2212 ETN9 - Double Row Self-aligning ball bearings 60*110*28mm-manufacture,factory,supplier from China

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.

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

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.

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.

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

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.

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.

Double row angular contact ball bearings can bear large radial loads, mainly radial and axial combined loads and torque loads, limiting the axial displacement of both sides of the shaft.

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.

Product Description:Q195 carbon steel coil due to its good plasticity, can be used to manufacture light steel keel, can be easily processed into various shapes of keel, and can withstand a certain building load.

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.

Categories:Rolling bearings: commonly found in truck transmission systems, such as tapered roller bearings, spherical roller bearings, etc.Plain bearings: common in the steering system of trucks, such as linear bearings, hydraulic bearings, etc.Three.Rolling bearings: By rolling the roller (ball or roller) between the inner ring and the outer ring, to achieve load transfer and reduce friction.Plain bearings: Through the oil film sliding between bearings, to achieve load support and reduce friction.Bearing NumberDimensions(mm)dDB566425.H195 80079293.8148135566426.H195 58107968125115566427.H195

The unidirectional thrust ball bearing comprises a shaft ring, a seat ring and a ball-cage assembly. It can be separated and the shaft ring, seat ring, ball-cage assembly can be installed separately. Unidirectional thrust ball bearings can withstand the axial load in a single direction and can be positioned in a single direction, but must not bear any radial load.The 51130 belongs to the single direction thrust ball bearings, also called ball thrust bearings or axial deep groove ball bearings. These bearings consist of a shaft ring, a housing ring and a ball and cage assembly.

1. good assembly performance, and clearance adjustment can be omitted.2. light weight, compact structure and large load capacity.3. in order to seal the bearing, the lubricating grease can be installed in advance, the external hub seal can be omitted and the maintenance can be avoided.4.The main role of wheel bearings is to bear the weight and provide precise guidance for the rotation of the wheel, which is subject to both axial and radial loads.

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.

One of the largest aspects of the needle curler bearing is the sketch of the needle roller. The needle roller has a smaller diameter than different sorts of rolling elements, so it can obtain a greater load carrying capability in a constrained space.

Railway Bearings play an important role in both passenger and goods transport.  They have to withstand heavy loads: they work at high speeds, under a great weight, are  Rolling bearings in railway gearboxes must withstand a wide variety of operating conditions and complex environmental influences. Not only are high static and, in particular, dynamic loads present in the form of vibrations and shocks, but the rolling bearings are also operated intermittently below the permissible minimum load.

The single-row four-point contact ball slewing bearing has the characteristics of compact structure and light weight, which makes it widely used in construction machinery. Because the steel ball and the circular raceway contact at four points, this support can bear axial force, radial force and heeling moment at the same time, with high bearing capacity and stability.
