NNU Series – Are double row cylindrical roller bearing manufacturers and have three fixed ribs on the outer ring and one smooth inner ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. Therefore, NU Series rolling bearings are used in non-locating bearing units. Also, the NNU Series bearings have no virtually thrust capacity. RNA 48 Series – Needle roller bearings that have metric dimensions, without Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 48 Dimensional Series. RNA 49 Series – Needle roller bearings that have metric dimensions, without Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 49 Dimensional Series. RNA 69 Series – Needle roller bearings that have metric dimensions, without Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 69 Dimensional Series.
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 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.
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.
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.
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.
