Cylindrical roller bearing manufacturer in China: 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. 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. Read more information on needle bearing manufacturer.
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.
Cylindrical roller bearing is the most simple type of bearing in roller bearing. It has line contact between the rollers and raceway, therefore radial load capability is high, making this bearing superior in regards to its ability to withstand heavy loads and impact loads. Moreover, mounting and removing is easy due to the inner ring and outer ring being separable. The outer ring of the N type cylindrical roller bearing has no ribs, and the inner ring has ribs on both sides. 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.
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.

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.
