Mobile Rolling Bearing Mounting & Dismounting Machine
1. Brief Description
The Mobile Rolling Bearing Pressing and Dismounting Machine is used for the pressing and dismounting of rolling bearings in wheel set axle boxes of railway locomotives and rolling stock. It is mainly suitable for operations on new manufacturing and maintenance lines, especially in temporary sites or on-site working conditions.
The machine features stable pressing and dismounting, impact-free bearing handling, flexible movement, small footprint and convenient operation. It fully meets the requirements for bearing pressing and dismounting of wheel set axle boxes for railway locomotives and rolling stock.

3. Structure composition：
The equipment mainly consists of seven parts:mobile trolley,hydraulic power unit,lifting cylinder, pressing and dismounting cylinder, pressing tooling, dismounting tooling, electric control box.
4. Structure features:
· Equipped with a movable trolley, free from site and location restrictions.
· One machine performs two functions (pressing & dismounting), reducing investment cost.
· Stable and reliable performance with easy operation.
· Lifting cylinder enables convenient vertical alignment.
· Manual operation for bearing pressing and dismounting is simple and user-friendly.
· Compatible with various bearings by quickly changing tooling.
· Pressing and dismounting pressure can be easily adjusted according to working conditions.
· Equipped with pressure sensor to display real-time pressing and dismounting force.
· Cylinder center aligns with wheel set center during operation, avoiding workpiece damage.
· Dismounting force is applied evenly on the rear baffle end face, protecting bearings and axles without deformation.
· Dismounting claws are located under the bearing, preventing bearings from falling to the ground for easy removal.
· Lower-positioned dismounting claws avoid collision damage to the cylinder piston rod.
· High working speed and efficiency, with a cycle time of about 4 minutes per operation.
· Adaptable to wheel set bearing pressing and dismounting for various track gauges.
