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. Cylindrical Roller Bearings are bearing in which cylinders are used as the rolling elements as opposed to balls in ball bearings. As such, the rollers have a greater (linear) contact area with the outer ring and are distribute loads across a broader surface. Subsequently, they have a relatively high radial load capacity and are suitable for high speeds. As one of the best cylindrical roller bearing suppliers in China, Jnsn Bearing has been specialized in cylindrical bearing types for years.Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.
In order to meet the needs of the design engineers, there are three different materials for the cages—- polyamide, steel and brass. For polyamide cages, it features high elasticity, light weight and quiet running from good damping. Bearings with this cage carry the designation suffix ETN, e.g. NU 205ETN. A pressed steel cage is available for many bearings, mainly as an alternative to the polyamide cage, and such bearings are identified by the designation suffix E, e.g. 310E. As for the brass cage, the advantage includes very high strength, suitable for very high speed, accelerations, high temperature and high endurance limit. The bearing with this cage is identified by the designation suffix EM, e.g. NU 207EM.
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.
We have plenty available bearings for practically any running precision requirement and application speed: our bearings come in different Abec tolerance grades 1-9, internal clearances vary from C2 to C4, and several different cage designs including J-type, W-type, RJ-type, TW-type, and more. The deep groove bearing 6000 series can also be supplied with a full complement of balls as a filler notch design, which is with filling slots have a filling slot on the inner race as well as on the outer race, so that more and larger balls can be accommodated than with standard deep groove ball bearings. Its structure is simple, it consists of inner and outer rings with deep symmetrical ball race, separator and complement of balls, and it can be easy to operate. The big difference between the full complement style and standard deep groove ball bearing lies in the retainer, the former is without retainer in order to add more balls.
This 6000-NR series deep groove ball bearing with snap ring is for usage in applications that involve combined radial and axial loads and a need for high running accuracy and stiffness at high rotational speeds. The deep groove ball bearings with snap ring are mainly used in clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile machines, among others. This heavy 6400 series single row deep groove ball bearing with a sheet steel cage supports radial loads and axial loads in both directions. It is also suitable for high speed applications. We have different clearance options available, for example, bearings with “C3” in the part number have a C3 radial internal clearance designation to indicate that the radial slack between the inner and outer rings is greater than the standard CN (normal) clearance. It allows for thermal expansion as the bearing supports radial loads and its balls, operating in the deep raceway geometry, reduce rotational friction.
Bearings can be seen everywhere in our lives and work, such as household appliances, garden tools and transportation. For different application scenarios, different bearings assume different roles. The bearings commonly used in vehicles represented by motorcycles and automobiles are starter motor bearings, crankshaft bearings, gearbox bearings and wheel hub bearings. According to the operating conditions of the starter motor, specific requirements are put forward for the bearing’s ability to withstand intermittent impact loads, and at the same time, it must have good dust-proof performance and select a reasonable internal bearing clearance.

Functionally similar to the 6200 series, the 6300 series medium ball bearings is produced with a larger ball complement and heavier races allowing greater radial, thrust and combined load capacity for a given bore size. This series is also capable of withstanding heavy shock loads. The 6300 series is available in open, sealed or shielded configurations. It is also available in stainless steel. Deep groove ball bearings 6300 types have low frictional resistance and high rotational speed and can be used to withstand radial loads or combined radial and axial loads as well as axial loads. The 6300 series deep groove ball structure is also divided into a sealed and open structure, the open type refers to the bearing without sealing structure, and the sealed deep groove ball is divided into a dust-proof seal and an oil proof seal. The dust seal cover material is stamped from steel and can easily prevent dust from entering the bearing race. The oil-proof type is a contact type oil seal, which can effectively prevent the grease in the bearing from overflowing.
