Stamped Outer Ring Needle Roller Bearings-manufacture,factory,supplier from China

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.

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.

Needle roller bearing is a common mechanical part, which is mainly used to support the movement of the rotating shaft. The working principle of the needle roller bearing is to use the rolling body (needle roller) to roll between the inside and outside, thereby reducing friction and resistance, so that the bearing can withstand larger loads and rotational speeds.The structure of the needle roller bearing is relatively simple, consisting of an inner ring, an outer ring, a needle roller and a cage.

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.

The outer ring double guard (or double lock ring) with cage needle roller bearing NA, NKI type, can be installed respectively inner ring and outer ring (with lock ring, a full set of needle roller and cage), high speed, divided into single and double row two. Such needle roller bearings with inner rings may be used if the shaft cannot be used as a raceway, i.e.

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.

Needle roller bearing is a common rolling bearing, using needle roller as the rolling body, can withstand the radial and axial load.Structure: Needle roller bearings are mainly composed of outer ring, inner ring, needle roller, cage and seal. The shape size of the needle roller bearing is small, saving space, suitable for limited space design.

Structural features: The roller inside the cross roller bearing is combined in a cross arrangement, which makes the bearing able to withstand both radial and axial loads. There is a certain gap between the inner and outer rings, which can make the bearing maintain high rigidity when it is subjected to high torque load, and also has good rotation accuracy and stability. The design of the seal ring and cage of the cross roller bearing is also very important, which can effectively prevent dust and foreign matter from entering the bearing interior and extend its service life.

Combined needle roller bearings, a special type of bearing, can be added between the inner and outer rings of the needle roller components to achieve balance accuracy, reduce vibration and noise effects.

1.Needle roller bearings for stamping outer rings. There are two kinds of bearings: perforated type and sealed type. The needle roller bearing has no inner ring, and the needle roller directly contacts the surface of the shaft, so the processing accuracy and heat treatment hardness of the shaft should be the same as that of the bearing inner ring.2. Solid ring needle roller bearings solid ring needle roller bearings, commonly used solid ring needle roller bearings are NA type and RNA type.3. Roller needle bearing4. Needle roller and cage assembly.

Rotary bearing is an important mechanical component, which is widely used in various industrial equipment and mechanical devices. It bears the radial load, axial load and moment load under the rotating motion, and plays the role of support and rotation. The following will introduce the structure, working principle, application field and maintenance of the rotary support bearing in detail.Rotary support bearings are usually composed of an inner ring, an outer ring, a rolling element (ball, roller, etc.) and a cage.

The working principle of needle roller bearings is to use rolling friction to reduce friction and resistance. When the bearing is subjected to axial or radial load, the needle roller rolls between the inner and outer rings, thereby reducing friction and resistance.

The different types of cylindrical roller bearings are designated based on their structural features and intended applications: N..EM: Cylindrical roller bearing with a standard inner ring without any ribs, suitable for radial loads. NU..EM: Bearing with aremovable inner ring and two integral flanges on the outer ring, designed for high radial loads and accommodates axialdisplacement. NJ..EM: Features a removable inner ring and one integral flange on the outer ring, primarily used for applicationswhere axial displacement is required.

 Thrust needle and retainer assembly are comosed of a set of tray ring gaskets combined with retainer with roller bearings.The stand leads and holds many rolling elements.The thrust needle bearings or thrust-cylindrical roller bearings can support the bearings with the axial directional load and so the can be used as the bearings with good rigidity and minium axial occupied spaces.If the surface of the adjacent parts can be used as a tray for the rolling needles and the holding stand assembly should be recommended when the support space is big enough so that a small axial cross secti

IKO is a well-known manufacturer specializing in the production of various types of needle roller bearings, and its needle roller bearing products enjoy a high reputation around the world. IKO's needle roller bearings have a variety of excellent characteristics, and the following will describe the characteristics and applications of its needle roller bearings in detail.First of all, IKO's needle roller bearings are made of high-quality materials, have extremely high wear resistance and corrosion resistance, and can operate stably in a variety of harsh environments.

These bearings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc., which requirecompactness, high rigidity and high rotational accuracy. In addition, bearings made of stainless steel and those with inner and outer rings provided with mounting holes are also available on request. Please contact us.Crossed Roller Bearings are compact bearings with their rollers alternately crossed at right angles to each other between inner and outer rings.

Axial (Thrust) needle roller bearings are units comprising axial needle rollers and cage assemblies and axial bearing washers with a centring spigot. Axial (Thrust) needle roller bearings are able to accommodate heavy axial loads. They are insensitive to shock loads and provide a high degree of bearing units stiffness within a minimum axial space. They represent unidirectional bearings and can accommodate axial loads acting in one direction only.Using axial (thrust) needle roller bearings, it is possible to make compact bearing units.

Product Description:The thickness specifications of CSB galvanized steel coil are diverse, and the thinner thickness is suitable for some products that are more sensitive to weight and cost and do not need to bear too much pressure, such as internal shielding covers of electronic equipment, small packaging boxes, etc.

The deep groove ball bearing with dust cover and sealing ring has been filled with appropriate grease during assembly, and should not be heated or cleaned before installation. No further lubrication is required during use, and the operating temperature is between -30 ° C and +120 ° C.NSK deep groove ball bearings generally consist of two bearing rings with complete raceways. The rolling element is mounted between the rings and rolled on the raceway. The rolling parts can be balls, cylindrical rollers, needle rollers, tapered rollers, or barrel rollers.
