Thrust bearing / Spherical axial bearings from igus d1 [mm]: Mechanical properties The self-aligning spherical igubal ® thrust bearings are very easy-to-mount units, which help to compensate for errors and prevent misalignments. The thrust bearing housing pad is made of the impact-resistant, stiff, thermoplastic composite material igumid G. The standard thrust bearing washer is made of iglidur® W300. This combination provides particularly good gliding and wear properties in relative movements. Loads The load carrying capacity of the spherical igubal® thrust bearing is very high in normal ambient temperature. In particular cases the load carrying capacity of the axial bearings should be checked in a practical trial with high constant loads and at higher temperatures. Coefficients of surface friction and speeds Taking the radial loads into account, maximum surface speeds up to 0.5 m/s rotating can be attained. Installation The axial bearing pad is mounted flush and secured. The spherical washer glides loosely in the pad and is held by the shouldered shaft mounted on it. Delivery program As standard, the spherical igubal® axial bearings are supplied in sizes of 5 to 20 mm. For other dimensions, please contact us.

Material Schulz Stanztechnik manufacturers these axial ball bearings using the materials suited to the specific application. For the housing, steel, brass or stainless steel are used; for rings, steel or stainless steel which is always hardened. The balls are made of chrome or stainless steel, which is also always hardened. All material combinations – depending on their conditions of use – are possible for the assembly of the individual parts. Various surface coats for the individual parts can be supplied as well as finished bearings: brass which is uncoated or nickel plated; steel and stainless steel which is uncoated, zinc plated or nickel plated. All bearings are available lubricated or unlubricated. Structure DLG100 axial ball bearings consist of sheet metal housing, two hardened rings as well as hardened precision balls. Due to their structure, we refer to them as an encapsulated, full ball design.

Housing washer, shaft washer and rolling elements, bearing steel. Cage, steel. Note Axial ball bearings accept high axial loads from one direction but may not be loaded radially. The bearings are separable. This means the bearing parts can be fitted independently of each other. The main dimensions of the axial ball bearing conform to ISO 104 and DIN 711. Dimensional and running tolerances correspond to tolerance class PN acc. to DIN 620. These tolerance classes are standard and are well suited for most applications.

Steel housing. Nitrile rubber seal. Preloaded highaccuracy bearings with a 60° thrust angle. The bearings accept both radial and axial forces from both directions. Due to their preload, the angular contact ball bearings provide a high level of stiffness, excellent concentricity, precise tool positioning and repeatability. The integrated lowfriction seal effectively keeps dirt away from the bearing, thereby ensuring excellent operating safety and a long service life. The bearing friction coefficient Mrl is a reference value. The moment of inertia corresponds to that of the rotating inner ring. The limiting speeds are applicable after grease is applied. Technical data All bearings are supplied ready for mounting with lubricating grease type KE2P35 acc. to DIN 51825. Housing and shaft tolerances correspond to roundness tolerance class IT2 and perpendicularity tolerance class IT4.

Selflubricating. Hardness 190220 HB. Note The guide bushes are radially and axially applicable. The bearing elements are maintenancefree and wearresistant. The graphite inserts provide lifelong lubrication. Preferably for travel speeds < 0.5 m/s. (Additional lubrication is recommended for extreme loading with a higher travel speeds). Temperature range Temporary temperature peaks up to ca. 200°C. Tolerances The bore for the bearings should correspond to ISO tolerance H7. The tolerance h6 to h7 is recommended for the shaft.

The axis height of the spindle bearings matches the fixed bearing unit 2407801. The floating bearing units consist of a housing with deep groove ball bearing, which adapts axially to the linear expansion of the spindle.

Like all Hense rotary vane motors, rotary vane motors in the HSS series are designed according to the rotary vane principle. The drive shaft has axial and radial plain bearings in coated bushes. The coating used is tribologically optimized and ensures low wear. Sufficient lubrication of the bearing points is ensured by the supplied hydraulic oil. To reduce the internal friction of the motor, the hydraulic separation of the working chambers in this series is partly achieved by means of pressure and viscosity-dependent throttle sections. HSS motors are ideal for generating oscillating swivel movements in the frequency range with small angular amplitudes in controlled systems. The HSS series is therefore recommended for use whenever semi-dynamic torsion tests need to be carried out reliably and cost-effectively.

KIS deep groove ball bearings are characterised by their high load carrying capacity and speed stability. Depending on the requirements of your application, they are available in different variants and in both radial and axial design. Our single row deep groove ball bearings are available in open and sealed designs. Open bearings are maintenance-free, while sealed bearings offer better corrosion protection. Single row deep groove ball bearings can support both radial and axial forces. Our double row deep groove ball bearings feature a higher radial load carrying capacity. They are used when the radial load carrying capacity of single row deep groove ball bearings is not sufficient. Axial deep groove ball bearings are suitable for supporting particularly high axial loads. They are available in both single and double direction. Single direction thrust ball bearings can only support axial forces, while double direction thrust ball bearings can support both radial and axial forces.

KIS needle roller bearings are ideal for applications that require space-saving rolling bearings with high load carrying capacity. We offer needle roller bearings in both radial and axial designs as well as in combined designs. In bearing technology, cylindrical rolling elements are referred to as needles if the rolling element diameter is ≦ 6 mm and the ratio of rolling element diameter to rolling element length gives a value Dw/lw ＜ 1:3. Radial needle roller bearings are intended exclusively for use as non-locating bearings. The given axial displacement path for bearings with an inner ring allows axial movements between the shaft and the housing. If necessary, wider inner rings are available to allow larger axial displacement paths. Our combined needle bearings are characterised by particularly high precision and efficiency. By integrating both bearings into one unit, combined needle roller bearings are often easier to press in and easier to handle than individual solutions.

We manufacture our KIS tapered roller bearings in both single and double row designs. Since they can support both axial and radial forces, they can also withstand high loads. Due to their high precision they are suitable for shafts that are to be guided axially precisely (locating bearings) or if the bearing Tapered roller bearings are easy to adjust and disassemble, making them easy to mount and maintain. Tapered roller bearings are the perfect choice for applications where high loads or high precision are required. Our KIS tapered roller bearings are used in a wide range of applications, such as motors, compressors, construction machinery, machine tools and gearboxes. We will be happy to advise you on possible variants with different properties.

The output shaft of the HSH swivel motors has radial and axial hydrostatic bearings. Here, radially and axially arranged bearing pockets are supplied with pressurized oil via a separate pressure connection. As a result, the output shaft is centered radially and axially between liquid cushions and all metallic contact surfaces are permanently separated from each other by a thin liquid film. This eliminates wear caused by metallic friction in any operating state, even at zero speed compared to hydrodynamic plain bearings. In conjunction with highly dynamic control valves and angle of rotation sensors, these actuators are preferably used in controlled systems in which disturbance variables such as friction and the stick-slip effect must be reduced to a minimum. Furthermore, due to the lack of internal seals, they are ideal for test series with large numbers of load cycles where an interruption, e.g. due to the replacement of internal seals, is not permitted.
