Top needle roller bearing manufacturer
Cylindrical roller bearing manufacturer supplier in China: 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. 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.

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.
NU Series cylindrical roller bearings are single row bearings and have two fixed ribs on the outer ring and one smooth inner ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. Therefore, NU Series rolling bearings are used in non-locating bearing units. Also, the NU Series bearings have no virtually thrust capacity. NJ cylindrical roller bearing tends to posses a collar on its inner race at one end. This collar is normally positioned in such a way that it transfers the axial load in the shaft to the rolling elements. This is the type of cylindrical roller bearing which is capable of carrying axial load to a certain extent. The extent of the axial load that can be carried by the bearing is dependent only on the specific bearing.
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. See even more info on https://www.jnsnbearing.com/.
Deep groove ball bearings can be used in generators, small motors, electric fans, power tools, vacuum cleaners, conveyor, packaging machine, drilling machine, conveyor, variable, washing machine, optical instruments and so on. Single row radial ball bearing 6200 series are available in Metric and Inches, and there are three seal types reachable– rubber seals, metal shields, or just open. Also we have several material options for the bearing, plastic, chrome steel, stainless steel, ceramic, carbon steel and etc. This series features deep-honed raceways resulting in a perfectly balanced bearing. For 6200 series of deep groove ball bearing, its structure is simple and easy to use, it consists of four elements that including inner ring, outer ring, cage that holds balls and ball bearing. It is mainly used to bear radial load, but when it increases the radial clearance of the bearing, it has certain angular contact ball bearing performance and can withstand combined radial and axial loads. It can also be used to withstand pure axial loads when the rotational speed is high and thrust ball bearings are not suitable. Compared with other types of bearings of the same size as deep groove ball bearings, these bearings have a small coefficient of friction and a high limit speed.
The company has rich experience in the industry of bearing production and export. We focus on not only the domestic market, but also the international market. Moreover we integrate R&D, production and export of bearings. We constantly strive for research and innovation development, adhere to the concept of “survival of high quality”, and provide excellent service for customers. Our employees receive professional training. Our competence to work out a proposal that springs a “before vs after” clear your worries. Our concept of “ survival of high quality” urges us to attach great importance to our products quality and price, thus we have absolute strengths on them.
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 deep groove ball bearings are widely used in household appliances, toys, bicycles, pumps, skateboard, electric power tools, gearbox, car motors and other fields. Thin-walled deep groove ball bearing is with thin width or thin height size of deep groove ball bearing. And the thin wall ball bearings are different from conventional deep groove ball bearings in that cross-section of each series are designed to be a fixed size, which do not increase as an inner diameter increased. The 6700 series bearings are a thin section bearing and are single row deep groove ball bearing, and the use of small outer diameter steel balls can reduce friction significantly. Thin section ball bearings have a bearing inner diameter to outer diameter ratio that is less than a specified value. The thin wall metric dimensional series deep groove ball bearing has the characteristics of small size, light weight and low friction. It is in a small size and light weight, has space saving, weight reduced and external dimensions reduced, low friction and having good rotation accuracy.
