Machined Type With Inner Ring Needle Roller Bearing Clutch NA4907 -manufacture,factory,supplier from China

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.

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.

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.

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.

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.

High Rigidity Type Crossed Roller Bearing V has a solid one-piece construction for both inner and outer rings. Therefore, high accuracy and high rigidity are achieved, and mounting errors can be minimized. As separators are incorporated between the cylindrical rollers for smooth rotation, these bearings are suitable for applications where rotation speed is comparatively high.

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.

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.

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.

Rolling bearing with seat is a common and widely used in various mechanical equipment bearings, which support and transmit rotating motion through rolling elements, with high load capacity and stability. Below I will describe in detail the structure, working principle and application areas of rolling bearings with seats, hoping to help you better understand this knowledge.A rolling bearing with seat is usually composed of several basic parts, such as an inner ring, an outer ring, a rolling element (such as a steel 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.

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.

 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

A double-row tapered roller bearing is a common bearing type that consists of two tapered rollers mounted on an inner ring and an outer ring. It can withstand large radial and axial loads and is able to maintain high accuracy and stiffness while rotating at high speeds.Double row tapered roller bearings are designed so that the inner and outer rings can be adjusted separately to achieve axial and radial preloading.

Since a bearing can choose different bearing seats, and a bearing seat can choose different types of bearings at the same time, there are many varieties of bearing seats. Bearing seat is included, many large foreign bearing companies also have their own bearing seat type record. However, the same bearing housing model is not marked exactly the same in different company samples.

This type of bearing is widely used in industrial automatic robots, working machinery and medical facilities, where high rigidity, tightness and high speed are required to ensure accuracy.
