The use of high-precision radial groove ball bearings is especially recommended when axial forces are supported in two directions, but the installation space makes the use of a spindle bearing pair impossible; plus when the best-possible guide for rotating components is needed, but the RPM requirements are less important. Depending upon the load capability and the installation space available, GMN provides deep groove ball bearings in sizes 60 and 62 as per DIN 625. A large selection of various cages, lubricants and covers make it possible to adapt GMN deep groove ball bearings to any application.

The MBS standard cylinder series is characterized by a variable and stroke-independent welded construction. Due to the uniform force transitions between the different sizes and the different connection situations, they are often used in the areas of mobile and stationary hydraulics. Cylinder connection is via welded rod ends and bolted radial bearings. Connections with threaded holes for pipe fittings according to BSPP ISO 1179-2 are planned. With the exception of the piston rod, all surfaces are protected against corrosion with a black primer. On request alternative surface treatments are possible. The surface of the piston rod is hard chromed, ground and polished. The cylinders are suitable for hydraulic fluids of types H, HL and HLP according to DIN 51524/51525. If you have questions about areas of application or other options, we are happy to answer them. Download the data sheet for detailed information:

The highly torsionally flexible ACRUSAFLEX-VSK coupling is used in a drive train when a large shaft displacement or an extended distance between the drive and the driven components must be compensated. Depending on the arrangement of the drive train components, a non-uniform motion of the speed may result, and since cardan shafts exhibit some torsion flexibility, the mass of the prime mover and driven machine may induce a resonant system. Advantages of the highly tosrionally flexible ARCUSAFLEX-VSK couplings: Linear torsional deflection characteristic Elements available in different torsional stiffnesses Enhanced damping capacity through frictional damping Available in 9 sizes: from 390 Nm to 20.000 Nm Maintenance-free coupling bearings Radial bearing close to the cardan joint •A variety of designs for different cardan shaft configurations •Many types with SAE connection dimensions or as specified •Compact construction, the highly flexible element being protected by the...

The barrel coupling consists of a sleeve provided with semicircular toothing around its internal diameter and a hub that is externally toothed in a similar way. A series of cylindrical barrels, of hardened steel, are inserted in the holes formed by this toothing to act as power transmission elements. Covers with their corresponding special seals serve to assure the perfect tightness of the inner zone, preventing the penetration of dust and guaranteeing the continuity of the necessary lubrication. The most important characteristics and adcantages of barrel roll couplings: for alignment error compensation for ease of assembly especially wear-resistant with high durability minimises effect of alternative bending of the torque on the toothing designed for bearing large radial loads by distributing them over large barrel support surfaces Perfect tightness of the inner zone prevent the penetration of dust We are glad to see that you are interested in our product line and are happy to...

Are you operating an application requiring a bearing arrangement with high load carrying capacity with low-noise operation? Our durable four-point bearings are the perfect solution for this scenario and can support high axial loads as well as radial forces (relatively lower) in both directions. Four-point bearings are similar in structure to double-row angular contact ball bearings, but are much narrower in the axial direction due to a single raceway. The circular arc-shaped raceways in the inner and outer ring have opposite centres of curvature so that the balls contact the races at four points under radial load. If there is a predominantly radial load, four-point bearings should be avoided due to the higher friction in four-point contact. In assembly, one of the two races, often the inner race, is split to insert the balls. Since four-point contact bearings are often installed radially exposed, the outer rings can optionally be equipped with retaining grooves to prevent rotation.

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.

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.

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.

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.
