Spherical roller bearings - Import export

With decades of experience, we manufacture spherical roller bearings at KIS that can support large radial and axial forces in both directions. The perfect solution for applications that have to withstand massive loads. Due to the design of two rows of pendulum-shaped rollers in a common, hollow-ball raceway in the outer ring, our spherical roller bearings can support large radial and also axial forces. This makes them perfect for applications that have to withstand high loads and shocks and compensate for shaft bending or misalignment. In addition to conventional spherical roller bearings (which have no seal and have either a tapered or cylindrical bore), there are also application-specific variants developed for special requirements (e.g. sealed spherical roller bearings or bearings with optimised load ratings). Spherical roller bearings offer high performance and efficiency and are available in a wide range of sizes and designs.

Double row spherical roller bearings have two rows of self-aligning rollers and common spherical raceways on the outer ring. The internal construction of the bearing enables the mirrored misalignment of the rings. Spherical roller bearings can tolerate high radial loads whilst at the same time transmitting axial forces in both directions.

The unique construction of spherical roller bearings make them vital for heavy applications. Their performance is consistent even in extreme conditions, as in the case of high-stress environments and / or reduced lubrication. Spherical roller bearings can give a use life equal to twice that of traditional bearings, according to some estimates. Features of spherical roller bearings: ideal for reduced and medium speeds self-aligning and very robust able to bear radial and axial loads in both directions longer use life compared to traditional bearings excellent compensation for misalignments APPLICATIONS: Earth Moving Machinery Agricultural Machinery Fitness machines Steel working machines Marble processing machines Iron and Steel Industry Oil Industry Automatic opening systems Heavy machinery (eg machines for construction and mining) Bottling / filling carousels Steel mills Industrial transmissions Vibrating equipment / machines Vibrating sieves / vibrating screens

IKO PILLOBALLs are compact selfaligning spherical bushings which can support a large radial load and a bidirectional axial load at the same time. These bearings are available in insert type, diecast type and lubricationfree type depending on the type of sliding surface. In the insert type, a spherical inner ring makes contact with a special copper alloy bushing with superior runin properties. In the diecast type, a spherical inner ring makes direct contact with the bore surface of the body of special zinc diecast alloy. In the maintenancefree type, a spherical inner ring makes contact with a special selflubricating PTFE liner. Thus, a smooth rotational and oscillatory motion can be achieved with superior antiwear and load properties in each type. PILLOBALL Rod Ends have either a female thread in the body or a male thread on the body, so they can be easily assembled onto machines. They are used in control and link mechanisms in machine tools, textile machines

IKO Spherical Bushings are compact selfaligning spherical bushings with inner and outer rings in contact with the sphere, which can support a large radial load and a bidirectional axial load at the same time. There are many models of Spherical Bushings, but they are basically divided into steelonsteel types and maintenancefree types according to the kind of sliding surfaces. Steelonsteel Spherical Bushings have inner and outer rings of highcarbon chromium bearing steel, of which sliding surfaces are phosphatetreated and then drycoated with molybdenum disulfide (MoS2). They can, therefore, operate with low torque, and have excellent wear resistance and large load capacity. They are especially suitable for applications where there are alternate loads and shock loads. They have wide applications mainly in industrial and construction machinery. Maintenancefree Spherical Bushings consist of an outer ring which has a special PTFE liner reinforced

Bearings in these applications are subjected to very severe operating conditions. The shaking actions of vibrating equipment subjects the bearings to very heavy loads, including impact loads. Additional load is created by higher g forces generated by acceleration in the application. Bearings are higher speed operated. Furthermore, these kinds of bearings are developed to increase the lifetime of bearings in contaminated environments. KFB designs special spherical roller bearings MAC4F80 to operate under severe conditions. Special KFB spherical roller bearings for vibrating equipment are available in 22300 and 23300 series. The clearance is similar to C4, but the lower third of C4 range is eliminated for better control of the bearing clearance after mounting.

In the mining sector severe operating and environmental conditions require extremely robust bearings. Bearings for mining industry are used for bucket wheel excavators, draglines, conveyor belts, trucks, stackers, transport equipment, loaders, longwall shearers and hoists. The mining industries use many types of bearings: roller bearings, deep groove ball bearings, spherical roller bearings and tapered roller bearings. DEEP GROOVE BALL BEARINGS The mining industries use belt conveyors for transporting bulk materials. The conveyors run on idlers and a lot of them extend over many kilometers; thus the number of idlers needed may be very large. The deep groove bearings (design 2ZR and 2RS) are sealed by dust shields and seals on both sides, and filled with grease for a long service life. SPHERICAL ROLLER BEARINGS In the mining sector severe operating and environmental conditions require extremely robust bearings. Mining machinery faces some of the toughest terrains.

require high precision, large rated moving load, and high maximum rotation speed. By adopting the new technology of material processing, KFB has successfully manufactured bearings of long service life that are highly fatigue resistant and impact resistant. The types of bearings made by KFB for the metallurgical roller mills are: split bearings; unit rollers; support roller bearings; single row, double row, three row, four row cylindrical roller bearings, fully-loaded cylindrical roller bearings, spherical roller bearings. The use of split bearings appreciably facilitates assembly and repair operations compared to the use of nonsplit (conventional) bearings. It does away with the need for the disassembly and subsequent reassembly of intermediate parts and mechanisms, which is required when replacing conventional bearings. It also reduces costs and production losses. If provided with efficient cooling, reliable lubrication and proper sealing, split-bearing components can be used...

These bearings are doublerow, full complement with a low cross sectional height designed for use in sheaves. There are two types, sealed and shield type. They can withstand heavy radial loads and shock loads at comparatively lowspeed rotations, and can also withstand axial loads. It is easy to fix them axially to sheaves using the stop rings of the outer ring. The width of the inner ring is designed to be larger than that of the outer ring, so they require no spacer between sheaves. The structure is stable because the doublerow of rollers can withstand the moment loads caused by rope transition. The surfaces of these bearings are also treated to provide high corrosion resistance.

Designed to efficiently support axial and radial forces and tilting moment loads, crossed roller bearings are suitable for applications subject to high loads and speeds. Due to the special crosswise arrangement of the cylindrical rollers in crossed roller bearings, designs with two bearing positions can often be reduced to one. Due to their high rigidity and running accuracy, they offer enormous precision and are used, for example, in robotics, medical technology and lathes. Depending on the application requirements, we at KIS manufacture cross rollers in different configurations. We are happy to advise you on the optimum solution for your application.

KIS needle roller bearings are ideal for applications that require space-saving rolling bearings with high load carrying capacity. We offer needle roller bearings in both radial and axial designs as well as in combined designs. In bearing technology, cylindrical rolling elements are referred to as needles if the rolling element diameter is ≦ 6 mm and the ratio of rolling element diameter to rolling element length gives a value Dw/lw ＜ 1:3. Radial needle roller bearings are intended exclusively for use as non-locating bearings. The given axial displacement path for bearings with an inner ring allows axial movements between the shaft and the housing. If necessary, wider inner rings are available to allow larger axial displacement paths. Our combined needle bearings are characterised by particularly high precision and efficiency. By integrating both bearings into one unit, combined needle roller bearings are often easier to press in and easier to handle than individual solutions.
