NAO Series – Radial Needle Roller Bearings that have metric dimensions without ribs, with Inner Rings, and with/without Seals. NKI Series – Needle roller bearings that have metric dimensions, with Inner Rings, cage guided rollers, precision ground raceways with ribs, with/without Seals. NKIS Series – Needle roller bearings that have metric dimensions, larger outside diameter and heavier load capacity (vs. NKI Series), with Inner Rings, cage guided rollers, precision ground raceways with ribs, with/without Seals. RNAO Series – Radial Needle Roller Bearings that have metric dimensions without ribs, without Inner Rings, and with/without Seals. N Series – Bearings of N design are single row cylindrical roller bearing and have two 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 N Series bearings have virtually no thrust capacity. NU Series – Are single row cylindrical roller 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 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.
Drawn cup roller clutches can be used in various applications such as indexing clutches, back-stopping clutches and overrunning clutches. The standard F series drawn cup needle roller bearing is open- end drawn cup needle roller bearing with full of needles, which consists of an outer ring made of carefully selected alloy steel that is surface hardened after precision pressing, rollers made of vacuum degassed bearing steel that is through-hardened and given a grinding finish, and a cage that accurately guides the rollers on the pitch diameter. Moreover, the surface coatings available include nickel plating and black oxide coating.
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.
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.
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.

F6000 series bearings are very similar to normal grooved ball bearings, and the only difference is that this type ball bearings have a flange on the outer ring, which can be very useful for mounting the bearings in through holes or axial location. Flanged deep groove ball bearings F6000 series are available in open, shielded and sealed options. The shields and sealed options provide protection to prevent debris and dust getting into the bearing, while at the same time retaining the grease to ensure good lubrication and a long service life. Metric sized deep groove radial flanged ball bearings can bear heavy radial loads and moderate thrust loads in both directions. These bearings are made to the same sizes as standard bearings 6000 series. They also have a flange, which allows flush fitting into housings up to the flange shoulder. This type of bearing is often used on steel tracks to act as both a guide and a support. Deep groove ball bearings are widely used bearings. They use uninterrupted raceways, making them an excellent choice for radial loads. This design achieves precise tolerances even at high speeds.
