Automatic Wheel Bearing Mounting Press Bearing Press-Mounting Machine
Overview of Hubei Heqiang:
Hubei Heqiang Machinery is the leading manufacturer of wheel set presses and bearing mount/dismount presses in China. It offers the most advanced wheel set and bearing pressing equipment available in the railway and other relevant industry. The wheelset presses are used to mount and dismount all of the elements on the axle (wheel discs, brake discs, gears). With both single and double cylinder version available for option and capacity range from 200 to 800 tons. The bearing mount/dismount presses are used to mount or dismount the rolling bearings of the wheelsets. With both stationary and mobile version available for option. Our vast range of machines can satisfy all customer requirements in both maintenance and mass production applications.
Application scope:
This Railway Bearing Mounting Press is mainly used for the automatic mounting of whole rolling bearings of various types of railway vehicles.
It can mount the 2 bearings simultaneously. It can generate, record, save and print the pressing curve (Pressure vs displacement, pressure vs time). It's only required one operator to run the press.
