Features of cross roller bearings

HGT crossed roller bearing (cross roller bearing) comes in RA, RB, RE, RU, SX, and CRBH six series; each has its feature. We provide a free cross roller bearing design based on your requirements. Especially for the face mount crossed roller bearing; solid tech support is the key to selecting perfect products for your application. After installing the rollers and cage, the detachable inner ring (or outer ring) will be fixed with the shaft washer. To prevent the separation, installing the shaft washer should be simple. The cage enables the friction between rollers to disappear. And also prevents rollers from falling on one side, obtaining a stable torque. The rollers are orthogonally arranged, so only one set of the Crossed Roller Bearings can withstand the loads. Compared with the traditional series bearing, the current cross series bearings have increased rigidity three to four times.

Six Types of HGT crossed roller bearing

HGT RA series

The HRA series can reduce the thickness of the inner and outer ring to the lowest level. The HRA series bearing is suitable for applying lightweight, compact style, and high-precision rotation of the inner ring. As the rotating part in a mechanical watch.

RB series

The HRB series, the primary series bearing of the Crossed Roller Bearing, has the separable outer ring, and its inner ring is integrated with the main body. This series bearing is used in the part where the high-precision rotation in the inner ring is required.

RE series

The HRE series is also a primary series of the Crossed Roller Bearing. It has the same outer dimension, but the HRE series is inner ring separable and outer rings rotating. It can be used in the position where the high-precision rotation of the outer ring is required.

RU series

With mounting holes on both the outer and inner rings, the HRU series crossed roller bearing, the HXU series crossed roller bearing, and the HXSU series crossed roller bearing do not need the presser flange and the housing. In addition, they are equipped with washers; their performance is minimally affected by the mounting procedure. This kind of design can help obtain stable rotation accuracy and torque. This series bearing can be used in both outer and inner rings rotated devices.

SX series

Like the HRB series bearing, the HSX series crossed roller bearing is also slim; however, it has smaller sectional dimensions. Its outer ring is detachable, while the inner ring is integrated with the main body through three fixed rings. Since the inner and outer rings do not have mounting holes, it requires a presser flange and housing for installation. This series bearing can be used in the areas where the inner ring requires high-precision rotation

CRBH series

The HCRBH series is a slim HRU series. Without the mounting holes on both inner and outer rings, it requires a presser flange and housing for the installation. The design of HCRBH has little impact on its performance, achieving stable rotation accuracy and torque. This series bearing can be used in the device requires both the outer and inner ring rotation. And also, the bearing dimensions are more diminutive compared to other series of cross roller bearings.

Crossed-roller bearings are bearings for high-precision applications. They comprise outer rings, inner rings, rolling elements, and spacers. The outer ring is split and is held together by retaining rings.

Due to the cross arrangement of the cylindrical rollers, these bearings can support axial forces from both directions and radial forces, tilting moment loads, and any combination of loads using a single bearing position. As a result, designs involving two bearing positions can be reduced to a single bearing position. Crossed roller bearings are very rigid, have high running accuracy, and supply normal, low, or preload. The outer bearing rings are easily fixed to the adjacent construction using clamping rings.
