certain degree of one-way axial load.
NUP type and NFP type can withstand a certain degree of axial movement in both directions, it is suitable for free-end bearings.
Double row cylindrical roller bearings
Double row cylindrical roller bearings sub-cylindrical hole and tapered hole two.
There are also bearings with oil hole and oil groove in the outer ring.
Most of these bearings for machine tool spindle, but can also be used for other occasions.
Four row cylindrical roller bearings
Four-row cylindrical roller bearings,sliding contact bearing
can withstand a large radial load and impact load, high precision, suitable for high-speed. Most of the rolling mill used in the roll, but can also be used for other occasions.
