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.

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.

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.

In office automation tools, the office environment requires bearings to have good features such as low noise, high temperature resistance, and low starting torque. The copier also puts forward higher requirements on the electrical conductivity of the bearing. Because these bearings are usually miniature bearings, and most of them are thin-walled series, and some require flanged design, higher requirements are placed on the manufacturing process and equipment accuracy. In medical equipment, low rotational torque, low noise, and good flexibility are the basic requirements for bearings, and the safety characteristics of bearing materials, the safety characteristics of bearing grease, the anti-rust performance of bearings, and the service life of bearings are all under consideration. In the range. Find additional information on https://www.jnsnbearing.com/.

Deep groove ball bearings can be used in skateboard, gearboxes, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, roller shoes, yo-yo, etc. The deep groove ball bearing 6300NR series consists of an inner and an outer ring, a set of balls with cage and usually a layer of load-bearing lubricant, also it’s optional for open, covers or seals. The 6300NR series deep groove ball bearing has a single-row deep-groove geometry for high speeds and supporting both radial and axial loads. Balls separated by steel cages permit high-speed operation. Bearings with a locating snap ring can be fit into the housing easily, as the locating snap ring facilitates axial positioning and holds the bearing in place. This type of bearing is mainly used for pure radial loads, but also can stand radial load while small axial load. Deep groove ball bearing friction coefficient is small, but limiting speed is high.

The company has rich experience in the industry of bearing production and export. We focus on not only the domestic market, but also the international market. Moreover we integrate R&D, production and export of bearings. We constantly strive for research and innovation development, adhere to the concept of “survival of high quality”, and provide excellent service for customers. Our employees receive professional training. Our competence to work out a proposal that springs a “before vs after” clear your worries. Our concept of “ survival of high quality” urges us to attach great importance to our products quality and price, thus we have absolute strengths on them.

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 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.
