RNA 48 Series – Needle roller bearings that have metric dimensions, without Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 48 Dimensional Series. RNA 49 Series – Needle roller bearings that have metric dimensions, without Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 49 Dimensional Series. RNA 69 Series – Needle roller bearings that have metric dimensions, without Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 69 Dimensional Series. 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.
The correct form and dimensional accuracy of outer ring of drawn cup needle roller bearing is achieved only by press fitting into proper housing with appropriate interference. Therefore, roller inscribed circle diameter is measured after press fitted into a standard ring gauge. Full complement drawn cup needle bearings F type has a drawn outer shell that serves as a raceway for the maximum number of rollers. This combines high radial load-carrying capability with low cost. And this series is ideal for applications where the shaft must be removed for service, which is also easy and convenient for assembly. The drawn cup needle roller bearings are commonly used in transmissions, alternators, A/C compressors, pumps, outboard engines, power tools, tractors, door closers etc.
Easy Interchange – Designed as metric bearings, our deep groove ball bearings follow ISO standards and are dimensionally interchangeable with competitor metric products. Premium Lubricants – For reduced torque and a quieter operation, premium lubricant comes standard on all sealed and shielded deep groove ball bearings. This grease has a temperature range from -29℃ to 177℃. Brass Cage Availability – Deep groove ball bearings with brass cages (available in select sizes) can deliver extra strength and durability in the most unrelenting conditions: extreme shock loads, high vibrations and high forces due to acceleration. Quiet Running for Electric Motor Quality – Deep groove ball bearings are frequently used in electric motor applications to minimize vibration and noise.
The diversity of thin wall ball bearings makes them suitable for a wide range of applications, such as aerospace, semiconductor processing equipment, robotics, medical equipment and other fields. F6700 series is a deep groove ball bearing with a flange on one side of the outer ring. When using this bearing, it is not necessary to provide a step on the inner bore of the housing, so it is possible to process the through hole with high accuracy. Since this bearing is attached to the end face of the housing as a standard, it is necessary to machine the right angle of the housing end face with high accuracy. Single-row flanged deep groove ball bearings F6700 series are available in open and sealed designs. They are designed for high to very high speeds and can accommodate radial as well as axial forces. Flanged bearings are recommended when housing designs cannot accommodate full bearing width, or where the quality of the housing bore is a concern. Moreover, because of their simple design, low operating temperature, and low friction, flanged deep groove ball bearings have a longer expected shelf life than other bearings. They do not require additional lubrication after installation, which also means less maintenance downtime.
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 even more info at https://www.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.
