Product Description

 Detailed parameters-RU178 Cross Roller Bearings

Staff Style

Drawing-RU178 RU178G RU178X
RU178 is a precision cross roller bearings with cylindrical rollers as rolling elements. There are three types of mounting structures:
RU178; both inner and outer rings are smooth holes, and the countersunk holes are in the same direction;
RU178G; both inner and outer rings are smooth holes, and the countersunk holes are in opposite directions;
RU178X, the outer ring is smooth and the inner ring is threaded;

RU178GUUCCO is used for bearings with industrial mechanical arms,High Precision Bearing.
 
What kind of bearing is model RU178 bearing?
The cross roller bearings is suitable for precise applications requiring multi-directional bearing, such as robot arm, precision turntable, etc.
The bearing itself is designed with negative clearance, so the bearing is rigid enough to withstand large loads and has high precision (basically, it beats between 0.001mm and 0.01mm, and the bearing precision is above P5).
How to install this series of bearings?
The selection of cross roller bearing is mainly to consider the mounting mode and size of the bearing, which can be divided into the following two types:
1. The cross roller bearings without installation hole has a thinner wall thickness, which is suitable for small installation space. High Precision Bearing needs to be pressed on the equipment with flange plate. The specific difference of RB/RE/CRBH/SX/RA type is as follows
2. The inner and outer rings of the cross roller bearing with mounting holes are designed with mounting holes for convenient installation and use. They are widely used in robots and turntables.

Product features

90V,,.,,,P2.,,,,,IC.Cross roller bearings are two columns of cylindrical rollers arranged vertically across each other through nylon isolation blocks on the 90-degree v-shaped raceway, so cross roller bearings can withstand radial load, axial load and torque load. The dimensions of the inner and outer rings are miniaturized, the extremely thin form is close to the limit of the small size, and has high rigidity, the cross roller bearing precision can reach P2 level. It is suitable for joint rotating part of industrial robot, rotating table of machining center, precise rotating table, medical machine, calculator, IC manufacturing device and so on.

Product description of the same series as model RU178

RU(),.,,,..RU type (inner and outer ring type) this series of models have been processed with mounting holes, so there is no need to fix flanges and supports. In addition, because of the integrated inner and outer ring structure with the seat, the installation has little effect on the performance, so stable rotation precision and torque can be obtained. Can be used for outer ring and inner ring rotation.
