What are the characteristics of roller guide shoes?

Whether the shoe lining of rigid sliding guide shoes or elastic sliding guide shoes is made of iron or nylon lining, there is still a significant frictional force between the shoe lining and the guide rail during elevator operation. This frictional force not only increases the load on the traction machine, but also is one of the causes of vibration and noise during the operation of the elevator car. In recent years, roller guide shoes have been used in elevator products to reduce friction between guide rails and shoes, save energy, and improve ride comfort. The roller guide shoe is mainly composed of two side guide wheels and one end guide wheel. The three rollers clamp the guide rail from three aspects, allowing the car to run up and down along the guide rail. When the car is running, the three rollers roll simultaneously to keep the car running in a balanced state. In order to extend the service life of the roller and reduce the noise generated during rolling friction between the roller and the guide rail working surface, the outer edge of the roller is generally made of wear-resistant plastic material and does not require lubrication during use like sliding guide shoes.
