Introduction To Linear Bearing Series

Linear bearing series is a low-cost linear motion system

which is used for infinite stroke and cylindrical shaft. Linear Bearing Series Because the bearing ball is in point contact with the shaft, the service load is small. 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, Linear Bearing Series tensile testing machines and digital three-dimensional coordinate measuring equipment, as well as sliding parts of industrial machinery such as multi axis machine tools, punches, tool grinders, automatic gas cutting machines, printers, card sorting machines, food packaging machines and so on.

Lubrication and friction

grease Inject anti-corrosion oil into the linear bearing. Linear Bearing SeriesIf grease is used for lubrication, 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

Introduction To Linear Bearing Series

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 temperature change Linear Bearing Series Shaft lubrication can be supplied from the oil supply pipe or from the oil hole on the outer bearing seat. 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. Linear Bearing Series A longitudinal groove or ridge on the surface of a guide rail for guiding and fixing machine parts, special equipment, 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.

Characteristics of angular contact ball bearings

Characteristics Of Angular Contact Ball Bearings

Angular contact ball bearing,

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 Linear Bearing Series 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. Linear Bearing Series 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. Linear Bearing Series 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.

A single bearing of this type can only bear the axial load in one direction. Linear Bearing Series At the same time, other bearings need to be configured to offset their additional axial forces. When installed in pairs, their additional axial forces offset each other, and they can bear the axial load of two forces upward, and have strong axial limit capacity in two directions,


Linear Bearing Series two sets of bearings are installed in pairs, with their outer ring wide end face opposite (back-to-back) or narrow end face opposite (face-to-face), in which the rigidity of the back-to-back installation bearing system. In order to facilitate installation in pairs or groups, some bearing factories supply bearings in pairs, three sets in groups and four sets in groups.

In this way, Linear Bearing Series the processing consistency of the supplied bearings in the same batch is good, the load is borne more evenly during use, and the additional axial forces offset each other more thoroughly.

This type of bearing can be divided into two types: separated type and non separable type. The separated type bearing is used when the installation conditions are limited and the outer ring or inner ring is required to be removed from the whole set of bearings for separate installation.

Because the separated type angular contact ball bearing is widely used in magneto, it is also called magneto bearing. In this type of bearing, Linear Bearing Series the locking port is on the inner ring, which can be adapted to higher speed.
