HGT Crossed Cylindrical Roller Bearing is one kind of bearing whose rollers are square crossing arranged between outer ring and inner ring. The rollers contact with the raceway in linearity, so this bearing has better rigidity and less elastic strain. At the same time, this bearing can carry radial load, axial load and moment load simultaneously. They are especially suitable for high rigidity and high running accuracy applications.
The dimension of the inner and outer rings is a minimum to miniaturization, especially for the extremely-thin type that is close to the limit of small size with high rigidity, so it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical instrument, measuring instruments, IC manufacturing machines, and etc.
HSX crossed roller bearing series(outer ring division type with inner rotating, thin section),this type has smaller section than HRB series. Due to the extremely thin structure, there is no mounting holes on the outer ring and the inner ring, so the model requires a presser flange or housing. Crossed roller bearings are very rigid, have high running accuracy and are supplied with normal clearance, low clearance or preload. Preloaded bearings have the suffix VSP. The bearing outer rings are easily fixed to the adjacent construction using clamping rings.
HRA series is a kind of small size and light weight cross roller bearing which the wall thickness is thinner. it is small and can with stand heavy load. So bearing housing and presser flange can be light wight. It can be suited for the hand location of the robots used in the rotary location.
HRB crossed roller bearing series (outer ring division type with inner rotating), this type is the basic type of crossed roller bearings. The outer rings have two parts, and the inner ring is one integer. The type is well applied to the situation which need high rotation accuracy on inner ring. For example, it is suitable for the rotary part of the indexing table of the tools machine.
HRE crossed roller bearing series (inner ring division type with outer rotating), which is also the basic type of crossed roller bearings. The size is the same with that of RB series. The inner rings have two parts, and the outer ring is one integer. The type is well apply to the situation which need high rotation accuracy on outer ring.
