WY J2 - Bearing Press-Fitting Machine is mainly used for non-axle box rolling bearing press fitting of railway EMU, passenger cars, light rails and metros. It is controlled by the computer which can automatically generate press-fitting curve and can determine whether the result is qualified or not, the press-fitting process data can also be recorded automatically. The main oil cylinder adopts double-cylinder compound cylinder structure. The internal cylinder is used for accurately positioning the bearing during press-fitting, and the external cylinder is for bearing press-fitting. The entire press-fitting process is completed on the equipment axis. The press-fit cylinders are press-fit separately at both ends, synchronized and adjustable in speed. Both ends can work independently, automatically or manually step-by-step. Provide cloud-based remote data collection solutions to better serve users.
