Cylindrical roller bearing manufacturer from HangZhou Jnsn Bearing
5 min readTop rated needle bearing producer: 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. 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. Discover even more details on cylindrical roller bearing supplier.
The drawn cup roller clutches bearings HF style comprise thin-walled, drawn outer cups with a series of ramps on the inside diameter, steel cages and needle rollers, which serve as clamping elements. Steel or plastic springs hold the needle rollers in their clamped position. Drawn cup roller clutches can transmit high torques in one direction and are particularly compact in a radial direction. The roller clutches are available with and without support bearing arrangements.
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. See extra information at 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.

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.
