Precision Spacers & Rings

Slitting line setup

Precision spacers and rings locate slitting knives axially and build the required tooling widths, using thin shims, thicker spacers and locating bushes. Selection should relate target strip width, knife thickness and the complete stack sequence to arbor fit, end-face condition and inspection method. Individual thickness tolerance is only one part of this review; it should not be treated as a direct statement of the strip-width accuracy achievable by the assembled slitting line.

Axial positioning: Review stack dimensions with knife thicknesses and the required finished strip widths.
Complete-set review: Assess thin shims, thick spacers and locating bushes as one tooling arrangement.
Inspection definition: Distinguish individual thickness requirements from the cumulative dimensions of the stack.

Where this product works

Matched slitting-line tooling

Spacers set the axial positions of the knives. Review the complete stack, knife thickness and arbor interface rather than an isolated ring.

Equipment photographs show application context only; the supply scope on this page is the listed tooling or components, not complete machines.

Keep the knife setup aligned with the cut

Spacers establish the axial positions of circular knives. Configurations include thin shims, thick spacer bushes and grouped sets for strip-processing applications.

40CrMo is a material option subject to application review. Heat treatment, finishing, demagnetisation, stack dimensions, surface condition and tolerances must be agreed for the actual arbor and tooling setup.

Typical configurations

Precision cutter shims and thin spacers
Locating bushes and thick spacer sets
Lightweight spacer configurations; confirm suitability for the tooling setup.
Matching support and stripper rings: confirm the exact configuration

APPLICATIONS

Typical applications

Slitting-tool width setups

Spacers combine with circular knives to build strip-width arrangements. Provide upper/lower sequences, knife thicknesses and target widths so every spacer position can be reviewed, rather than only the total stack length.

Thin-shim adjustment

Identify adjustment positions, thickness series and quantities when shims are used in an existing stack. Describe cleaning and measurement practices so inspection requirements can be agreed for the actual application.

Locating and companion rings

Locating bushes, support rings and stripper rings perform different tasks. Mark positions and contact surfaces on the assembly; distinguish coated rings from solid-metal spacers when defining construction and fit.

SELECTION NOTES

What to check before selection

Use the full stack layout: List each ring and knife by identifier, thickness, order and quantity, with assembly datums. Different combinations with the same overall length may still have different locating and adjustment requirements.
Check interfaces and end faces: Review bore, OD and end faces with the arbor, adjacent knives and clamping arrangement. Record marks, dents or deposits; thickness alone does not establish the condition of an existing part.
Agree measurement and tolerances: Specify individual thickness, thickness consistency and total stack dimensions separately, including measurement datums and acceptance methods. Special precision requires drawing and quotation review rather than direct adoption of an example specification.

Product images are for reference. Final dimensions, materials and acceptance criteria are subject to the confirmed drawing and quotation.

PRACTICAL QUESTIONS

Practical selection questions

Clarify the operating conditions and interfaces before deciding on materials, geometry or configuration.

Is total spacer thickness enough to define a complete set?

No. Each position also requires knife thickness, order, target strip width and quantity. A setup sheet or assembly sketch allows the individual combinations to be reviewed rather than inferred from total thickness.

Does a tight individual tolerance establish accurate strip widths?

Not directly. Cumulative dimensions, end-face cleanliness, knife thickness and arbor condition may also affect width. Separate individual inspection from complete-stack setup and check the measurement method used on site.

Can solid-metal spacers and coated rings interchange by size?

First identify whether each part locates, supports or strips the material. Review its contacts and construction; equal external dimensions do not establish equal function. Provide assembly positions and existing-part images.
