Bearings- ball - Import export

Pillow block bearings, flange bearings and take-up bearing units consist of a housing with a bearing mounted in it. They are available in a variety of materials, mounting configuration and various bearing features. Each mounted unit acts as a system to position the bearing securely for reliable operation.

KFB-Clarfeld thrust ball bearings are manufactured as single and double direction models. Ball bearings of the series 511, 512, 513 and 514 are single sided, the models 522, 523 and 524 are double sided. Thrust ball bearings are composed of shaft washers, cage washers, and cage assemblies. The bearings are separable; cage assembly and bearing washers can therefore be fitted independently of each other. Both models tolerate high axial forces, however, they may not be radially stressed.

Single row deep groove ball bearings (Typ: 6000/6200/6300) Double row deep groove ball bearings (Typ: 4200) RDEEP GROOVE BALL BEARING Single row deep groove ball bearings (Type: 6000/6200/6300) Double row deep groove ball bearings (Type 4200) Deep groove ball bearings are wide ranging, non-separable bearings with solid outer rings, inner rings and bearing housings. These simply built products, steadfast in operation and maintenance friendly, are available as single and double row as well as sealed and open. In technical production, open bearings can have a recess on the outer ring for seals or cover rings. Due to their low moment of friction, deep groove ball bearings are suited to high speeds. Single and double row ball bearings are the most utilised anti-friction bearing. They are simple in construction, non-separable, suited to high speeds and unsusceptible in operation and maintenance. Narrow lubrication between running grooves and balls.

Self-aligning ball bearings are double row, non-separable components, composed of outer rings with concave raceways. In this way, their angle can be adjusted and they are resistant to angular misalignments or shaft deflections. The bearings are available as open and sealed units.

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.
