Cylindrical roller producer in China: There are numerous types available, and many have no inner rings. The drawn-cup type has a pressed steel outer ring and the precision (solid) type has a machined outer ring. There are also cage-and-roller assemblies without rings. Most bearings have pressed steel cages, but some are without cages. Except the following types are available, the HF and CF series are also obtainable in JnSn (Just ask!). SCE and SCE-PP Series – Drawn cup needle roller bearing, Open ends for through shafts, cage guided, with/without seals, Inch dimensional. NJ Series – Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and a fixed rib on the inner ring which can guide the shaft in a single direction (axially). NUP Series – Are single row bearing roller cylindrical and have two fixed ribs on the outer ring and, on the inner ring, a fixed rib and a support washer. This way they can be used as locating bearings, guiding the shaft axially in both directions. RNU Series – Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and has no inner ring. Instead, it uses the shaft as the opposing raceway.

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.
The wheel hub bearing has a high speed and a large force, which requires the use of suitable grease, and the internal design of the clearance is relatively large, which puts forward higher requirements on the production of raw materials. The force and working conditions of automobile bearings are more complicated than those of motorcycles. For example, the bearing of the automobile condensing fan motor should take into account the continuous working condition of the motor under high temperature conditions and so on. In garden tools represented by lawn mowers, gearboxes have extremely high requirements for the sealing of the bearings, neither allowing the grease in the box to penetrate into the bearings nor leak the grease. Due to the higher pressure in the gearbox, the bearing is also required to have a special pressure relief function. Discover more details on https://www.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.
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.
