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. NA 48 Series - Needle roller bearings that have metric dimensions, with Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 48 Dimensional Series. NA 49 Series - Needle roller bearings that have metric dimensions, with Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 49 Dimensional Series. NA 69 Series - Needle roller bearings that have metric dimensions, with Inner Rings, with/without Seals, precision ground raceways with ribs, cage guided rollers, and ISO 69 Dimensional Series.
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 correct form and dimensional accuracy of outer ring of drawn cup needle roller bearing is achieved only by press fitting into proper housing with appropriate interference. Therefore, roller inscribed circle diameter is measured after press fitted into a standard ring gauge. Full complement drawn cup needle bearings F type has a drawn outer shell that serves as a raceway for the maximum number of rollers. This combines high radial load-carrying capability with low cost. And this series is ideal for applications where the shaft must be removed for service, which is also easy and convenient for assembly. The drawn cup needle roller bearings are commonly used in transmissions, alternators, A/C compressors, pumps, outboard engines, power tools, tractors, door closers etc.
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 6400 series deep groove ball bearing is rated heavy, making it applicable for usage with heavy radial loads and moderate axial loads. It can be used to a maximum operating temperature of 120 degrees C/248 degrees F. The inner and outer rings and balls are made of a low-alloy, through-hardened chromium steel for durability, heat tolerance, and resistance to deformity under heavy loads, and the sheet steel cage prevents the balls from coming into contact with each other during use, reducing friction, vibration, and noise. It has an open design for lubricating the bearing in place. This deep groove ball bearing series is for usage in various applications such as transmissions, motors, pumps, bicycles, machine tools, generators, textile machinery, agriculture machinery and inline skates, among others.
In office automation tools, the office environment requires bearings to have good features such as low noise, high temperature resistance, and low starting torque. The copier also puts forward higher requirements on the electrical conductivity of the bearing. Because these bearings are usually miniature bearings, and most of them are thin-walled series, and some require flanged design, higher requirements are placed on the manufacturing process and equipment accuracy. In medical equipment, low rotational torque, low noise, and good flexibility are the basic requirements for bearings, and the safety characteristics of bearing materials, the safety characteristics of bearing grease, the anti-rust performance of bearings, and the service life of bearings are all under consideration. In the range. Discover additional details at jnsnbearing.com.
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.
