Since the rice transplanter is working in a paddy field, the working condition of the oil-free bearing of the rice transplanter is rather harsh. The soil and sewage working environment makes it difficult to carry out the maintenance of the rice transplanter. Therefore, higher requirements have been put on some wearing parts such as bearings for oil-free bearings of rice transplanters.

According to the working environment of the rice transplanter and the specific requirements of the oil-free bearing of the rice transplanter at different working positions, different products such as bimetal bushings, composite bushings, and graphite bushings can be selected. Compared with ordinary type rice transplanter non-oil bearing such as copper bushing or steel bushing, the performance is superior, the cost is lower, and the cost performance is particularly high.
