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. 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.

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 deep groove ball bearings 6000NR series are equipped with groove and circlip in outer ring. The snap ring is made from a spring steel material and fits into an annular groove around the outside of the bearing which is offset to one side. And the snap ring groove can simplify arrangement design as the bearings can be axially located in the housing by a snap (or retaining) ring, saving space. These deep groove ball bearing types are available in open, shields or sealed option. The bearings are with metal shields or contact seals offering some protection against mechanical damage and serving to retain the lubricant in the sealed for life bearing. The deep groove ball bearings 6000NR series have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.

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.

Single row deep groove ball bearings 6200 series with a ring groove can simplify the installation technically, as the bearings can be inserted with a locking ring into the housing in the axial direction. The nap rings are used on the outside edge. This saves time and space. The appropriate locking rings can be supplied separately (supplement N) or pre-assembled on the bearing (supplement NR). Both open (unsealed) and steel shields or rubber seals versions of the single-row deep groove ball bearings are available, and they are all pre-lubricated with grease. While many different retainers are available, ball bearings use standard cages of pressed steel, as well as machined, brass cages for high-speed applications. Deep groove radial ball bearings are used to transmit loads from rotating parts to housings with minimum friction loss. This will be obtained by a high hardness, minimizing the deformation of the bearing elements. Additional design measures ensure an undisturbed free rolling action, the measures includes the radial clearance, materials and precision.
