Spherical rollers - 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.

Impact rollers are available with rubber or polyurethane discs FRAS discs are available for explosive environments Dimensions: Roller diameter 63,5 mm (2-1/2” to 10”) Shaft diameter up to 80 mm (3-1/8”) Ball and spherical roller bearings

AViTEQ Unbalance exciters are designed for producing linear motion for medium and large size vibrating machines operating in many industrial processes. The design is engineered for safe operation in continual operation with 100% centrifugal force. In order to archieve higher working moments it is possible to use number of exciters parallel in line. Advantages and benefits powerful drive for higher working moments and wide performance range extremely durable smooth running low maintenance in continual operation economical and long service life low noise level operation Construction and operation mode The AViTEQ unbalance exciters are made ​​of low vibration cast housing. Two shafts mounted in four spherical roller bearings are synchronized by two gears . The mounted on the shaft ends and synchronous forced unbalanced weights are driven by an external drive and produce unidirectional vibrations . The regulation of the static moment can be carried out by some additional weights . Key fi

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.

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...

In addition to precision deep groove ball bearings, ROS also employs self-aligning ball bearings and spherical roller bearings for its heavy load rollers with internal bearings. In addition to a selection of different tube and shaft designs, powered rollers are also available for use.
