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.

Our housings and their respective bearings form bearing units which have proven themselves in machines, plant and other equipment. Bearing housings are usually made of cast iron, on request we can deliver housings in cast steel and nodular graphite cast iron. As the bearings are usually lubricated with grease, and this first lubrication holds for quite a while, most housings don’t have re-lubrication holes. There are however, gates or markings present, so that lubrication holes can be fitted if necessary. When re-lubricating, it must be ensured that excess lubricant can escape. The bearing seating points in the housings are usually machined so that the bearings are movable, so they function as floating bearings. Fixed bearings are achieved by inserting fixing rings, if these are listed in the table. Fixing rings must be ordered separately. Housings without fixing rings are delivered as floating bearing models (L) or fixed bearing models (F).

In an industrial facility,motors and turbines use energy to produce rotational mechanical motion.In order to realize this motion, are needed power transmission products to transmit it to other components and machines. Chain drives consist of an endless series of chain links,which mesh with toothed sprockets. Are used to perform three basic functions:transmitting power,conveying materials and timing purposes. Chain drives transfer speed and torque through the use of a linked chain and sprockets. KFB Clarfeld offer chains and sprockets produced according to ISO or ANSI norms.

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.

Single row cylinder roller bearings with retainer are available as loose bearings, support bearings and fixed bearings. In the range of single row cylinder roller bearings are the model types N, NJ, NU and NUP, whereas the model series NN includes the double row cylinder roller bearings.

Tapered roller bearings are composed of solid outer and inner rings with tapered raceways and tapered rollers with cage assembly. The bearings are separable. Therefore, the inner ring with the rollers and the assembly cage can fitted separated from the outer ring. Tapered roller bearings tolerate high radial and one sided axial forces. For axial steadying, a second bearing is usually necessary, which is then fitted mirror-inverted.

Axial needle cage assemblies Axial needle cage assemblies, composed of synthetic or metal axial cage assemblies with integrated needle rollers, have an extremely low overall height. They tolerate high axial forces acting in one direction, radial forces must be taken up separately. The deployment of axial needle cage assemblies requires that hardened and bevelled thrust surfaces may be used as raceways. Thrust bearing washers Thrust bearing washers are punched, hardened and polished and can be used as shaft or housing washers. These washers are appropriate when the adjoining machine part when not hardened, is rigid enough and of a stable form. Axial needle bearings Axial needle bearings are components made up of axial needle rollers and cage assemblies and axial washers with centring bore. They can be combined with needle sleeves, needle bushes and needle bearings. The thrust surface for the cage assembly must be hardened and bevelled. The product types AXK and K are applicable here

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.
