which is very convenient for installation and disassembly. Cylindrical roller bearings are divided into single row, double row and multi row cylindrical roller bearings.
Single row cylindrical roller bearings are divided into n-type with no retaining edge on the outer ring and double retaining edge on the inner ring, nu type with no retaining edge on the inner ring and double retaining edge on the outer ring, NJ type with double retaining edge on the outer ring and single retaining edge on the inner ring,
NF type with double retaining edge on the inner ring and single retaining edge on the outer ring, Cylindrical Roller Bearing NUP type with double retaining edge on the outer ring and single retaining edge on the inner ring and flat retaining {todayhot} ring, etc.
Double row cylindrical roller bearing is divided into cylindrical inner hole and conical inner hole. It has the advantages of compact structure, strong rigidity,Cylindrical Roller Bearing large bearing capacity and small deformation after load. It is suitable for machine tool spindle support.
do not limit the relative axial displacement between the shaft and the housing, and are used for non positioning bearings. FCD shaped four row cylindrical roller bearing, ring and rolling element components can be easily separated, and the cleaning, inspection and disassembly of the bearing are very convenient. It is mostly used in heavy machinery such as cold rolling mill and hot rolling mill.
which is used for infinite stroke and cylindrical shaft. Because the bearing ball is in point contact with the shaft, the service load is small. Cylindrical Roller Bearing The steel ball rotates with minimal friction resistance, so as to obtain high-precision and stable motion.
Linear bearings are widely used in precision equipment such as electronic equipment, tensile testing machines and digital three-dimensional coordinate measuring equipment, as well as sliding parts of industrial machinery Cylindrical Roller Bearing such as multi axis machine tools, punches, tool grinders, automatic gas cutting machines, printers, card sorting machines, food packaging machines and so on.
grease Inject anti-corrosion oil into the linear bearing. If grease is used for lubrication, Cylindrical Roller Bearing remove the anti-corrosion oil with kerosene or organic solvent, and add grease after air drying.
It is recommended to use adhesive mark N0 2 lithium soap grease Oil lubrication if the anti-corrosion oil does not need to be removed when lubricating with oil, the lubricating oil with ISO viscosity grade vg15-100 can be selected according to the Cylindrical Roller Bearing temperature change
can be supplied from the oil supply pipe or from the oil hole on the outer bearing seat. Cylindrical Roller Bearing Since the sealing ring will scrape off the lubricating oil, oil lubrication is not suitable for bearings with sealing rings without holes. Linear guide bearing:
A groove or ridge made of metal or other material. A device that can bear, fix, move a device or equipment and reduce its friction. A longitudinal groove or ridge on the surface of a guide rail for guiding and fixing machine parts, special equipment, Cylindrical Roller Bearing instruments, etc.
Guide rail is also widely used in our daily life, such as the sliding slot of sliding door, train track and so on.
namely radial thrust ball bearing, can be loaded with more steel balls, its radial bearing capacity is greater than that of ordinary ball bearing, and can also bear large axial load or pure axial load at the same time. Its allowable working speed is similar to that of deep groove ball bearing and its support rigidity is stronger, but it requires accurate installation and is very sensitive to axis misalignment error,
Generally, it does not need to bear the radial load alone, but it must bring additional axial load while bearing the radial load. This kind of bearing has many variants and is widely used. It is often made into three series with 15 °, 25 ° and 40 ° contact angles. The larger the contact angle is, the higher its axial load capacity is. However, it is appropriate to use a small contact angle at high speed.
Most of these bearings are used in pairs for small-span rigid double support shafts or precision spindles. When in use, the clearance should be carefully adjusted. By changing the axial distance between the inner and outer rings of the bearing, the internal clearance of the bearing can be adjusted.
At the same time, several sets of bearings can be installed in parallel and given a certain pre interference, which can improve the rigidity of the bearing system.
