1. Centripetal needle roller and cage assembly (Type K)2, needle roller bearings with double locking rings (NA, NKI, RNA, NK)3. Single row needle roller bearing with double rib on outer ring (NA, NKI, RNA, NK)4, double row needle roller bearings with double guard (NA type, RNA type)5, stamped needle roller bearings (HK type, BK type)Note: This bearing has low cost, large bearing capacity, and is suitable for supporting structures with limited installation size. The journal surface is hardened as a rolling surface, and the bearing is pressed into the seat hole without axial positioning.

High temperature resistant bearing: The material itself has resistance to high temperature 1200 ℃, and good self-lubrication, tem- perature between 100℃ to 800℃ should not produce temperature difference caused by the expansion.

The structural design of the stud CAM follower needle bearing consists of an end plate integrated into the inner ring (stud) and another inner shoulder ring pressed against the stud. In this design, both ends of the stud have lubrication holes to ensure that the bearing can be fully lubricated during operation. The inner ring is hardened by induction, which can improve the hardness and wear resistance of the inner ring, thus extending the service life of the bearing.

When the rotary support bearing is working, the inner and outer rings realize relative rotation through the combination of rolling elements. When the external force acts on the bearing, the load is transmitted to the inner and outer rings, and is transmitted to each other through the rolling element, achieving the carrying capacity. At the same time, the rolling motion of the rolling element reduces the friction force and improves the rotation efficiency of the bearing.

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.

Koyo tapered roller bearing is a common rolling bearing, usually used in automobiles, mechanical equipment, wind turbines and other fields.

Railway bearing is an important component used to support and guide the rotation of railway vehicle axle, which bears the weight of the train and the force generated during operation, and can ensure the smooth operation of the train. Railway bearings play a vital role in railway transportation, and their quality and performance directly affect the safety and efficiency of trains. Railway bearing is an indispensable component in railway transportation, its structure is firm, reliable quality, wear-resistant and durable, to ensure the safety, stability and efficient operation of the train.

Linear motion bearing is 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 very little friction resistance, thus achieving smooth motion with high precision. Linear motion bearing metric and Imperial series: Standard type (LM/LME/LMB... UU), adjustable (LM/LME... UUAJ), Open (LM/LME... UUOP); Extended (LM/LME... LUU); Flange type (LMF/LMK/LMH... UU, LMEF/LMEK... UU), flange extension (LMF/LMK/LMH... LUU, LMEF/LMEK...

Miniature Flanged Ball Bearing are simple structure and easy to use, are the most widely application bearing, mainly used to support radial load.  This kind of bearings with small friction coefficient, low noise, high speed limit, but is not able to bear impact strike, not suitable for a heavy load.  According to the user's requirements, we can provide high precision (P6 ,P5), all kinds of clearance and vibration noise level (Z1 and Z2 or V1, V2) bearing.The flanged bearing enables the bearings to be axially located in the housing, such an arrangement is very simple in design and

First of all, one of the characteristics of FAG deep groove ball bearings is a simple structure, consisting of an outer ring, an inner ring, a steel ball and a cage. This simple structure makes the installation and maintenance of deep groove ball bearings more convenient and fast.Secondly, the bearing capacity of FAG deep groove ball bearings is large and can withstand both radial and axial loads.

Product Description:Q215 carbon steel coil is one of the commonly used materials for manufacturing welded steel pipes. Through crimping, welding and other processes, carbon steel coils can be made into steel pipes of different diameters and wall thicknesses, which are widely used in water supply and drainage, gas transmission, heating pipes and other fields. It can also be used to manufacture various accessories in the pipeline system, such as elbows, tees, quads, etc.

Product Description:In interior decoration, it can be used to make decorative strips, partitions, screens and so on. Its diverse cross-section shapes and processing methods can create a rich decorative effect.

The working principle of thrust roller bearing is to transmit and bear axial load through the linear movement of thrust roller. When the axial load acts on the bearing, the thrust roller will roll along the slide of the inner and outer rings to realize the load transfer.

The DAC type auto front wheel bearing is a double row angular contact ball bearing incorporating an integral outer ring and two separable inner rings; which is available either with seals or without seals. Wheel bearings (hub bearing) main role is to load and for the rotation of the hub to provide accurate guidance, both axial load radial load again, is a very important component. Traditional automotive wheel bearing is composed of two tapered roller bearings or ball bearings combination, bearing installation, oiled, and adjust the clearance seals are conducted in automotive production line.

Hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings, it will be two sets of bearings as one, with good assembly performance, can be omitted clearance adjustment, light weight, compact structure, large load capacity, for sealing bearings can be loaded in advance grease, omit the external hub seal and free from maintenance and other advantages, has been widely used in cars, There is also a trend of gradual expansion of applications in heavy-duty vehicles.1.

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.

Thrust tapered roller bearings can form a very compact bearing configuration, which can withstand very heavy axial loads, is not sensitive to impact loads, and has good rigidity. LYTBZ produces unidirectional tapered roller bearings and bidirectional tapered roller thrust bearings. The screw fixed bearing constitutes a specially designed unidirectional tapered roller thrust bearing and is filled with rollers.Thrust tapered roller bearing features:This bearing is used for rolling mill screw fixed bearing configuration.

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.
