Cross roller bearings or alternative YRT turntable bearings

August 09, 2018

As we all know, the overall quality of domestic high-precision processing equipment and industrial workers is still far from that of foreign countries. This is why the domestic production of YRT turntable bearings has been unstable, it is difficult to meet the main requirements of the user, which is bound to cause YRT Turntable Bearing high rejection rate, production costs increased significantly, production cycle is too long, and it is difficult to form mass production, and the cross roller bearings precisely make up for the defects of YRT turntable bearings in these areas, the structure is relatively simple, production and processing The process is simple, the requirements for production equipment are low, and it is relatively easy to achieve high accuracy, and can quickly form a batch production capacity, the production cycle is relatively short, and the cost is significantly reduced relative to YRT turntable bearings.

Cross-roller bearings and YRT turntable bearings have many similarities in terms of function and use, such as high rigidity, high precision, high load-carrying capacity, and high-speed performance in terms of performance. They are widely used and highly accurate in their use. CNC dials, vertical machining centers, vertical grinding machines and other equipment, cross roller bearings and YRT turntable bearings are not very different in terms of function and use.

However, the Cross Roller Bearing in other aspects has the advantage that the YRT rotary table bearing can't be surpassed. Firstly, compared with the cross Roller Bearing and the YRT rotary table bearing in the same size segment, the cross roller bearing structure is relatively simple, through a row The cylindrical rolling elements arranged on a single raceway cross each other can obtain considerable axial and radial bearing capacity and overturning moment, while the YRT turntable bearings must be arranged in three rows of rolling paths through three rows of cylindrical rolling bodies. In order to achieve the same effect, this brings great inconvenience in production and processing. Compared to the single-row raceway of the crossed roller bearing, the production and processing complexity of the YRT turntable bearing is greatly increased, and the difficulty is also greatly improved. The quality of production and processing equipment and production personnel put forward high requirements.

For users, the cost performance of cross roller bearings is much higher than that of YRT turntable bearings, which is why cross roller bearings gradually replaced YRT turntable bearings in recent years. It can be imagined that in the near future, high precision Cross roller bearings will replace YRT turntable bearings in a wide range.
