WB12k-120*4000mm Symmetric Plate Rolling Machine/ W11 Mechanical Type 4Rollers Rolling and Bending Machine/Pipe Forming Machine 

1. Remaining straight edge is small
2. High rolling efficiency and accuracy and high checking circle precision
3. Due to the increase of the bottom roll,one-time plate feeding through program control can be realized the automatic pre-bending,roll forming,operating skills of the operator's requirements is not high
4. Due to the increase of the bottom roll,and both ends of the roll can be separately lifted and dropped,so in the stagger side and defect size can be easily corrected,and high efficiency.
5. Work roller bearings are self-aligning roller bearings,small friction resistance,short power loss,long service life,low energy consumption.
6. Synchronous lifting and dropping of the bottom roll and the lateral rolls,the control and adjustment of the title amount for cone rolling, and the workpiece are automatically controlled by the numerical control system,and the control precision is high
7. The CNC system for the company's independent research and development,with screen display,volume calculation,program control,process parameter storage,software protection and fault alarm,man-machine dialogue and other functions.
8. Frame patent 4-roll machine(ZL20122048.7),new frame has the advantages of reasonable structure, does not need to remove the top roll and meanwhile easily remove and replace both sides rolls, conveniently assembly lateral rolls parts

According to the different bearing series and sizes, there are two different designs. The seal ring is made of stamping steel, usually with a cylindrical extension at the inner diameter of the sealing ring, forming a long sealing gap with the inner ring shoulder. Some seals do not extend.

Bearing with low friction seal ring: the suffix is RSL, 2RSL or RZ, 2RZ, according to different bearing series and size, it also has different structural design.A very narrow gap to form a cylindrical surface or the inner concave contour of the sealing ring and the inner ring shoulder, is actually not contact, therefore, a low friction bearing seal and bearing with Z can run the dustproof cover at the same speed, but its better sealing performance.

Bearing with contact seal ring, the suffix is RSH, 2RSH or RS1, 2RS1
