ハイウィン List of Products and Services

This document introduces the features and types of "Cross Roller Bearings" handled by HIWIN Corporation. Patent-acquired design for high load capacity. It mainly consists of an outer ring, inner ring, multiple rollers, and several spacers. When there is a load on the bearing, the area that bears the load increases, reducing the elastic deformation amount and enhancing the durability of the bearing.

The Hiwin cross roller bearing, characterized by high rigidity and high rotational accuracy, is compact and easy to install. Both the sealed and open types have oil holes, allowing for grease filling. The rollers are separated by retainers, which reduce friction and rotational torque between the rollers. It is suitable for a wide range of applications as a rotating component in industrial automatic control devices, machine tools, inspection equipment, and medical devices. It consists of an integral inner ring and an outer ring fixed with screws to prevent separation of the two-part ring. ■ Sealed type (WW): Seals on both sides prevent foreign matter from entering the raceway and grease leakage. ■ Open type (NN): No seals on either side. It has low friction resistance and is used for low-torque bearings. In both cases, grease can be replenished through the oil holes. They can be used in a wide range of applications as rotating components in industrial automatic control devices, machine tools, inspection equipment, and medical devices.

The lineup is smaller than CRBA, but the main dimensions are the same. Hiwin's cross roller bearings, characterized by high rigidity and high rotational accuracy, are compact and easy to install.

They are suitable for a wide range of applications as rotating components in industrial automatic control devices, machine tools, inspection equipment, and medical devices. They consist of an inner ring fixed with screws to prevent separation of the two-part ring and an outer ring with a one-piece structure. ■ Sealed type (WW): Seals on both sides. Prevents foreign matter from entering the raceway and grease leakage. ■ Open type (NN): No seals on either side. Used for low-torque bearings due to low friction resistance. In both cases, grease can be replenished through the oil holes. They can be used in a wide range of applications as rotating components in industrial automatic control devices, machine tools, inspection equipment, and medical devices.

Hiwin's cross roller bearings, characterized by high rigidity and high rotational accuracy, are compact and easy to install. The bearing structure is arranged in a more innovative way. Surface treatments are also available to accommodate use in special environments. ■ Sealed type (WW): Seals on both sides. Prevents foreign matter from entering the raceway and grease leakage. ■ Open type (NN): No seals on either side. Used for low-torque bearings due to low friction resistance. Both types allow for grease replenishment through oil holes. They can be used in a wide range of applications as rotating components in industrial automatic control devices, machine tools, inspection equipment, medical devices, and more.

While being 40% more compact than conventional products, it achieves high rigidity and high load capacity by integrating the inner and outer rings. It contributes to the lightweight and space-saving of the device.

Hiwin's cross roller bearings, characterized by high rigidity and high rotational accuracy, not only offer a comprehensive lineup but also accommodate custom products. Both sealed and open types have oil holes, allowing for grease filling. The rollers are separated by separators, reducing friction between the rollers. They can be used in a wide range of applications as rotating components in industrial automatic control devices, machine tools, inspection equipment, and medical devices. ■ Sealed type (symbol WW): Uses oil seals to prevent foreign matter from entering the raceway and to prevent grease leakage. ■ Open type (symbol NN): Features a non-oil seal structure, resulting in low friction resistance, suitable for low-torque bearings.
