High-Precision Polyurethane (PU) Stripper Rings for Metal Slitting Lines

SZJL Cutting Tools manufactures premium Rubber Stripper Rings and Polyurethane (PU) Composite Stripper Rings for high-performance metal slitting lines.

Designed to provide stable strip control, vibration damping, and scratch-free material handling, our stripper rings combine a hardened alloy steel core with high-quality oil-resistant polyurethane to achieve excellent durability and precision.

Widely used in steel service centers, stainless steel processing plants, aluminum coil slitting lines, copper strip production, and electrical steel processing.

Description

What Are Rubber Stripper Rings?

Rubber Stripper Rings are essential components in metal slitting lines.

Installed between slitter knives and spacers, they perform several critical functions:

  • Material stripping
  • Strip tension control
  • Surface protection
  • Vibration reduction
  • Stable strip tracking

Proper stripper ring performance directly affects:

  • Strip quality
  • Surface finish
  • Slitting accuracy
  • Production efficiency

Composite Construction

Hardened Alloy Steel Core

Manufactured from premium alloy steel.

Features:

  • High rigidity
  • Excellent dimensional stability
  • Long service life
  • Precision ground surfaces

Premium Polyurethane Outer Layer

Manufactured from high quality oil-resistant polyurethane.

Advantages:

  • Excellent wear resistance
  • Superior elasticity
  • Oil and coolant resistance
  • Stable long-term performance

Key Features

Scratch-Free Surface Protection

Mirror-finished polyurethane surfaces prevent:

  • Surface scratches
  • Roll marks
  • Material contamination

Ideal for:

  • Stainless Steel
  • Aluminum Coil
  • Copper Strip
  • Pre-painted Coil
  • Coated Materials

Superior Strip Stability

Maintains consistent strip tension throughout production.

Benefits:

  • Reduced strip wandering
  • Improved recoiling quality
  • Better dimensional consistency

Vibration Damping

The composite structure absorbs micro-vibrations generated during slitting.

Benefits:

  • Extended knife life
  • Reduced machine wear
  • Improved strip quality

High-Speed Performance

Designed for modern high-speed slitting lines.

Provides:

  • Stable material feeding
  • Accurate strip separation
  • Reliable operation at high RPM
