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.
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.
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. See additional details 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 adheres to the concept of “customer-oriented, standard-oriented, and profit-assisted”, and has established a good reputation in the bearing industry. Its products are sold to more than ten countries such as the United States, the United Kingdom, Sweden, and Germany. With excellent and stable quality instead of imports, it has won unanimous praise from customers at home and abroad. Company profile – HangZhou Jnsn Bearing Imp& Exp Co., Ltd is a company specializing in designing, manufacturing, trading of a wide range of bearings. Core technical members is active in developing popular bearing product and try fast development of new products, we always aim at quality first. OEM service is also available, we accept to customize based on the drawing or original sample.
We have plenty available bearings for practically any running precision requirement and application speed: our bearings come in different Abec tolerance grades 1-9, internal clearances vary from C2 to C4, and several different cage designs including J-type, W-type, RJ-type, TW-type, and more. The deep groove bearing 6000 series can also be supplied with a full complement of balls as a filler notch design, which is with filling slots have a filling slot on the inner race as well as on the outer race, so that more and larger balls can be accommodated than with standard deep groove ball bearings. Its structure is simple, it consists of inner and outer rings with deep symmetrical ball race, separator and complement of balls, and it can be easy to operate. The big difference between the full complement style and standard deep groove ball bearing lies in the retainer, the former is without retainer in order to add more balls.
The diversity of thin wall ball bearings makes them suitable for a wide range of applications, such as aerospace, semiconductor processing equipment, robotics, medical equipment and other fields. F6700 series is a deep groove ball bearing with a flange on one side of the outer ring. When using this bearing, it is not necessary to provide a step on the inner bore of the housing, so it is possible to process the through hole with high accuracy. Since this bearing is attached to the end face of the housing as a standard, it is necessary to machine the right angle of the housing end face with high accuracy. Single-row flanged deep groove ball bearings F6700 series are available in open and sealed designs. They are designed for high to very high speeds and can accommodate radial as well as axial forces. Flanged bearings are recommended when housing designs cannot accommodate full bearing width, or where the quality of the housing bore is a concern. Moreover, because of their simple design, low operating temperature, and low friction, flanged deep groove ball bearings have a longer expected shelf life than other bearings. They do not require additional lubrication after installation, which also means less maintenance downtime.
