Location of Nuts
- Rolling and straightening arbors/mandrels to retain roll sections
- Tie-rod pre-stress nuts to hold sectional mill frames together
- Forming roll bearing lock-up in chocks
- Circular friction cut-off saw blade flanges
Benefits of Hydraulic Lock-up
- Maintains positive lock-up and alignment for rolling, straightening and cut-off stands
- Eliminates the need for jam nuts or repeated re-tightening of mechanical nuts
- Replaces “superbolts” (multiple axial jack screws) with a faster and more reliable lock-up system
- Quick release and removal
- Maintains a tight sectional mill frame by exceeding separational forces
- Optimizes roll end-float by controlling bearing location
- Net benefit: improved product straightness and section thickness with more runtime
Type of nuts: GX-Type, Block Nuts, Step Nuts (custom designed).
