Retentors, usually made of steel or synthetic materials, are used to hold rolling elements in position, ensuring that they maintain the correct clearance and position relationship with each other during use.Single-row angular contact bearings are suitable for all kinds of rotating machinery, such as automobile wheels, motors, fans, etc., which can withstand high-speed operation and large loads.When installing, it is necessary to pay attention to the cleaning and lubrication of the bearing to ensure its performance and life.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter

Needle roller bearings are equipped with thin and long rollers (roller length is 3 to 10 times the diameter, the diameter is generally not greater than 5mm), so the radial structure is compact, its inner diameter size and load capacity are the same as other types of bearings, and the outer diameter is the smallest, especially suitable for radial installation size limited support results.

Single row angular contact ball bearings mainly used forundertaking combined load both from radius and axle andalso for pure axle load,rotator speed is high.Material of bearings is choosed on refining bearing steelGCr15 (100Cr6，SUJ2,S2100) and other type of bearingsteel,balls are adopting GCr15 (100Cr6，SUJ2,S2100) orceramic.

The outer diameter (OD) of the cam follower (stud or yoke) can be the standard cylindrical shape or be crowned. Crowned cam followers are used to keep the load evenly distributed if it deflects or if there is any misalignment between the follower and the followed surface. They are also used in turntable type applications to reduce skidding. Crowned followers can compensate for up to 0.5° of misalignment, while a cylindrical OD can only tolerate 0.06°. The only disadvantage is that they cannot bear as much load because of higher stresses.

Agricultural bearings are used in conveyors, lawn mowers, combines, hay balers, planters/grain drills, augers, cotton strippers, and more.  They are designed to stand up to extreme conditions and loads.  There are many different designs available.  Their basic components are inner and outer rings, balls, and retainers.  The inner race can be round, square, or hex, and the outer race can be either cylindrical or spherical.  Most agricultural bearings are sealed on both sides with single, double, or triple lip.New domestic modelsOld domestic modelInner diameter (mm)Outer

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

One of the biggest features of the needle roller bearing is the design of the needle roller. The needle roller has a smaller diameter than other types of rolling elements, so it can achieve a higher load carrying capacity in a limited space.

1: High load capacity and accuracyThe internal structure of the bearing is the same as that of the single row deep groove ball. While bearing a large radial load, it can bear axial loads in both directions.The accuracy of the bearing is the same as that of the general accuracy, and it has high rotation accuracy and good high-speed performance2: reasonable aligning structure and the most suitable cooperationThe bearing assembly has the aligning property through the spherical outer diameter bearing and the bearing seat with the spherical inner hole.

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.

Ball bearing with eccentric locking collar is  outer diameter in spherical surface,internal construction is the same as deep groove ball bearings of 6200 6300 series.they both can sustain radial and axial loads.We can supply full series of UC200,UC300,SA200,SB200,UEL200,UK200,SER200,CS200,UC300 series bearings.Such bearings are often used in severe operating conditions where they are exposed to dirts,moisture and high temperature.thus,insert ball bearing are usually with grease groove and oil hole on outer ring,at suitable time,we need to replace fresh grease to secure full performance an

High load carrying capacity    The cage bars are displaced relative to the roller pitch diameter to enable the rollers to be placed closer to each other, creating room for additional rollers  High stiffness    The increased number of rollers increases radial stiffness.    High speed capabilityThe cage designs are suitable for high speeds, rapid accelerations and peak loads.  Long service life  The black oxide coating of rings and rollers (designation suffix L4B) contributes to extended service life by improving:     

Because the rolling body in the thrust tapered roller bearing is a tapered roller, the rolling surface can form a pure rolling and the limit speed is higher than that of the thrust cylindrical roller bearing because the rolling bus and the raceway bus of the washer converge at a certain point on the axis line of the bearing.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)294169039416801705446813802000–5.9129412903941260130422938542700—2.61294139039413651404534410002500—3.342

Advantage of UC215-48 BearingThe service life of the bearing is prolonged.Its code is uk200 series and uk300 series. This kind of outer spherical ball bearing has a tapered inner hole with an inner diameter of 1:12, which should be used in conjunction with the tightening sleeve.

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.

Thrust roller bearings are used to bear axial and radial combined loads dominated by axial loads, but the radial load shall not exceed the axial load55%. Compared with other thrust roller bearings, this kind of bearing has lower friction factor, higher speed and aligning performance.29000, type bearing rod for the asymmetric spherical roller can reduce the relative sliding of the roller and raceway in the roller, and the roller is long, large diameter, the number of rollers, high load capacity, usually using oil lubrication, individual low speed can be grease lubrication.

NSK automotive hub bearing is a key component used to support the rotation of automotive wheels. It uses high-quality bearing steel materials and advanced manufacturing processes to ensure the durability and performance stability of the bearing. NSK automotive hub bearings are usually composed of inner and outer rings, bearing balls (rollers), cages, sealing rings, etc. They can withstand the weight of the vehicle, reduce friction, improve rotation efficiency, and resist vibration and impact forces to ensure safety and stability when the vehicle is running.

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.

The popular riding machine for a stud kind cam follower is a slot, for use with a flat head screwdriver. However, hex sockets are accessible for greater torquing ability, which is specifically beneficial for eccentric cam followers and these used in blind holes.

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. Traditionally, bearings for automotive wheels are made of two sets of tapered roller bearings or ball bearings combined, and the mounting, oiling, sealing and clearance adjustment of the bearings are carried out on the automotive production line.
