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. 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.
Cylindrical roller bearing is the most simple type of bearing in roller bearing. It has line contact between the rollers and raceway, therefore radial load capability is high, making this bearing superior in regards to its ability to withstand heavy loads and impact loads. Moreover, mounting and removing is easy due to the inner ring and outer ring being separable. The outer ring of the N type cylindrical roller bearing has no ribs, and the inner ring has ribs on both sides. 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.
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 have a higher radial load capacity than deep groove ball bearings without filling slots, though their axial load capacity is lower. They cannot be used at speeds as high as bearings without filling slots. Both open (unsealed) and sealed versions of the single-row deep groove ball bearings with filling slots are available. They are also available with a ring groove on the outer race and with (NR) or without (N) a matching locking ring. The full complement deep groove ball bearings are widely used in aerospace engineering, metal cutting machine tools, steel processing equipment,paper making machinery, cement machinery, environmental protection equipment, agriculture, compressors, motors and generators, construction and so on.
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.
Bearings can be seen everywhere in our lives and work, such as household appliances, garden tools and transportation. For different application scenarios, different bearings assume different roles. The bearings commonly used in vehicles represented by motorcycles and automobiles are starter motor bearings, crankshaft bearings, gearbox bearings and wheel hub bearings. According to the operating conditions of the starter motor, specific requirements are put forward for the bearing’s ability to withstand intermittent impact loads, and at the same time, it must have good dust-proof performance and select a reasonable internal bearing clearance.

F6000 series bearings are very similar to normal grooved ball bearings, and the only difference is that this type ball bearings have a flange on the outer ring, which can be very useful for mounting the bearings in through holes or axial location. Flanged deep groove ball bearings F6000 series are available in open, shielded and sealed options. The shields and sealed options provide protection to prevent debris and dust getting into the bearing, while at the same time retaining the grease to ensure good lubrication and a long service life. Metric sized deep groove radial flanged ball bearings can bear heavy radial loads and moderate thrust loads in both directions. These bearings are made to the same sizes as standard bearings 6000 series. They also have a flange, which allows flush fitting into housings up to the flange shoulder. This type of bearing is often used on steel tracks to act as both a guide and a support. Deep groove ball bearings are widely used bearings. They use uninterrupted raceways, making them an excellent choice for radial loads. This design achieves precise tolerances even at high speeds.
