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. NA 48 Series – Needle roller bearings that have metric dimensions, with Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 48 Dimensional Series. NA 49 Series – Needle roller bearings that have metric dimensions, with Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 49 Dimensional Series. NA 69 Series – Needle roller bearings that have metric dimensions, with Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 69 Dimensional Series.
These bearings are separable bearings, and convenient to be mounted and dismounted. They are designed as types of single, double and multiple rows among which the single row cylindrical roller bearings are most applicable. Normally these bearings can accommodate radial load only, none but single row bearings with ribs both on inner and outer rings can carry lighter constant axial load. Application – They are mainly used in large and medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, lifting and transport machinery, etc. Cylindrical roller bearings are the right choice for high speeds and heavy radial loads. They are produced in different inner ring designs for easy dismounting.
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.
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.
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.
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.
