Single row cylindrical roller bearings are also manufactured with snap ring grooves on the outer rings. This design simplifies the bearing joint as the bearings are located into the housing by means of the snap rings. The snap ring groove and snap rings are in accordance with IS0 464. There are different types designated NU, NJ, NUP, N, NF, RN for single-row bearings, NNU, NN for double-row bearings depending on the design or absence of side ribs, and SL series for four-row bearings. Our cylindrical bearing rollers come in the following series with various cage designs and Metric dimensions. NAO Series – Radial Needle Roller Bearings that have metric dimensions without ribs, with Inner Rings, and with/without Seals. NKI Series – Needle roller bearings that have metric dimensions, with Inner Rings, cage guided rollers, precision ground raceways with ribs, with/without Seals. NKIS Series – Needle roller bearings that have metric dimensions, larger outside diameter and heavier load capacity (vs. NKI Series), with Inner Rings, cage guided rollers, precision ground raceways with ribs, with/without Seals. RNAO Series – Radial Needle Roller Bearings that have metric dimensions without ribs, without Inner Rings, and with/without Seals.

NU Series cylindrical roller bearings are single row bearings and have two 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 NU Series bearings have no virtually thrust capacity. NJ cylindrical roller bearing tends to posses a collar on its inner race at one end. This collar is normally positioned in such a way that it transfers the axial load in the shaft to the rolling elements. This is the type of cylindrical roller bearing which is capable of carrying axial load to a certain extent. The extent of the axial load that can be carried by the bearing is dependent only on the specific bearing.

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.

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.

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 additional info on jnsnbearing.com.

Deep groove ball bearings can be used in generators, small motors, electric fans, power tools, vacuum cleaners, conveyor, packaging machine, drilling machine, conveyor, variable, washing machine, optical instruments and so on. Single row radial ball bearing 6200 series are available in Metric and Inches, and there are three seal types reachable– rubber seals, metal shields, or just open. Also we have several material options for the bearing, plastic, chrome steel, stainless steel, ceramic, carbon steel and etc. This series features deep-honed raceways resulting in a perfectly balanced bearing. For 6200 series of deep groove ball bearing, its structure is simple and easy to use, it consists of four elements that including inner ring, outer ring, cage that holds balls and ball bearing. It is mainly used to bear radial load, but when it increases the radial clearance of the bearing, it has certain angular contact ball bearing performance and can withstand combined radial and axial loads. It can also be used to withstand pure axial loads when the rotational speed is high and thrust ball bearings are not suitable. Compared with other types of bearings of the same size as deep groove ball bearings, these bearings have a small coefficient of friction and a high limit speed.
