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. 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.
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.
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.
Deep Groove Ball Bearings (DGBB) are the most common form of rolling bearings and are used in a variety of applications; particularly those where high speeds and low power loss are required. DGBB can handle not only radial forces, but also moderate axial loads in both directions. They are easy to install and can be deployed in a variety of configurations. Our deep groove ball bearings deliver reliable performance in a wide range of applications and conditions. With super-finished raceways and controlled geometries, our premium design helps ensure consistent quality. Our portfolio includes standard, thin section, narrow, wide and miniature and extra-small deep groove ball bearings that span 3 mm to 400 mm bore sizes. Also there’re several different material options for the bearings, such as chrome steel, stainless steel, hybrid ceramic and etc. The extended product line includes a complete offering of open, shields, seals and snap ring combinations.
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.
