NACHl's self-aligning roller bearings are a common and important industrial part, widely used in a variety of mechanical equipment and construction machinery. It is mainly composed of an outer ring, an inner ring, a roller, a cage and other components, and supports the rotating and swinging shaft through rolling friction. Aligning roller bearing has large radial load capacity and high axial load capacity, as well as excellent self-aligning performance, and can adapt to the relative tilt and axial change between shaft and seat when working.

According to the different requirements of bearings and bearing seats, the classification of bearing seats is not exactly the same, and it is necessary to carefully check the selection according to the design when using.1 Classification according to the shape of the bearing seat:1.1 Outer spherical bearing with seat, also known as bearing unit (SKF). When there is no bearing, it is called the outer spherical bearing seat. 1.1.1.1 The outer spherical bearing seat is divided into 200 series according to the bearing series. The 500 series. The 300 Series. The 600 Series.

Bearing unit includes1. Double row angular contact ball bearings, from automotive hub bearings series a high load capacity, high roll stiffness, double sealCorrosion protection machined bearing housing2. Threaded pin with positioning surface3. Lock washer4. There are high-performance three-lip box seals on both sides of the bearing to prevent pollution.

Some typical insulating bearing materials include ceramic, graphite and the famous polytetrafluoroethylene (PTFE). Ceramics are widely used in the bearing industry because of their hard diamond, wear-resistant gold and outstanding insulation properties. Graphite is widely used in bearings because of its extremely low friction and high lubrication. PTFE is widely used because of its excellent corrosion resistance and strong insulation. According to actual needs, designers and engineers can also choose other special materials to build insulated bearings.

The separation bearing is composed of a racetrack ring, a needle roller and a cage assembly, and can be used in any combination to thin or thick racetrack rings. The non-separable bearing is an integral bearing composed of precision stamped raceway ring, needle roller and cage assembly that can withstand unidirectional axial loads. This bearing occupies a small space, which is conducive to the compact design of the machine.

Angular contact ball bearing 70000 type, composed of outer ring, inner ring, steel ball, cage.

Sliding bearings are sliding friction, with large contact surface, simple structure, small volume, strong bearing capacity, good vibration resistance, but large friction coefficient, easy to generate heat, need sufficient lubrication, suitable for low speed and heavy loadRolling bearings are rolling friction, compared with sliding bearings, their contact surface is small (point contact for ball bearings, line contact for roller bearings), small friction coefficient, less heat generation; less wear and tear, good accuracy retention; suitable for higher speeds run down.

The sliding bearing seat is composed of an upper cover, a base, a split bearing bushing (aluminum bronze) and mounting bolts, which mainly bear radial load. Easy to use, no need to install bearings. The load-free part of the inner surface of the bearing bush is provided with an oil groove, and the lubricating oil flows into the gap through the oil inlet hole and the post groove.

The outer ring of the needle roller bearing is precisely stamped with thin steel plate, which has small structural space and large load capacity. It is suitable for occasions where installation space is limited and housing holes are not suitable for raceway.

Thrust roller bearing is an important mechanical part, which is used to support the axial load acting on the rotating parts. Its use is directly related to the stable operation and life of mechanical equipment, so it should be paid attention to. Advantages of thrust roller bearings The processing technology of thrust roller bearings is very precise, and the production accuracy of its inner ring, outer ring and raceway can reach sub-micron level.

RU cross roller bearings are also known as bearings. The main body of a rolling body usually uses cylindrical or tapered rollers to intersect a single flow path, separated by retainers or spacers, and arranged in a cross pattern. Therefore, the cross roller ring group can withstand loads in all directions, with a stiffness of 3-4 times higher than traditional models. RU cross roller bearing is lubricated by spray. Drilled shrinkage air mixes spray and lubricating oil to produce oil mist.

Sliding bearings are sliding friction, with large contact surface, simple structure, small volume, strong bearing capacity, good vibration resistance, but large friction coefficient, easy to generate heat, need sufficient lubrication, suitable for low speed and heavy loadRolling bearings are rolling friction, compared with sliding bearings, their contact surface is small (point contact for ball bearings, line contact for roller bearings), small friction coefficient, less heat generation; less wear and tear, good accuracy retention; suitable for higher speeds run down.

Thrust roller bearings are used to bear axial and radial combined loads based on axial loads, but the radial load shall not exceed 55% of the axial load.

Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types  1 Type: Single row deep groove ball bearings,Stainless steel deep groove ball bearings,Single row deep groove ball bearings with filling slots,Double row deep groove ball bearings 2.

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 insulated bearing adopts a special spraying process to spray high-quality coating on the outer surface of the bearing. The coating has strong adhesion to the substrate and good insulation performance, which can avoid the electric corrosion of the bearing by the induced current, prevent the damage of the current to the grease, the rolling element and the raceway, and improve the service life of the bearing. The process is constantly improving. In insulated bearings, the outer ring or inner ring surface has a layer of 100μm thick coating, which can withstand voltages up to 1000V DC.
