Needle bearing supplier factory in China
Cylindrical roller manufacturing factory today: BK, and BK-RS Series – Drawn cup needle roller bearing, One end closed for shaft ends, cage guided, with/without seals, Metric dimensional. NCS Series – Needle roller bearings that have inch dimensions precision ground raceways with ribs, without Inner Rings, cage guided rollers, with/without Seals. NK Series – Needle roller bearings that have metric dimensions, precision ground raceways with ribs, without Inner Rings, cage guided rollers, with/without Seals. NF Series – Also able to carry incidental thrust loads, this cylindrical bearing types features two integral ribs on the inner ring and a single rib on the outer ring. NN Series – Bearings of NN design are double row cylindrical roller bearing and have three fixed ribs on the inner ring that retain the rollers and cage and one smooth outer ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. Therefore, N Series rolling bearings are used in non-locating bearing units. Also, the NN Series bearings have no virtually thrust capacity. Read additional information on https://www.jnsnbearing.com/cylindrical-roller-bearings.html.
Its main features are low cross-section height and high load carrying capacity. Mainly used for bearing arrangements that are compact, inexpensive, and the bore of the bearing housing cannot be used as the raceway for the needle roller cage assembly. The bearing and bearing housing must be installed in an interference fit. If the axial positioning function such as the box shoulder and the stop ring can be omitted, the inner hole of the bearing housing can be made extremely simple and economical. The drawn cup needle roller bearings mounted on the shaft end are open on both sides and closed on one side. The base end face of the closed stamped outer ring can withstand small axial guiding forces.
NJ type cylindrical roller bearings have ribs on both sides of the outer ring, and the inner ring has ribs on one side. Can withstand a certain amount of one-way axial load. The outer ring of the cylindrical roller bearing NJ type has a rib on one side and a rib on both sides of the inner ring. It can also withstand a certain amount of one-way axial load. Therefore, this type of structure is suitable for use as a unidirectional axially oriented bearing. The cylindrical roller bearings are widely used in large and medium motor, locomotive vehicle, machine tool spindle, internal combustion engine, generator, gas turbine, gearbox, rolling mill, vibrating screen and so on.
In addition to the above-mentioned industries, in industrial motors, the bearings used are usually required to withstand heavy loads, and the bearing environment is relatively harsh. Bearings in motors such as household appliances such as air conditioners and washing machines have very strict requirements for low noise and high rotation accuracy. Jnsn bearing company is a professional best bearing manufacturer integrating bearing design, research and development, manufacturing, and trade. It can also provide ceramic, high-temperature, low-temperature, low-friction and other special-purpose types of bearings. The main products include best ball bearing, linear bearings, needle roller bearings, angular contact bearings, thin-walled bearings, tapered roller bearings, joint bearings, etc. Find more information at https://www.jnsnbearing.com/.
F6000 series bearings are very similar to normal grooved ball bearings, and the only difference is that this type ball bearings have a flange on the outer ring, which can be very useful for mounting the bearings in through holes or axial location. Flanged deep groove ball bearings F6000 series are available in open, shielded and sealed options. The shields and sealed options provide protection to prevent debris and dust getting into the bearing, while at the same time retaining the grease to ensure good lubrication and a long service life. Metric sized deep groove radial flanged ball bearings can bear heavy radial loads and moderate thrust loads in both directions. These bearings are made to the same sizes as standard bearings 6000 series. They also have a flange, which allows flush fitting into housings up to the flange shoulder. This type of bearing is often used on steel tracks to act as both a guide and a support. Deep groove ball bearings are widely used bearings. They use uninterrupted raceways, making them an excellent choice for radial loads. This design achieves precise tolerances even at high speeds.
Our own manufacturing factory is specialized in producing deep groove ball bearings, self-aligning ball bearings, spherical roller bearings, single row tapered roller bearings, inch tapered bearings, automotive bearings, bearing joints, etc. The annual production capability is more than 960 million units.

Our market positioning matches yours and our commitment resonates with you.
Premium grease for high performance, low torque and less noise – Extra light bearings are normally used in applications where space limitations are a primary consideration and shaft sizes are relatively large. 6000 series deep groove ball bearing can support radial loads despite their low weight. Compared to deep groove ball bearings of the 6300 medium series they require a smaller installation space at the same inside diameter, only weigh half of them and allow higher speeds. Within their basic load ratings, these bearings are capable of radial, thrust or combined loads. These bearings are available in open, sealed or shielded configurations. This series is also available in stainless steel.
The diversity of thin wall ball bearings makes them suitable for a wide range of applications, such as aerospace, semiconductor processing equipment, robotics, medical equipment and other fields. F6700 series is a deep groove ball bearing with a flange on one side of the outer ring. When using this bearing, it is not necessary to provide a step on the inner bore of the housing, so it is possible to process the through hole with high accuracy. Since this bearing is attached to the end face of the housing as a standard, it is necessary to machine the right angle of the housing end face with high accuracy. Single-row flanged deep groove ball bearings F6700 series are available in open and sealed designs. They are designed for high to very high speeds and can accommodate radial as well as axial forces. Flanged bearings are recommended when housing designs cannot accommodate full bearing width, or where the quality of the housing bore is a concern. Moreover, because of their simple design, low operating temperature, and low friction, flanged deep groove ball bearings have a longer expected shelf life than other bearings. They do not require additional lubrication after installation, which also means less maintenance downtime.
