Roller Major technical parameters:

Roller resistance to rotation

The amount of radial run-out

 Roller Axial load

Roller'S Axial float

Under the impact of axial load of 500N,the axial float figure≤1.2mm

Roller Dropping intensity

After experiments of horizontal and vertical drop of carrier roller,the following requirements should be met:

• All components and welded joints cannot be damaged or taken apart;
• Axial displacement of roller carrier after falling should be not more than1.2mm;
• The body and bearing of carrier roller should never be loosing;
• The resistance to rotation should be not more than1.5 times of the figure stipulated in table 1.

Roller Sealability in water

After revolving at the rate of 1450t/min for 24 hours in water,the water inflow of the carrier roller with non-contact seal device is not more than150g.
