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. BK, and BK-RS Series – Drawn cup needle roller bearing, One end closed for shaft ends, cage guided, with/without seals, Metric dimensional. NCS Series – Needle roller bearings that have inch dimensions precision ground raceways with ribs, without Inner Rings, cage guided rollers, with/without Seals. NK Series – Needle roller bearings that have metric dimensions, precision ground raceways with ribs, without Inner Rings, cage guided rollers, with/without Seals.
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 drawn cup roller clutches bearings HF style comprise thin-walled, drawn outer cups with a series of ramps on the inside diameter, steel cages and needle rollers, which serve as clamping elements. Steel or plastic springs hold the needle rollers in their clamped position. Drawn cup roller clutches can transmit high torques in one direction and are particularly compact in a radial direction. The roller clutches are available with and without support bearing arrangements.
Deep Groove Ball Bearings (DGBB) are the most common form of rolling bearings and are used in a variety of applications; particularly those where high speeds and low power loss are required. DGBB can handle not only radial forces, but also moderate axial loads in both directions. They are easy to install and can be deployed in a variety of configurations. Our deep groove ball bearings deliver reliable performance in a wide range of applications and conditions. With super-finished raceways and controlled geometries, our premium design helps ensure consistent quality. Our portfolio includes standard, thin section, narrow, wide and miniature and extra-small deep groove ball bearings that span 3 mm to 400 mm bore sizes. Also there’re several different material options for the bearings, such as chrome steel, stainless steel, hybrid ceramic and etc. The extended product line includes a complete offering of open, shields, seals and snap ring combinations.
The deep groove ball bearings are widely used in household appliances, toys, bicycles, pumps, skateboard, electric power tools, gearbox, car motors and other fields. Thin-walled deep groove ball bearing is with thin width or thin height size of deep groove ball bearing. And the thin wall ball bearings are different from conventional deep groove ball bearings in that cross-section of each series are designed to be a fixed size, which do not increase as an inner diameter increased. The 6700 series bearings are a thin section bearing and are single row deep groove ball bearing, and the use of small outer diameter steel balls can reduce friction significantly. Thin section ball bearings have a bearing inner diameter to outer diameter ratio that is less than a specified value. The thin wall metric dimensional series deep groove ball bearing has the characteristics of small size, light weight and low friction. It is in a small size and light weight, has space saving, weight reduced and external dimensions reduced, low friction and having good rotation accuracy.
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. Read more info on 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.
