Cylindrical roller bearing supplier factory by JnsnBearing: 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. 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.

Its main features are low cross-section height and high load carrying capacity. Mainly used for bearing arrangements that are compact, inexpensive, and the bore of the bearing housing cannot be used as the raceway for the needle roller cage assembly. The bearing and bearing housing must be installed in an interference fit. If the axial positioning function such as the box shoulder and the stop ring can be omitted, the inner hole of the bearing housing can be made extremely simple and economical. The drawn cup needle roller bearings mounted on the shaft end are open on both sides and closed on one side. The base end face of the closed stamped outer ring can withstand small axial guiding forces.
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. Find additional information at https://www.jnsnbearing.com/.
Single row deep groove ball bearings 6200 series with a ring groove can simplify the installation technically, as the bearings can be inserted with a locking ring into the housing in the axial direction. The nap rings are used on the outside edge. This saves time and space. The appropriate locking rings can be supplied separately (supplement N) or pre-assembled on the bearing (supplement NR). Both open (unsealed) and steel shields or rubber seals versions of the single-row deep groove ball bearings are available, and they are all pre-lubricated with grease. While many different retainers are available, ball bearings use standard cages of pressed steel, as well as machined, brass cages for high-speed applications. Deep groove radial ball bearings are used to transmit loads from rotating parts to housings with minimum friction loss. This will be obtained by a high hardness, minimizing the deformation of the bearing elements. Additional design measures ensure an undisturbed free rolling action, the measures includes the radial clearance, materials and precision.
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.
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.
