Needle roller bearing manufacturing factory 2024

Needle bearing supplier factory in China: 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. 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.

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.

Single-row cylindrical roller bearings with a cage comprising cylindrical rollers caged between a solid outer and inner ring. These bearings have a high level of rigidity, can support heavy radial loads and are suitable for high speeds. The inner and outer rings can be fitted separately, making installation and removal a simple process. Single-row cylindrical roller bearings are available in various designs. The most common models are NU, N, NJ and NUP. The main difference is the configuration of the ribs.

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. Read extra information at jnsnbearing.com.

Deep groove ball bearings can be used in skateboard, gearboxes, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, roller shoes, yo-yo, etc. The deep groove ball bearing 6300NR series consists of an inner and an outer ring, a set of balls with cage and usually a layer of load-bearing lubricant, also it’s optional for open, covers or seals. The 6300NR series deep groove ball bearing has a single-row deep-groove geometry for high speeds and supporting both radial and axial loads. Balls separated by steel cages permit high-speed operation. Bearings with a locating snap ring can be fit into the housing easily, as the locating snap ring facilitates axial positioning and holds the bearing in place. This type of bearing is mainly used for pure radial loads, but also can stand radial load while small axial load. Deep groove ball bearing friction coefficient is small, but limiting speed is high.

JNSN Bearing supplier, manufacturer is specialized in producing different types of bearings, sunch as deep groove ball bearings, self-aligning ball bearings, spherical roller bearings, single row tapered roller bearings, inch tapered bearings, automotive bearings, bearing joints, etc. The annual production capability is more than 960 million units. We have solid teamwork and systematic management to offer one-stop service. We’ll monitor every steps during production, then deliver order timely, and the client just need to wait to receive the items. We’re always here ready to listen to client’s needs and provide economical solutions, suggestions or other helps for the client.

These bearings have a higher radial load capacity than deep groove ball bearings without filling slots, though their axial load capacity is lower. They cannot be used at speeds as high as bearings without filling slots. Both open (unsealed) and sealed versions of the single-row deep groove ball bearings with filling slots are available. They are also available with a ring groove on the outer race and with (NR) or without (N) a matching locking ring. The full complement deep groove ball bearings are widely used in aerospace engineering, metal cutting machine tools, steel processing equipment,paper making machinery, cement machinery, environmental protection equipment, agriculture, compressors, motors and generators, construction and so on.

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.
