Structural Features Of Tapered Roller Bearings

The type code of tapered roller bearings is 30000

and the tapered roller bearings is a separate bearing. In general, especially in GB / T307 The outer ring and inner assembly of tapered roller bearing within the size range involved in 1-94 tolerances for radial bearings of rolling bearings can be used interchangeably. The angle of the outer ring and the diameter of the outer raceway are the same as the overall dimensions, which are standardized and are not allowed to be changed during design and manufacturing.

So that the outer ring and inner components of tapered roller bearing

can be interchanged all over the world. Tapered roller bearings is mainly used to bear the combined radial and axial load dominated by radial load. Compared with angular contact ball bearing, tapered roller bearing has large bearing capacity and low limit speed. Tapered roller bearing can bear axial load in one direction and limit axial displacement of shaft or shell in one direction.

Tapered Roller Bearings

Introduction to linear bearing series

Linear bearing is a low-cost linear motion system

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. 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, Tapered Roller Bearings 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. Tapered Roller Bearings If 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 Oil lubrication Tapered Roller Bearings  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 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: Tapered Roller Bearings 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, 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 and its support rigidity is stronger, Tapered Roller Bearings 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. Tapered Roller Bearings 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. Tapered Roller Bearings 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. 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,

Generally, two sets of bearings are installed in pairs,

with their outer ring wide end face opposite (back-to-back) or Tapered Roller Bearings 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, 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 Tapered Roller Bearings 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, the locking port is on the inner ring, which can be adapted to higher speed.
