NAO Series – Radial Needle Roller Bearings that have metric dimensions without ribs, with Inner Rings, and with/without Seals. NKI Series – Needle roller bearings that have metric dimensions, with Inner Rings, cage guided rollers, precision ground raceways with ribs, with/without Seals. NKIS Series – Needle roller bearings that have metric dimensions, larger outside diameter and heavier load capacity (vs. NKI Series), with Inner Rings, cage guided rollers, precision ground raceways with ribs, with/without Seals. RNAO Series – Radial Needle Roller Bearings that have metric dimensions without ribs, without Inner Rings, and with/without Seals. 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.

Single-row cylindrical roller bearings with a cage comprising cylindrical rollers caged between a solid outer and inner ring. These bearings have a high level of rigidity, can support heavy radial loads and are suitable for high speeds. The inner and outer rings can be fitted separately, making installation and removal a simple process. Single-row cylindrical roller bearings are available in various designs. The most common models are NU, N, NJ and NUP. The main difference is the configuration of the ribs.

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.

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 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.

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.
