Precision Crossed Roller Bearing

RU-Integrated Inner/Outer Ring Type

THK ru series crossed roller bearings are high-precision, compact bearings designed for applications requiring exceptional rotational accuracy and load capacity. Unlike conventional bearings, RU series bearings integrate an inner and outer ring structure, eliminating the need for a separate housing or shaft. This design enhances rigidity while reducing installation space.

RB-Separable Outer Ring Type

The thk rb series standard type cross roller bearing is a high-precision bearing designed for applications requiring high rigidity and rotational accuracy. This series features a compact, integrated structure in which cylindrical rollers are arranged orthogonally in a single raceway, enabling it to support loads from all directions, including radial, axial, and moment loads.

RE-Two-piece Inner Ring Type

The thk re series crossed roller bearings are high-precision bearings designed to handle complex loads with superior performance. These bearings feature a compact, space-saving design while offering high rigidity and rotational accuracy. The rollers are arranged at right angles to each other in a cross pattern between the inner and outer rings, enabling them to support radial, axial, and moment loads simultaneously.

RA-Separable Outer Ring Type

Thk ra series slim type crossed roller bearings are designed to provide high rotational accuracy and rigidity while maintaining a compact and lightweight structure. These bearings feature crossed roller arrangements, where cylindrical rollers are positioned at right angles to each other in an alternating pattern between the inner and outer rings. This unique design enables the RA Series to withstand loads from all directions, including radial, axial, and moment loads, making them ideal for applications requiring high precision and space efficiency.

CRBH-High Rigidity Type

The IKO CRBH series high rigidity type crossed roller bearings are precision-engineered bearings designed to provide exceptional rigidity, high rotational accuracy, and compact structure. These bearings integrate an inner and outer ring with a one-piece construction, eliminating the need for a separate outer ring, which enhances rigidity and load capacity.

CRBS-Slim Type

IKO CRBS series thin crossed roller bearings are high-precision, high-rigidity bearings that utilize a special crossed roller structure design that allows the rollers to be vertically staggered at 90° between the inner and outer rings, thus being able to simultaneously withstand loads from all directions, including radial, axial and moment loads.

SX-Outer Ring Split Type

SX series crossed roller bearings are a type of rolling-element bearing specifically designed for applications demanding high precision, rigidity, and load-carrying capacity in a compact space. The defining characteristic is the crossed roller arrangement, where cylindrical rollers are arranged alternately at right angles to each other between inner and outer rings.

XSU 08-Sealed on Both Side

The high precision xsu 08 series crossed roller bearings are designed for applications that require high load capacity and precise rotational movement in a compact space. Featuring a unique design where cylindrical rollers are arranged at 90-degree angles, these bearings can accommodate axial, radial, and moment loads simultaneously.

XSU 14-Sealed on Both Side

The xsu 14 series crossed roller bearings are high-precision bearings designed for applications requiring superior rotational accuracy and rigidity. These bearings feature a compact structure with an integrated inner and outer ring, allowing for direct mounting without the need for additional housings.

XV-Inner Ring Split Type

The high precision XV series crossed roller bearings are designed for applications requiring exceptional accuracy, rigidity, and load-bearing capacity in a compact structure. These bearings feature an innovative crossed roller arrangement, where cylindrical rollers are positioned at right angles to each other between the inner and outer rings. This unique design enables them to support radial, axial, and moment loads simultaneously while maintaining minimal rotational resistance and high precision.

XR/JXR Double Outer Race-Two Inner Races

Crossed tapered roller bearings, such as the Timken XR, JXR, and PSL 912 series, are engineered to provide high rotational accuracy and rigidity while conserving space and material costs. These bearings feature two sets of races and rollers arranged at right angles, with alternating rollers facing opposite directions. This configuration allows them to withstand high overturning moments, making them ideal for applications like machine tool tables in vertical boring and grinding machines, as well as various pivot and pedestal applications.
