Best needle roller bearing supplier factory: NNU Series – Are double row cylindrical roller bearing manufacturers and have three 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 NNU Series bearings have no virtually thrust capacity. RNA 48 Series – Needle roller bearings that have metric dimensions, without Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 48 Dimensional Series. RNA 49 Series – Needle roller bearings that have metric dimensions, without Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 49 Dimensional Series. RNA 69 Series – Needle roller bearings that have metric dimensions, without Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 69 Dimensional Series.

HK Style Standard Needle Roller Bearings are commonly referred to as drawn cup needle bearings due to the shape of the bearing housing. Drawn cup needle roller bearings with open ends are needle roller bearings with a very small radial section height. They comprise thrust needle roller bearing, thin-walled, drawn cup outer rings and needle roller and cage assemblies which together form a complete unit. This needle roller bearing types use small, cylindrical rollers which are long and narrow. These bearings allow for a large surface area to be in contact with the outer race, and are much more compact than cylindrical rollers.
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. Read more details at jnsnbearing.com.
Single row deep groove ball bearings 6200 series with a ring groove can simplify the installation technically, as the bearings can be inserted with a locking ring into the housing in the axial direction. The nap rings are used on the outside edge. This saves time and space. The appropriate locking rings can be supplied separately (supplement N) or pre-assembled on the bearing (supplement NR). Both open (unsealed) and steel shields or rubber seals versions of the single-row deep groove ball bearings are available, and they are all pre-lubricated with grease. While many different retainers are available, ball bearings use standard cages of pressed steel, as well as machined, brass cages for high-speed applications. Deep groove radial ball bearings are used to transmit loads from rotating parts to housings with minimum friction loss. This will be obtained by a high hardness, minimizing the deformation of the bearing elements. Additional design measures ensure an undisturbed free rolling action, the measures includes the radial clearance, materials and precision.
The company adheres to the concept of “customer-oriented, standard-oriented, and profit-assisted”, and has established a good reputation in the bearing industry. Its products are sold to more than ten countries such as the United States, the United Kingdom, Sweden, and Germany. With excellent and stable quality instead of imports, it has won unanimous praise from customers at home and abroad. Company profile – HangZhou Jnsn Bearing Imp& Exp Co., Ltd is a company specializing in designing, manufacturing, trading of a wide range of bearings. Core technical members is active in developing popular bearing product and try fast development of new products, we always aim at quality first. OEM service is also available, we accept to customize based on the drawing or original sample.
Easy Interchange – Designed as metric bearings, our deep groove ball bearings follow ISO standards and are dimensionally interchangeable with competitor metric products. Premium Lubricants – For reduced torque and a quieter operation, premium lubricant comes standard on all sealed and shielded deep groove ball bearings. This grease has a temperature range from -29℃ to 177℃. Brass Cage Availability – Deep groove ball bearings with brass cages (available in select sizes) can deliver extra strength and durability in the most unrelenting conditions: extreme shock loads, high vibrations and high forces due to acceleration. Quiet Running for Electric Motor Quality – Deep groove ball bearings are frequently used in electric motor applications to minimize vibration and noise.
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.
