Engineering Machinery Bearing have a large carrying capacity and are suitable for supporting structures with limited installation dimensions.The surface of the journal is hardened as the rolling surface, and the bearing is fitted into the seat hole with a press fit, and there is no need for it to be axially positioned.The bearing should be injected with an appropriate amount of grease before installation.Usually, no relubrication is required after assembly (BK type bearings are used in the support of the journal without the protruding end, the end face is closed for sealing, and can withstand

This type of bearing is widely used in industrial automatic robots, working machinery and medical facilities, where high rigidity, tightness and high speed are required to ensure accuracy.

Trucks are very common tools in the transportation industry, carrying important goods and supplies. Truck bearing is one of its key components, it plays an important role in the vehicle transmission system support and operation. Its quality and running state directly affect the safety and stability of the vehicle.

Secondly, the rolling body is an important part of the flange bearing, the main role is to carry the load between the inner ring and the outer ring and reduce friction. Common rolling elements are steel balls, rollers, rollers, etc., and their number and size are determined according to the design and working requirements of the bearing, which can achieve efficient rotating motion.The cage is an assembly that connects the rolling elements and maintains the spacing between the rolling elements to ensure that they remain in relative position while in operation.

Bearing seat is a mechanical part for mounting bearings, which usually has two parts: a seat body fixed on the machine tool and a bearing seat sleeve fixed with the seat body. The role of the bearing seat is to support the bearing and ensure that the bearing can be correctly installed on the shaft of the machine equipment to withstand the load brought by the bearing in the rotating motion.The bearing seat is usually made of a high-strength metal or steel material to ensure that it has sufficient strength and stiffness to support the bearing.

There are two main types of bearings widely used in industrial robots: constant cross-section thin-walled bearings and RU cross roller bearings. The bearing of an industrial robot is one of the key components suitable for the joints of industrial robots or the turntables of machining centers, robots, medical devices, measuring instruments, IC manufacturing equipment, etc., and has a wide range of uses.

(1)Linear motion bearing is a kind of low-cost metal for producing linear motion system, which is used for infinite stroke cylindrical shaft.. Because point contact ball bearing with shaft, so using the load is small.  (2) the flange linear bearing can be divided into: round flange type, method type, elliptical flange type, guided round flange, guiding method, guide the elliptical flange type, extended round flange type.(3)According to the specification is divided into two series of LM and LME series.

The sealing and protection of truck bearings are also very important. Trucks often drive in a variety of harsh road conditions, bearing in dust, water vapor and chemicals and other corrosive environment. In order to extend the life of the bearing, it is necessary to take into account the sealing property in the design, and select the appropriate sealing material and structure.Truck bearings also have certain requirements on installation and maintenance. Proper installation and proper lubrication are the keys to ensure the normal operation of truck bearings.

Thrust ball bearings are produced as single direction or double direction thrust ball bearings. They are designed to accommodate axial loads only and must not be subjected to any radial load.Thrust ball bearings are separable, the shaft washer, housing washer(s), ball and cage assembly(s) can be mounted separately. Shaft washers have a ground bore to enable an interference fit.

These bearings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc., which requirecompactness, high rigidity and high rotational accuracy. In addition, bearings made of stainless steel and those with inner and outer rings provided with mounting holes are also available on request. Please contact us.Crossed Roller Bearings are compact bearings with their rollers alternately crossed at right angles to each other between inner and outer rings.

Railway bearings play a key role in the railway transportation system, mainly in the following aspects:1. Bear and transfer loadsRailway bearings can withstand the axle load of the train, and ensure the stability of the track during the operation of the train by distributing the load pressure. They are able to accept loads of hundreds of tons on EMUs or locomotives and transfer them to the tracks, reducing wear on the tracks and other vehicles.2.

The working principle of Koyo tapered roller bearings is to use the rolling body to roll between the inner and outer rings, thereby reducing the contact area and reducing friction resistance. When the external radial or axial load is applied, the roller will bear the load between the inner and outer rings to achieve the function of supporting and transferring the load of the bearing. Rollers are designed so that they can equally share load when rotating, reduce local stress and extend service life.

1.Needle roller bearings for stamping outer rings. There are two kinds of bearings: perforated type and sealed type. The needle roller bearing has no inner ring, and the needle roller directly contacts the surface of the shaft, so the processing accuracy and heat treatment hardness of the shaft should be the same as that of the bearing inner ring.2. Solid ring needle roller bearings solid ring needle roller bearings, commonly used solid ring needle roller bearings are NA type and RNA type.3. Roller needle bearing4. Needle roller and cage assembly.

The range of four-row tapered roller bearings is wide, including not only the traditional design with an intermediate ring between the outer ring and/or the inner ring, but also the modification of the four-row tapered roller bearings with an integrated middle ring and the bearing ring.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)Grease lubrication speed (r/min)Oil lubrication speed (r/min)Weight (kg)302027202E15351114.913.412000160000.053302037203E17401220.821.89000120000.079302047204E20471428.230.58000100000.126302057205E25521532.2377000900

NTN tapered roller bearings are mainly used to bear radial and axial combined loads mainly based on radial loads, with high stiffness and rotation accuracy, and have large bearing capacity and low limit speed compared with angular contact ball bearings. Its carrying capacity depends on the Angle of the raceway of the outer ring, and the greater the Angle, the greater the carrying capacity.

The series of products with flanges on the outer wheel make the axial positioning easy; The bearing seat is no longer needed and becomes more economical. In order to obtain low friction torque, high rigidity and good rotation accuracy of bearings, steel balls with small outer diameter are used. The use of hollow shafts ensures lightweight and wiring spaceThe biggest feature is that the flange and the bearing are integrated.

The insulated bearing is a specially designed bearing whose internal structure can effectively isolate the external environment and prevent conductive and conductive heat. Insulated bearings are usually used in special industrial environments or in equipment requiring special protection.Structure composition: The insulated bearing is composed of an inner ring, an outer ring, a rolling body, a cage and a seal.
