Premium needle roller bearing manufacturer and supplier: 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. NA 48 Series – Needle roller bearings that have metric dimensions, with Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 48 Dimensional Series. NA 49 Series – Needle roller bearings that have metric dimensions, with Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 49 Dimensional Series. NA 69 Series – Needle roller bearings that have metric dimensions, with Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 69 Dimensional Series.

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.
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.
In office automation tools, the office environment requires bearings to have good features such as low noise, high temperature resistance, and low starting torque. The copier also puts forward higher requirements on the electrical conductivity of the bearing. Because these bearings are usually miniature bearings, and most of them are thin-walled series, and some require flanged design, higher requirements are placed on the manufacturing process and equipment accuracy. In medical equipment, low rotational torque, low noise, and good flexibility are the basic requirements for bearings, and the safety characteristics of bearing materials, the safety characteristics of bearing grease, the anti-rust performance of bearings, and the service life of bearings are all under consideration. In the range. See even more 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.
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.
