Depending on the series as defined below a number of cylindrical bearings have no ribs on either the inner or outer ring, so the rings can move axially relative to each other which can be used as free-end bearings. Pressed steel (with or without tins or fins) or machined brass cages are generally used, but sometimes molded polyamide cages are also available depending on the application. Cylindrical Roller Bearings are also available without cages with a full complement of rollers. This allows even higher loads but at the expense of speed. 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.
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.
JnSn needle roller bearing manufacturer have a high capacity for load carrying. They can also operate at high speeds with slim designs that allow use with limited radial space. Our HK Style needle roller bearings are available with or without an outer ring, and drawn cup needle roller bearings generally do not have an inner ring. The drawn cup style provides high load capacity along with large grease reservoirs. The under rollers are available in various diameters, and the hk bearings are capable of a range of dynamic and static loads. Bearings are also available with seals in inch or metric measurements. Needle roller bearings standard are suitable for the automotive industry parts such as rocker arm pivots, compressors, transmissions, and drive shafts.
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.
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.
The wheel hub bearing has a high speed and a large force, which requires the use of suitable grease, and the internal design of the clearance is relatively large, which puts forward higher requirements on the production of raw materials. The force and working conditions of automobile bearings are more complicated than those of motorcycles. For example, the bearing of the automobile condensing fan motor should take into account the continuous working condition of the motor under high temperature conditions and so on. In garden tools represented by lawn mowers, gearboxes have extremely high requirements for the sealing of the bearings, neither allowing the grease in the box to penetrate into the bearings nor leak the grease. Due to the higher pressure in the gearbox, the bearing is also required to have a special pressure relief function. Discover more details on 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.
