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.
We have plenty available bearings for practically any running precision requirement and application speed: our bearings come in different Abec tolerance grades 1-9, internal clearances vary from C2 to C4, and several different cage designs including J-type, W-type, RJ-type, TW-type, and more. The deep groove bearing 6000 series can also be supplied with a full complement of balls as a filler notch design, which is with filling slots have a filling slot on the inner race as well as on the outer race, so that more and larger balls can be accommodated than with standard deep groove ball bearings. Its structure is simple, it consists of inner and outer rings with deep symmetrical ball race, separator and complement of balls, and it can be easy to operate. The big difference between the full complement style and standard deep groove ball bearing lies in the retainer, the former is without retainer in order to add more balls.
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.
Jnsn wholesale bearing suppliers parts at great pricing. Fast free, worldwide shipping. Great warranties. Volume discounts. Technical Drawings. Lowest Pricing. Standard precision bearings generally use stamped steel cages. Extra precision bearings, on the other hand, use cages made from stainless steel, bronze, or phenolic— Cages made from these materials offer higher speeds and better loading capabilities.Precision ball bearings are used for high precision applications in a variety of markets, including aerospace, health, machine tool, robotics and general industry.Precision types of bearing are used in critical aeronautical bearings, guidance system balls for space and military applications, valves, automotive bearings, cosmetics, and other applications where higher precision is required.

Functionally similar to the 6200 series, the 6300 series medium ball bearings is produced with a larger ball complement and heavier races allowing greater radial, thrust and combined load capacity for a given bore size. This series is also capable of withstanding heavy shock loads. The 6300 series is available in open, sealed or shielded configurations. It is also available in stainless steel. Deep groove ball bearings 6300 types have low frictional resistance and high rotational speed and can be used to withstand radial loads or combined radial and axial loads as well as axial loads. The 6300 series deep groove ball structure is also divided into a sealed and open structure, the open type refers to the bearing without sealing structure, and the sealed deep groove ball is divided into a dust-proof seal and an oil proof seal. The dust seal cover material is stamped from steel and can easily prevent dust from entering the bearing race. The oil-proof type is a contact type oil seal, which can effectively prevent the grease in the bearing from overflowing.
