Roll Cassettes

Precision Roll Cassettes for Tension Levelers in Sheet and Strip Production

Roll cassettes are the backbone of a tension leveler. They support work rolls and intermediate rolls and prevent deflection during high speed operation, which is why cassette specification decides both the precision and the durability of sheet and strip processing.

  • Surface quenching up to HRC 63-65
  • Chrome plating around 0.05 mm
  • Hardened layer around 5 mm
  • Used from automotive manufacturing to construction

Key Benefits

What a precision cassette changes.

Deflection Prevented At Speed

Supporting work and intermediate rolls prevents deflection and deformation during high speed operation, which is where flatness is won or lost.

Hardness Where It Counts

Surface quenching up to HRC 63-65 with chrome plating gives the contact surfaces the hardness needed for continuous duty.

Production Efficiency

Cassettes that hold geometry keep production efficiency up rather than forcing speed reductions to protect quality.

Where It Is Used

Industries served.

  • Automotive sheet manufacturing
  • Construction sheet and strip production
  • Appliance panel production
  • General metal sheet and strip processing

Who It Is For

  • Tension leveler operators
  • Maintenance teams replacing worn cassettes
  • Machine builders specifying cassettes
  • Buyers upgrading cassette hardness specification

Problems It Solves

  • Roll deflection at high line speed
  • Cassette wear reducing leveling precision
  • Downtime from cassette related failures
  • Inconsistent cassette quality between suppliers

Technical Features

Technical specification.

High Surface Hardness

Surface quenching reaches HRC 63-65 on the working surfaces with a hardened layer around 5 mm.

Chrome Plated Surfaces

Chrome plating around 0.05 mm lowers friction and resists wear on the contact faces.

Support Function By Design

The cassette is engineered to support work rolls and intermediate rolls as a single rigid assembly.

Materials

  • Alloy steel cassette frame
  • Surface quenched roll bodies
  • Chrome plated contact surfaces

Manufacturing Process

Cassette Survey

Roll count, diameters and cassette envelope are confirmed from drawing or sample.

Frame Machining

The cassette frame is machined so roll seats hold alignment under load.

Roll Treatment

Roll surfaces are quenched to HRC 63-65 and chrome plated.

Assembly And Verification

The cassette is assembled and roll alignment verified before packing.

Quality Control

  • Hardness testing to HRC 63-65
  • Plating thickness measurement
  • Roll alignment inspection on assembly
  • Dimensional records issued with the cassette

Customization Options

  • Roll count and diameters per your machine
  • Hardness and plating specification by strip material
  • Quick change interface where available
  • Spare cassettes for rotating maintenance

Use Guide

  • Keep a spare cassette so service happens off line
  • Check alignment after each rebuild
  • Replace rolls within a cassette as a set
  • Clean and protect cassettes removed from the line

How It Compares

Against lower specification cassettes.

Cassettes without surface quenchingHRC 63-65 surfaces resist the wear that softer cassettes accumulate within a single campaign.
Unplated cassette rollsChrome plating lowers friction and protects surface quality on the strip.
Rebuilding in placeExchange cassettes move the work off the critical path and restore alignment fully.
FAQ
