The pressure roller product has a diameter of 60mm and a height of 55mm. It is equipped with 6202 bearings. This bearing model has high load-bearing capacity and rotation speed and is suitable for escalator roller application scenarios. The use of CPU (a high-performance plastic material) can maintain stable physical and chemical properties for a long time and extend the service life of the rollers; the rollers use high-quality bearings and materials, which have strong load-bearing capacity and can meet the needs of different loads of the escalator. operating requirements under the conditions.
