Deep Groove Ball Bearings
Deep groove ball bearings are versatile, self-retaining bearings. These bearings, which are of simple design, robust in operation and easy to maintain, are available in single row and double row designs and in open and sealed variants.

Angular Contact Ball Bearing
In angular contact ball bearings, the forces are transmitted from one raceway to the other at a specific contact angle (oblique to the radial plane). The bearings are therefore suitable for radial and axial loads acting simultaneously.
As the nominal contact angle increases, so does the axial load carrying capacity. As a result, angular contact ball bearings are more suitable than deep groove ball bearings for supporting higher axial forces.
The bearings are available in a single row design as single bearings or as a pair of universal bearings as well as in a double row design.

Four Point Contact Ball Bearings
Due to the large contact angle on both sides, the bearings can support alternating, pure axial or predominantly axial loads.
Four point contact bearings are similar in their structure to double row angular contact ball bearings, but are considerably narrower in an axial direction due to only one raceway groove. Since the centres of curvature of the arc-shaped raceways on the inner ring and outer ring are offset relative to each other, the balls are in contact with the bearing rings at four points under radial load. For this reason, four point contact bearings are only used under predominantly axial load.

Self-aligning Ball Bearing
In the self-aligning ball bearing, two rows of rolling elements are supported in two raceway grooves in the inner ring. The raceway on the outer ring has a curved form. The cage combines the two rows of balls and the inner ring to form a unit that can align itself by swivelling relative to the outer ring.

Axial Deep Groove Ball Bearings
Axial deep groove ball bearings are single direction or double direction ready-to-fit units that can support high axial forces and are not self-retaining. Owing to their construction, the bearing parts (shaft locating washer, housing locating washer, ball and cage assembly, support washer) can be mounted separately from each other.

Insert Ball Bearing
Radial insert ball bearings are ready-to-fit machine elements. In combination with drawn shafts, they are particularly easy to fit and suitable for the design of economical bearing arrangements. They are highly suitable where predominantly radial loads must be supported.

Cylindrical Roller Bearings
Cylindrical roller bearings have a single or multiple row rolling element set based on cylindrical rollers. In contrast to the ball, the roller has a larger contact area perpendicular to the roller axis. As a result, it can transmit higher forces, has greater rigidity and allows smaller rolling element diameters under the same load.

Tapered Roller Bearings
Tapered roller bearings comprise an outer and inner ring with tapered raceways as well as tapered rollers in a window cage. These are single row individual bearings, usually of open design, which for technical reasons are always adjusted against a second tapered roller bearing in a mirror image arrangement. Open bearings are not self-retaining. As a result, the inner ring with the rollers and the cage can be mounted separately from the outer ring.

Axial Tapered Roller Bearing
Axial tapered roller bearings can support very high axial forces and have high rigidity.
Spherical Roller Bearings
The outstanding feature of all spherical roller bearings is angular adjustability. This is achieved with a double row rolling element set based on symmetrical barrel rollers, which orient themselves freely on the mutually curved raceway in the outer ring and the two raceways inclined relative to the bearing axis in the inner ring.

Axial Spherical Roller Bearings
Axial spherical roller bearings are single row units comprising a shaft locating washer, housing locating washer and asymmetrical barrel rollers with cages. The cage holds the roller and cage assembly and the shaft locating washer together. The bearings can be dismantled. As a result, the bearing components can be fitted separately.
Linear Guidance Systems
Linear Ball Bearings
Linear bearings are designed to reduce friction in various piston assemblies and linear displacement mechanisms. They are used in robotics, woodworking, the tool industry and many other branches of mechanical engineering. Structurally, linear bearings can be designed for unlimited or limited reciprocating motion. Their rolling elements can be balls and rollers (needle-shaped or cylindrical). Linear bearings can be supplied with or without protective seals.
Linear Roller Bearings
For linear bearings, needle rollers were first incorporated into non-recirculating linear guides, but manufacturers have recently introduced recirculating profiled rail guides with needle roller bearings to meet ever-increasing demands for rigidity and smoothness of motion.

Axial Angular Contact Roller Bearing
Angular contact roller bearings AXS comprise thin, formed bearing rings, between which injection-moulded plastic cages with cylindrical rollers are arranged. In contrast to comparable axial rolling bearings, series AXS has a particularly small cross-section, whilst the load carrying capacity and tilting rigidity are very high in relation to the loaded installation space. The ready-to-fit machine elements are not self-retaining and are therefore very easy to assemble as the individual parts can be installed separately.

Needle Roller Axial Cylindrical Roller Bearing
Needle roller/axial cylindrical roller bearings can support axial forces in one direction as well as high radial forces.
These bearings comprise a radial needle roller bearing and an axial cylindrical roller bearing with a plastic cage. They do not have an inner ring and require a shaft raceway that is hardened and ground. If the shaft cannot be used as a rolling bearing raceway, inner rings IR can be used instead.

Needle Roller Angular Contact Ball Bearing
In addition to radial forces, needle roller/angular contact ball bearings can support axial forces in one or both directions. Needle roller/angular contact ball bearings capable of supporting axial loads in one direction act as semi-locating bearings, while bearings capable of supporting axial loads in both directions act as semi-locating or locating bearings.

Needle roller/angular contact ball bearings capable of supporting axial loads in one direction act as semi-locating bearings, while bearings capable of supporting axial loads in both directions act as semi-locating or locating bearings.
Crossed Roller Bearing
Crossed roller bearings can support high loads. Due to the X arrangement of the cylindrical rollers, they can support axial forces in both directions, radial loads, tilting moment loads and any combination of loads by means of a single bearing position. As a result, it is generally possible to reduce conventional bearing arrangements comprising two bearing positions (bearing arrangement with one radial and one axial bearing) to one bearing position.

As a result, it is generally possible to reduce conventional bearing arrangements comprising two bearing positions (bearing arrangement with one radial and one axial bearing) to one bearing position.
Slewing Rings
Slewing rings are generally large size ball or roller bearings with very high load carrying capacity for oscillating motions and slow rotary motions.
The bearings are mainly mounted in a horizontal position and are used to support axial forces and large tilting moments. Radial loads only occur to a subordinate extent. The bearing rings are generally screw mounted directly to the immediate parts of the adjacent construction.
The inner or outer ring can be provided with teeth to facilitate drive solutions.
