Description
What Are Bonded Rubber Stripper Rings?
Bonded Rubber Stripper Rings are critical components installed between slitting knives and spacer rings on metal slitting lines.
Manufactured with a hardened alloy steel core bonded to a high-performance elastomer outer layer, they help maintain stable strip processing throughout the slitting operation.
Their primary functions include:
- Material stripping
- Strip tension control
- Surface protection
- Vibration damping
- Stable strip tracking
- Coil winding stability
The performance of stripper rings directly affects:
- Surface quality
- Strip stability
- Recoiling quality
- Tool life
- Production efficiency
