TYPES OF BEARINGS

There are many types of bearings,  and the bearings that need to be used for different equipment, speed and accuracy are also different. The types of bearings are classified according to the size of rolling bearings: miniature bearings, small bearings, medium and small bearings, medium and large bearings Bearings, large bearings, extra large bearings. Bearings are divided into ball bearings and roller bearings according to the types of rolling elements.
Among them, roller bearings are divided into: cylindrical roller bearings, needle roller bearings, tapered roller bearings, and spherical roller bearings according to the type of rollers. Bearings can be divided into self-aligning bearings and non-aligning bearings according to whether they are self-aligning during operation.
Bearings are classified according to the type of rolling bearing structure: radial bearings, thrust bearings, axial contact bearings, and thrust angular contact bearings.
So what are the detailed types of bearings? Now let’s learn together
1. How much do you know about crossed roller bearings?
The rollers of cylindrical roller bearings are usually guided by the two ribs of one bearing ring. The cage rollers and the guide ring form a combination, which can be separated from the other bearing ring, which is a separable bearing.
This type of bearing is easy to install and disassemble, especially when the inner and outer rings are required to have an interference fit with the shaft and housing. This type of bearing is usually only used to bear radial load, only the single-row bearing with ribs on the inner and outer rings can bear a small steady axial load or a large intermittent axial load.
Application areas: large motors, machine tool spindles, axle boxes, diesel engine crankshafts, automobiles, gearboxes that keep in mind, etc.
2. Tapered roller bearings
This type of bearing is equipped with truncated truncated rollers, which are guided by the large rib of the inner ring. The design makes the vertices of the conical surfaces of the inner ring raceway surface, the outer ring raceway surface and the roller rolling surface cross the centerline of the bearing. point above. Single-row bearings can carry radial loads and one-way axial loads, while double-row bearings can carry radial loads and two-way axial loads, and are mainly used to carry heavy loads and impact loads.
Applications: Automotive: Front wheels, rear wheels, transmissions, differential pinion shafts. Machine tool spindles, construction machinery, large agricultural machinery, gear reduction devices for railway vehicles, rolling mill roll necks and reduction devices.
Fourth, the joint bearing
The spherical plain bearing is a kind of curved rolling bearing. Its rolling contact surface is an inner curved surface and an outer curved surface. It can also rotate and shake in any direction during fitness exercise. Made of various unique processing techniques. The bone joint bearing has the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, and good lubrication.
Five, four-point contact ball bearings
It can carry radial load and bidirectional axial load. A single bearing can replace the angular contact ball bearing with front combination or back combination, and it is more suitable for carrying pure axial load or composite load with relatively large axial load components. This type of bearing can carry any One of the contact angles can be generated when the axial load is in any direction, so the ferrule and the ball are always in point contact with two sides and three knives on any contact line.
Application areas: aircraft jet engines, gas turbines.
6. Thrust cylindrical roller bearings
It consists of washer-shaped raceway rings (shaft washers, seat washers), cylindrical rollers and cage assemblies. Cylindrical rollers are produced and processed with convex surfaces, so the pressure distribution between the rollers and the raceway surfaces is uniform, and it can bear one-way axial load, with large axial load capacity and strong axial rigidity.
Application areas: oil drilling rigs, iron and steel machinery.
7. Thrust needle roller bearings
Separable bearings are composed of raceway rings, needle rollers and cage assemblies, and can be combined arbitrarily with stamped thin raceway rings or cut and machined thick raceway rings. Non-separable bearings are integral bearings composed of precision stamped raceway rings, needle rollers and cage assemblies, which can carry unidirectional axial loads. Such bearings occupy a small space and are beneficial to the compact design of machinery. Most of them only use needle roller and cage assemblies, and use the assembly surface of the shaft and the housing as the raceway surface.
Application areas: speed change devices for automobiles, cultivators, machine tools, etc.
Eight, thrust tapered roller bearings
This type of bearing is equipped with a truncated truncated roller (the big end is a spherical surface), and the roller is accurately guided by the rib of the raceway ring (shaft washer, seat washer), and is designed so that the raceway surface of the shaft washer and the seat ring and the rollers roll The apex of each conical surface of the surface intersects at a point on the center line of the bearing, the one-way bearing can carry one-way axial load, and the two-way bearing can carry two-way axial load.
Application field One-way: crane hook, oil rig swivel. Bidirectional: rolling mill roll neck.
Nine, high-precision, high-rigidity, high-load, high-speed turntable bearings
Rotary table bearings have high axial and radial load carrying capacity, high tilt stiffness and extreme precision, and are suitable for bearing arrangements in rotary tables as well as in measurement and experimentation. When installing this type of bearing, it is necessary to control the tightening torque of the mounting screws.
10. Slewing bearing and non-standard customization
Slewing bearing can bear large radial load, axial load and overturning moment and other comprehensive loads at the same time. It integrates various functions such as support, rotation, transmission, and fixing. Heavy-duty low-speed occasions, such as lifting machinery, excavators, rotary tables, wind turbines, astronomical telescopes and tank turrets, are widely used.
A complete range of bearings and customization of non-standard bearings are available to assist customers in testing and mass production.
