HGT Crossed Cylindrical Roller Bearings Applied Features

2019/08/16 09:54 USHGT

Applied Features
After installing the rollers and clearance cage, the separable inner ring (or outer ring) will be fixed with the shaft washer. In order to prevent the separation, the installation of the shaft washer should be simple. The clearance cage enables the friction between rollers to be disappeared and prevent rollers from falling down on one side, which is able to obtain a stable torque. The rollers are orthogonal arranged, so only one set of the Crossed Roller Bearings can withstand the loads from different directions. Compared with the traditional series bearing, the current series bearings have increased the level of rigidity by three to four times.

Types
The HRA series crossed roller bearing is compact that reduces the thickness of the inner and outer ring to the lowest level. With the division in the outer ring like the HRB series bearing, the HRA series bearing is suitable for position where the light weight, the compact style and he high-precision rotation in the inner ring are needed, such as the rotating part in mechanical watch.


The HRB series crossed roller bearing, the basic 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.


Like the HRB series  bearing, the HRE series crossed roller bearing is also the basic series bearing of the Crossed Roller Bearing. It has the same outer dimension with the HRB series bearing, but the difference is the structure that the HRE series bearing halves the inner ring and integrates the outer ring. It is can be used in the position where the high-precision rotation in the outer ring is required.


With mounting holes on both outer ring and inner ring, 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, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure, which can help obtain the stable rotation accuracy and torque. This series bearing can be used in the rotation areas of both outer ring and inner ring.


Like the HRB series bearing, the HSX series crossed roller bearing is also slim; however, it has smaller sectional dimensions. Its outer ring is separable while the inner ring is integrated with the main body through three fixed rings. Since the inner ring and outer ring do not have the mounting holes, its 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


The HCRBH series crossed roller bearing is a slim type of the HRU series bearing. Without the mounting holes on both inner ring and outer ring, its requires a presser flange and housing for the installation. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, the installation has little impact on its performance, which can achieve the stable rotation accuracy and torque. This series bearing can be used in the rotation areas of both outer ring and inner ring while dimensions of the bearing are smaller.
