Top cylindrical roller bearing provider manufacturer: 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. Needle roller bearings are essentially cylindrical roller bearings except that their cylindrical rollers have a length 3 to 10 times their diameter (versus a length less than 3 times their diameter). Needle bearings are also essentially bearings that utilize small & cylindric rollers. Therefore, the ratio of the bearing outside diameter to the inscribed circle diameter is small, and they have a rather high radial load capacity. Even though they have a low cross section, needle roller bearings have a high radial load capacity and are exceptionally apt for bearing applications where radial space is limited.

HK Style Standard Needle Roller Bearings are commonly referred to as drawn cup needle bearings due to the shape of the bearing housing. Drawn cup needle roller bearings with open ends are needle roller bearings with a very small radial section height. They comprise thrust needle roller bearing, thin-walled, drawn cup outer rings and needle roller and cage assemblies which together form a complete unit. This needle roller bearing types use small, cylindrical rollers which are long and narrow. These bearings allow for a large surface area to be in contact with the outer race, and are much more compact than cylindrical rollers.
NU Series cylindrical roller bearings are single row 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 cylindrical roller bearing tends to posses a collar on its inner race at one end. This collar is normally positioned in such a way that it transfers the axial load in the shaft to the rolling elements. This is the type of cylindrical roller bearing which is capable of carrying axial load to a certain extent. The extent of the axial load that can be carried by the bearing is dependent only on the specific bearing.
In addition to the above-mentioned industries, in industrial motors, the bearings used are usually required to withstand heavy loads, and the bearing environment is relatively harsh. Bearings in motors such as household appliances such as air conditioners and washing machines have very strict requirements for low noise and high rotation accuracy. Jnsn bearing company is a professional best bearing manufacturer integrating bearing design, research and development, manufacturing, and trade. It can also provide ceramic, high-temperature, low-temperature, low-friction and other special-purpose types of bearings. The main products include best ball bearing, linear bearings, needle roller bearings, angular contact bearings, thin-walled bearings, tapered roller bearings, joint bearings, etc. Discover more details on jnsnbearing.com.
Deep groove ball bearings can be used in generators, small motors, electric fans, power tools, vacuum cleaners, conveyor, packaging machine, drilling machine, conveyor, variable, washing machine, optical instruments and so on. Single row radial ball bearing 6200 series are available in Metric and Inches, and there are three seal types reachable– rubber seals, metal shields, or just open. Also we have several material options for the bearing, plastic, chrome steel, stainless steel, ceramic, carbon steel and etc. This series features deep-honed raceways resulting in a perfectly balanced bearing. For 6200 series of deep groove ball bearing, its structure is simple and easy to use, it consists of four elements that including inner ring, outer ring, cage that holds balls and ball bearing. It is mainly used to bear radial load, but when it increases the radial clearance of the bearing, it has certain angular contact ball bearing performance and can withstand combined radial and axial loads. It can also be used to withstand pure axial loads when the rotational speed is high and thrust ball bearings are not suitable. Compared with other types of bearings of the same size as deep groove ball bearings, these bearings have a small coefficient of friction and a high limit speed.
Our own manufacturing factory is specialized in producing 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.

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 6400 series deep groove ball bearing is rated heavy, making it applicable for usage with heavy radial loads and moderate axial loads. It can be used to a maximum operating temperature of 120 degrees C/248 degrees F. The inner and outer rings and balls are made of a low-alloy, through-hardened chromium steel for durability, heat tolerance, and resistance to deformity under heavy loads, and the sheet steel cage prevents the balls from coming into contact with each other during use, reducing friction, vibration, and noise. It has an open design for lubricating the bearing in place. This deep groove ball bearing series is for usage in various applications such as transmissions, motors, pumps, bicycles, machine tools, generators, textile machinery, agriculture machinery and inline skates, among others.
