Standard catalogue roller chain — simplex or duplex in common ANSI or ISO pitch sizes — can be sourced from many Australian distributors. Custom roller chain is a different matter. Attachment chain with specific plate geometry, sawtooth plate roller chain in non-standard configurations, extended pin chain for conveyor slat mounting, and chain in non-standard lengths for machinery where standard chain cannot be looped without an offset link — all of these require a supplier who can manage a custom specification, communicate it accurately to the manufacturer, and deliver the product with the quality documentation that custom orders require. Knowing who to contact and what information to have ready before making the call significantly accelerates the quotation and production timeline.
When Do You Need a Custom Roller Chain Quote?
The threshold between standard and custom roller chain is straightforward. You need a custom quote when any of the following is true: the chain requires attachment plates (K-type, A-type, or special geometry); the chain requires extended pins at specified link positions; the chain is required in sawtooth plate roller chain configuration not available in standard stock sizes; the chain requires non-standard materials (special stainless grade, high-temperature alloy, food-grade coated); the chain is required in a pre-cut loop of a specific link count rather than from bulk reel; or the chain requires a non-standard connecting link arrangement.
Standard catalogue chain — ANSI or ISO, simplex, standard or heavy series, in common pitch sizes — does not require a custom quote. These items can be ordered from stock through EverPower Roller Chains Australia and despatched within 1 to 5 business days.
What Information to Prepare Before Contacting a Supplier
A custom roller chain quotation requires specific technical information to be accurate. Keeping this information ready before contacting a supplier dramatically reduces the back-and-forth that otherwise delays the quotation. The minimum information required for a custom chain quote is:
| Information Required | Why It Matters | How to Obtain It |
|---|---|---|
| Chain standard | Determines all base dimensions — wrong standard means wrong sprocket fit | Measure existing chain roller diameter and inner width; cross-reference against ANSI/ISO tables |
| Chain number / pitch size | Identifies the base pitch and series | Read from chain plate marking or measure and calculate from tables |
| Strand count | Simplex, duplex, or triplex affects plate spacing and sprocket requirement | Count strands on existing chain or specify based on load calculation |
| Standard or heavy series | H suffix for heavy series — determines plate thickness | Measure plate thickness at mid-plate and compare to ANSI table |
| Required length (in links or metres) | Custom pre-cut loops must be specified exactly | Count links in existing loop or calculate from drive geometry |
| Attachment description | Location, type, and geometry of any attachment plates or extended pins | Provide drawing or photograph of existing attachment or sketch of required geometry |
| Connecting link type | Spring clip, cottered, or riveted — affects retention in service | Specify based on application shock level and access for maintenance |
| Quantity required | Affects pricing and whether stock or new production is required | State total length required including any spare sections |
The Custom Chain Quotation Process at EverPower
EverPower Roller Chains Australia manages custom roller chain quotations through a structured process that minimises lead time and specification errors. When you contact our Sydney team with a custom requirement, the process follows four stages:
Stage 1 — Specification Review (Day 1–2)
We review the technical specification you provide, identify any gaps or ambiguities, and verify the complete specification in writing before any order is placed. This stage eliminates the most common cause of custom chain production errors — ambiguous specifications.
Stage 2 — Supplier Confirmation and Pricing (Day 2–5)
We verify production feasibility, lead time, and pricing with our qualified supplier network. For complex attachments, we may request a sample drawing or 3D model from the supplier for your approval before production commences.
Stage 3 — Sample Approval (Where Required)
For new attachment geometries or complex custom configurations, we arrange a first-article sample before full production. This adds 2 to 4 weeks to the total lead time but eliminates the risk of receiving a full production quantity of incorrect chain.
Stage 4 — Production and Delivery
Standard custom chain production ex-factory: 4 to 8 weeks from confirmed specification. We arrange quality documentation (dimensional inspection report, material certificate) for each consignment and manage international freight and Australian customs clearance.
Lead Times for Custom Roller Chain
Custom roller chain lead times depend on the complexity of the specification and whether the base chain body is a stock item at the manufacturer. For custom pre-cut loops in standard pitch sizes where only the length differs from standard: 2 to 4 weeks. For attachment chain using standard attachment plate types (K-type, A-type) in standard pitch sizes: 4 to 6 weeks. For fully custom attachment geometry requiring tooling or special plate blanking: 8 to 14 weeks including first-article approval. For specialty materials (high-temperature alloy, special stainless grades): add 2 to 4 weeks to the above timelines.
Planning ahead is the most effective tool for managing custom chain lead times. For machines with known chain replacement intervals — such as agricultural roller chain on combine harvesters replaced pre-season — ordering custom chain 10 to 14 weeks before the required delivery date eliminates any lead time pressure. For machines with unpredictable replacement timing, maintaining a pre-approved specification on file with EverPower allows us to initiate production quickly when the need arises.
Sawtooth Plate and Heavy Series as Custom Specifications
Sawtooth plate roller chain and heavy series chain in standard pitch sizes are stocked by EverPower for immediate despatch in the most common sizes. For less common pitch sizes or for sawtooth plate chain in duplex configuration, these may be treated as custom orders with the lead times described above. Contact our Sydney team to check current stock availability before assuming a custom order is required — we may be able to supply from existing stock faster than a custom production timeline.
