Rolling bearings/plain bearings
for industrial applications

Function:

Angular contact ball bearings are self-retaining units with massive external and inner rings and ball-cage assemblies with polyamide, metal sheet or brass cages. The bearings are suitable for high rotational speeds. According to the design, steel or ceramic balls are used. Grease or oil lubrication is used for lubrication. The raceways of the inner and outer rings are staggered in the direction of the bearing axis. Angular contact ball bearings are especially suitable for storage systems that have to support combined loads, i.e. simultaneously acting radial and axial loads.

Application:

Due to its enormous axial and radial resilience and high rigidity, the bearings are also often used in spindle construction, for example.

Function:

Two-sided axial angular contact ball bearings are not self-retaining precision bearings. These bearings are made of solid shaft washers, housing washers, a spacer ring as well as angular contact ball and cage assemblies with stable solid brass cages. They meet the requirements for high precisions of the narrowed tolerance class P. Each component of these bearings is precisely matched to one another and allows separate mounting. But it is important that they are not roughly interchanged with other bearings to ensure correct functionality.

Application:

They are used for the storage of rotary plates in drilling rig turntables, but can also be used for other storage applications.

Axial deep groove ball bearings are specially designed for housing high axial loads, but they should not be subjected to radial loads. Their construction consists of ball-cage assemblies, shaft washers and housing washers. In contrast to self-retaining bearings, they are no self-centering. This special feature enables the ball-cage assembly and bearing washers to be mounted separately, which in turn allows independent configuration and positioning.

Application:

Automotive industry, industrial machinery like heavy-duty machines, machine tools and conveyor systems, energy industry, transportation industry

Deep groove ball bearings are extremely versatile rolling bearings that can meet a wide pallet of requirements. They are able to handle not only radial loads, but also axial loads in both directions at the same time. These bearings are available in various configurations, as single-row or two-row designs, as well as in open or sealed form. Deep groove ball bearings are characterized by their self-retaining properties, consisting of stable outer rings, inner rings and ball-cage assemblies that guarantee reliable power.

Application:

Due to their robustness, smooth running and low-noise rotation, they are usable almost everywhere. Depending on the operating conditions, deep groove ball bearings are also made of stainless steel, ceramic or plastic.

Miniature bearings are a special form of ball bearings that were developed for applications with limited installation space due to their small dimensions. These bearings have smaller dimensions than conventional ball bearings and are designed for precise and light applications. Despite their small size, miniature bearings offer efficient power by being able to support both radial and axial loads while ensuring low-friction rotation.

Application:

Miniature bearings are especially suitable for installation in small electric motors, medical devices, mechatronics and household appliances due to their small construction size and inserts at high rotational speeds.

Function:

Self-aligning ball bearings are two-row, self-retaining units. They consist of an inner ring with a cylindrical or tapered hole, outer rings with a hollow ball raceway and ball-cage assemblies. The bearings are available open and sealed. Self aligning ball bearings were developed, for example, to to increase the operational reliability of long transmission shafts, for example. Self aligning ball bearings are angularly movable and insensitive towards misalignment of the shaft to the housing. These bearings are especially suitable for bearings where big shaft bends or misalignments are to be expected.

Application:

Self aligning ball bearings are inserted when the shaft and housing are not optimally aligned with each other. The bearings are angularly movable and insensitive towards misalignment of the shaft to the housing.

Function:

The CARB toroidal roller bearing combines the angular mobility of a spherical roller bearing with the constraint-free axial moveability of a cylinder or needle roller bearing. The CARB bearing was specially developed as a non-locating bearing for angularly movable bearings. The CARB bearing absorbs misalignments and axial displacements of the shaft with virtually no friction, without causing additional axial loads. The outer ring can be installed with a fixed fit because the axial displacement takes place in the bearing and not between the outer ring and housing. There is no need for the user to compromise between interference fit and axial freedom. The fixed fit prevents the creep and fretting corrosion phenomena known at conventional bearing arrangements. The user benefits from low operating temperatures and vibration levels, a longer bearing and lubricant service life, higher operational reliability and lower energy consumption.

Application:

Paper machines, continuous casting systems, ventilators, fans, crushers, tube mills, industrial gearboxes, conveyor systems, textile machines, swivel technology, hydraulic motors, pumps, vehicles, pinion shafts and main drive shafts of wind turbines.
