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, and HK-RS Series – Drawn cup needle roller bearing, Open ends for through shafts, cage guided, with/without seals, Metric dimensional. HF Series–It is made of pressed outer ring and plastic holder; the holder can be installed with plastic reed or the stainless steel reed to guide the needle rollers, bevel race way and needle rollers can be treated as locking device. BCE and BCE-P Series – Drawn cup needle roller bearing, One end closed for shaft ends, cage guided, with/without seals, Inch dimensional
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 HF series is composed of one-way bearings, and they are consisting of a drawn cup roller clutch with a single or multiple rollers. The models of this series come with different bore sizes that ranges from 6 mm up to 35 mm. The drawn cup needle roller clutch of these bearings has a small radial section height and is also popular with the name of One Way Bearing or Anti-Reverse Bearing. Furthermore, these one way bearings are specifically designed for the transmission of torque between the shaft and housing in one direction. In addition, bearings with plastic springs have the suffix KF, and suffix R refers to knurled outside surface.
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.
The wheel hub bearing has a high speed and a large force, which requires the use of suitable grease, and the internal design of the clearance is relatively large, which puts forward higher requirements on the production of raw materials. The force and working conditions of automobile bearings are more complicated than those of motorcycles. For example, the bearing of the automobile condensing fan motor should take into account the continuous working condition of the motor under high temperature conditions and so on. In garden tools represented by lawn mowers, gearboxes have extremely high requirements for the sealing of the bearings, neither allowing the grease in the box to penetrate into the bearings nor leak the grease. Due to the higher pressure in the gearbox, the bearing is also required to have a special pressure relief function. Find even more information at https://www.jnsnbearing.com/.
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.
