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.

1.Cylindrical hole· With two rows of steel balls and a curved raceway in the outer ring, self-aligning ball bearings can be actively aligning· and can accept the point of view error between the shaft and the bearing seat. It is suitable for the working condition that simply shows the shaft deflection and the shaft error caused by different centers· Friction is the lowest of all rolling bearings· has only a small temperature rise even at high rotational speeds.2.

Railway shaft double row tapered roller bearings have the following characteristics:High load bearing capacity: Double row tapered roller bearings are designed with two rows of rollers, so they can withstand large radial and axial loads.High temperature resistance: suitable for high-speed operation and high temperature environment, with good heat resistance.Strong aligning ability: can maintain good working performance when bearing installation is not accurate or axial displacement.Easy assembly and disassembly: double row tapered roller bearing structure is relatively simple, easy disassembly

Aligning roller bearings have two rows of rollers, mainly bearing radial loads, but also can withstand axial loads in either direction. It has high radial load capacity, especially suitable for heavy loads or dynamic loads, but cannot withstand pure axial loads. This kind of bearing outer ring raceway is spherical shape, so its aligning performance is good, can compensate for the coaxial error.Self-aligning roller bearings are divided into two different structures according to the roller cross section shape: symmetrical spherical roller bearings and asymmetric spherical roller bearings.

Angular contact ball bearing has high limit rotational speed, they can carry radial load and axial load simultaneously, they can also withstand purely radial load. The axial load carrying capacity depends on the magnitude of contact angle and increases with increasing contact angle. Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools, for which high running accuracy is required.Single row angular contact ball bearings can carry axial load acting in one direction only.

Double row deep groove ball bearing:Design: With two balls, these bearings can handle a higher load capacity than a single row of bearings.Application: They are suitable for bearing arrangements where the bearing capacity of a single row of bearings is insufficient, for example in heavy industry applications.Features: Double-row bearings are slightly wider than single-row bearings, but offer better load distribution and improved reliability for demanding applications.Both single-row and double-row boring deep groove ball bearings are designed with high-quality materials to ensure durability an

Single row tapered roller bearing is a common rolling bearing, which is composed of an inner ring, an outer ring, a roller and a cage. Its structure is similar to a conical shape, which is why it gets its name.The contact points on the inner and outer rings are conical and suitable for bearing large loads in both radial and axial directions.

Double row angular contact ball bearings correspond, in their design and operation, to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space.

Product Description:The DX53D substrate has a lower carbon content than the DC01 substrate used in the DX51D+Z galvanized steel sheet.

Hub bearings can fix the tire and support the gravity of the whole body, provides precise guidance for the rotation of the hub. wheel hub bearing enables the wheels and attached components to rotate smoothly and keeps the wheel attached to the car. High quality wheel hub assembly make you enjoy your vehicle in a safe and smoothWheel bearing assemblies manufactured by high-quality materials for ensuring precisely matches, durability, reliability and premium performance.

INA needle roller bearings have excellent quality and performance and are widely used in various industrial fields. It uses needle roller as the rolling body, compared to ball bearings, needle roller bearings have higher load capacity and smaller dimensions, suitable for limited installation space.

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.

Truck bearings are an important automobile component, mainly used to support the weight of the vehicle and keep the tire connected to the chassis of the vehicle. The following are the main components of truck bearings:Outer ring: The outer ring is the outer metal ring of the bearing, usually made of steel or other metal. The outer ring is responsible for bearing the external weight and force, and supports and stabilizes the vehicle by connecting to the vehicle chassis.Inner ring: The inner ring is the inner metal ring of the bearing, usually also made of steel or other metal.

Bearing capacity: NTN angular contact bearings have high bearing capacity and can withstand large radial and axial loads. In the process of use, the axial load of the bearing will cause the contact pressure between the inner and outer rings to increase, so it is necessary to choose the appropriate contact Angle to improve the bearing capacity.Rotation accuracy: NTN angular contact bearings have high rotation accuracy, which can ensure that the mechanical equipment has stable rotation performance during operation.

Hub bearing (HUB) is the main role of load-bearing and provide accurate guidance for the rotation of the hub, it bears both axial load and radial load, is a very important component. The traditional automobile wheel bearing is composed of two sets of tapered roller bearing or ball bearing. The installation, oiling, sealing and clearance adjustment of the bearing are all carried out on the automobile production line.

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.

Stamped outer ring needle roller clutch, commonly known as one-way bearing or one-way needle roller bearing,  is a single directional bearing composed of a thin-walled outer ring, cage, spring plate,  and needle roller that is stretched from an alloy sheet. It can be used as a converter, check device,  and overrunning clutch, and is widely used in fitness equipment, cash counting machines, washing machines,  fishing gear, toy cars, and other transmission parts that need to have a reverse stop function.

Linear bearings with flanges Performance: Linear bearings are a linear motion system produced at a low cost for use with unlimited travel and cylindrical shafts. Because the bearing ball is in point contact with the shaft, the load is small. The steel ball rotates with minimal friction resistance, thus achieving smooth motion with high precision.

Thrust cylindrical roller bearings are often combined into high-stiffness bearing configurations that can withstand heavy loads and vibration loads without difficulty. Such bearings can withstand large axial loads in a single direction, but they cannot withstand radial loads, and they have no automatic aligning capability.
