Application:
| 1. Any striking on and collision with roll rings is strictly prohibited. |
| 2. When installing the whole assembly of roll rings, the clearance of the bearings in relation to the casings should be on the tighter side . |
| 3. The precision of rotation of the whole assembly ( circular runout and end runout ) should be kept within ±0.05mm. |
| 4. The fitting -in of the whole assembly and the roll rings shall be a transitional fitting -in and fastened. |
| 5. The roll rings should not be cooled by water or oil water emulsion. |
Competitive Advantage:
We have three factories directly (steel plant, forging plant, machine processing factory), control the
entire production process, greatly reduce the production cost and circulation costs, can provide
cheap and fine products to our customers.
