Cylindrical roller bearing structure and characteristics
Cylindrical roller line contact with the raceway, large radial load capacity, suitable for both FB090 bronze bushing to withstand heavy load and impact load, but also for high-speed rotation.
N type and NU type can move axially, can be adapted agricultural machinery bearings should change due to thermal expansion or installation of shaft and housing relative position error caused most suitable for sealed roller bearings.
NJ-type and NF type can withstand a certain degree of axial load, NH type and NUP type can luffing cylinder sets of copper to withstand a certain degree of axial load. Inner or outer ring detachable, easy assembly and disassembly.
Rigidity NNU and NN-type anti-radial load, mostly for machine tool spindle.
FC.FCD.FCDP type can withstand higher radial loads, mainly used for PTFE graphite bronze bushings.
Such bearings are mainly used for medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, handling machinery, industrial machinery.
Single row cylindrical roller bearings
NU type and N-type shaft relative to the housing to allow within a certain range for axial movement, therefore suitable for free end bearing.
NJ-type and NF type can withstand a certain degree of axial load.
NUP type and NFP type can withstand a certain degree of both directions of axial movement, therefore suitable for free end bearing.
Double row cylindrical roller bearings
Double row cylindrical roller bearings Cylindrical and tapered bore two kinds.
Another hole and the outer ring of the bearing oil sump.
Most of these bearings for machine tool spindle, but can also be used for other occasions.
Four row cylindrical roller bearings
Four row Conveyor Bearing with Ball Bearing can withstand the big radial load and impact load, high precision, suitable for high speed. Mostly applied to the rolling mill rolls, but can also be used for other occasions.
