Crossed roller bearing - Import export

Designed to efficiently support axial and radial forces and tilting moment loads, crossed roller bearings are suitable for applications subject to high loads and speeds. Due to the special crosswise arrangement of the cylindrical rollers in crossed roller bearings, designs with two bearing positions can often be reduced to one. Due to their high rigidity and running accuracy, they offer enormous precision and are used, for example, in robotics, medical technology and lathes. Depending on the application requirements, we at KIS manufacture cross rollers in different configurations. We are happy to advise you on the optimum solution for your application.

The AntiCreep Cage Crossed Roller Way prevents cage creep by using a rack and pinion mechanism in the crossed roller way while also providing smooth linear motion with super high accuracy. The builtin rack and pinion mechanism is the perfect solution for cage creep. It provides reliable operation in various situations where a crossed roller way may have issues, including applications on a vertical axis. No correction for cage creep is necessary, even under high velocity or long term operation. Interchangeable Mounting Dimensions Since the rack is placed inside the way, it maintains the same outside dimensions. This provides complete mounting compatibility with the conventional crossed roller way, making it easy to replace the conventional type in machines and equipment, as well as using it in new designs.

The IKO Crossed Roller Way is a linear motion rolling guide that incorporates a roller cage between two linear ways with Vshaped surfaces that act as track grooves. Because the cylindrical rollers are alternately crossed, this arrangement can handle loads in any direction while providing extremely highaccuracy and smooth linear motion. Models are available in various sizes which can be selected based on the application.

Slim Type Crossed Roller Bearings are slim bearings having a small outside diameter against the bore diameter and a narrow width. In addition, types with cage, types with separator, and full complement types are available, which can be selected according to the intended use. Crossed Roller Bearings are compact bearings with their rollers alternately crossed at right angles to each other between inner and outer rings. The orthogonal array of rollers allows the bearing to handle complex loads simultaneously from any direction, which makes assembly possible without needing to worry about load direction.

The outer ring of the Standard Type Crossed Roller Bearings is made of two split pieces, which are bolted together to prevent separation during transportation or mounting, enabling easy handling. These bearings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc., which require compactness, high rigidity and high rotational accuracy. In addition, bearings made of stainless steel and those with inner and outer rings provided with mounting holes are also available on request. Please contact IKO.

High Rigidity Type Crossed Roller Bearing V has a solid onepiece construction for both inner and outer rings. Therefore, high accuracy and high rigidity are achieved, and mounting errors can be minimized. As separators are incorporated between the cylindrical rollers for smooth rotation, these bearings are suitable for applications where rotation speed is comparatively high. These bearings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc., which require compactness, high rigidity and high rotational accuracy. In addition, bearings made of stainless steel and those with inner and outer rings provided with mounting holes are also available on request. Please contact IKO.

The mounting holes in both inner and outer rings facilitate installation to your equipment. An open type and a sealed type are available. The sealed type incorporates special synthetic rubber sealing.

Using IKO CLube Linear Way L for the linear motion rolling guide and IKO Crossed Roller Bearings in the rotation guiding parts, while adopting direct drive method in the drive section, IKO Alignment Stage SA···DE is a compact, lowprofile alignment stage which achieves XYθ motion.Alignment Stage SA···DE achieves highly accurate positioning without backlash by combining a highresolution linear scale and full closed loop control. An ideal positioning mechanism for alignment processing using image processing, such as in semiconductor/liquid crystal manufacturing equipment, or for measuring instruments or testing and inspection equipment requiring clean environments.

The IKO Alignment Module AM is a positioning module developed for alignment stages by combining high rigidity Crossed Roller Bearings and Linear Way E with Precision Positioning Table TU. Alignment stages can be configured without adjusting the height of each alignment module, since the height tolerance is managed with high accuracy of ±10 μm.

Alignment Table AT is a rotary positioning mechanism capable of precise angle correction, in which a high rigidity steel table and bed are used and IKO Crossed Roller Bearings are incorporated in the bearings supporting the table. Alignment Table AT uses the ball screw drive to convert linear motion into circular motion in a fixed angle range and positions the table in the rotational direction. An IKO Linear Way L is used for the linear motion rolling guide of the ball screw drive mechanism, combined with a precision ball screw to achieve high precision positioning. Placing Alignment Table AT on the slide table of the IKO Precision Positioning Table enables the configuration of a low height XYθ multiaxis positioning mechanism. This enables the table to be used as an alignment table for precision measuring equipment, inspection equipment and assemblers.

These bearings are doublerow, full complement with a low cross sectional height designed for use in sheaves. There are two types, sealed and shield type. They can withstand heavy radial loads and shock loads at comparatively lowspeed rotations, and can also withstand axial loads. It is easy to fix them axially to sheaves using the stop rings of the outer ring. The width of the inner ring is designed to be larger than that of the outer ring, so they require no spacer between sheaves. The structure is stable because the doublerow of rollers can withstand the moment loads caused by rope transition. The surfaces of these bearings are also treated to provide high corrosion resistance.

IKO Roller Bearings are heavy duty bearings with rollers incorporated in a double row. They are nonseparable bearings with a high load rating. They can withstand not only radial loads but axial loads as well, which are supported at the contacts between the shoulders of the inner and outer rings and the end faces of the rollers. They should be used at the fixing side of a shaft. Like needle roller bearings, they are also compact. Roller bearing types include caged, full complement and the type for sheaves, and they can be selected based on the operating conditions. These bearings are used in heavyduty machinery such as construction equipment, and industrial machines.

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.

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.

With decades of experience, we manufacture spherical roller bearings at KIS that can support large radial and axial forces in both directions. The perfect solution for applications that have to withstand massive loads. Due to the design of two rows of pendulum-shaped rollers in a common, hollow-ball raceway in the outer ring, our spherical roller bearings can support large radial and also axial forces. This makes them perfect for applications that have to withstand high loads and shocks and compensate for shaft bending or misalignment. In addition to conventional spherical roller bearings (which have no seal and have either a tapered or cylindrical bore), there are also application-specific variants developed for special requirements (e.g. sealed spherical roller bearings or bearings with optimised load ratings). Spherical roller bearings offer high performance and efficiency and are available in a wide range of sizes and designs.

We offer our KIS cylindrical roller bearings in various designs and sizes. In addition to the number of roller rows and the design of the cage, the flanges on the inner and outer rings are also considered. Due to their low friction and high rigidity, our cylindrical roller bearings are the perfect, durable solution for applications with high radial loads. They can also compensate for axial displacements (e.g. due to thermal expansion) and are available in sealed designs. Sealed cylindrical roller bearings are protected from dirt, water and dust. The seal prevents the ingress of contaminants and keeps the lubricant in the bearing. Together with you, we will be happy to develop a customised KIS solution for your requirements.
