Multi-roll mill / Sendzimir mill backup rolls
Cylindrical roller backing bearing
Required Performance and Issues
1、 Special steel and special heat treatment processes are used.
2、Bearings are processed and manufactured with high precision.
3、Product details have been optimized and improved based on customer feedback.
Open SD Backing bearings
The bearing for multi-roll mill is mounted on the support roller while the outer diameter contacts the intermediate roller. The backing bearing bears the rolling force when rotating.
Sealed SD Backing Bearings
Therefore, the outer ring needs to have sufficient rigidity and fatigue strength. In addition, the bearing is manufactured with high precision. The seal is an optimized oil seal for easy disassembly and maintenance.
(Intracavity pressure :2500~4000 pa).
Optimized load distribution
Variation between two adjacent bearings on one shaft ≤0.002mm(2μ)
H-value Management
Variation of bearing section heights on one shaft ≤0.006mm(6μ)
Seal Plate
Prevents intrusion of rolling-mill water.
Oil seal rotates together with outer ring.
