Machined Sprockets Built for Industrial Performance
Every Renold chain sprocket is engineered for optimal tooth engagement with our transmission chain range—including the high-performance Renold Sovereign and Renold Synergy series. That means longer wear life, reduced chain elongation, and less unplanned maintenance.
Our machined sprocketsare available in simplex, duplex, and triplex configurations to suit standard transmission chains, with pitch sizes available up to 2 inches. Bore options include finished bore, taper lock, and pilot bore to suit your shaft setup. Every sprocket is precision-machined from quality steel to ensure accurate pitch diameter and reliable power transmission across various applications.
If you’re searching for a dependable industrial chain manufacturer that also supplies matched sprockets, Renold’s Auckland-based team can specify the right sprockets for your drive.
Custom Sprocket Manufacturer for Specialist Applications
Standard off-the-shelf sprockets don't always fit the job. As an established custom sprocket manufacturer with in-house design and machining capability, Renold produces special sprockets for specific applications in harsh or demanding drive situations. Our range includes:
- Necklace sprockets for turning large drums or tables
- Combination sprockets with different pitch sizes and tooth counts on a single hub
- Split sprockets and segmental sprockets for installations where shaft removal isn't practical
- Stainless steel sprockets in 304-grade and 316-grade for corrosive, washdown, or food-grade environments
- Sprockets in non-standard materials for high-temperature or chemically aggressive conditions
Our engineering team works directly with mechanical engineers, maintenance teams, and procurement professionals to deliver machined sprockets that match exact application requirements, from initial CAD design through to finished component.
Sprocket Accessories and Chain Drive Support Tools
We also offer a wide range of accessories, such as chain wear guides and chain pin extractors. Renold's chain wear guides let you measure chain elongation on-site without removing the chain, so you can plan industrial chain sprocket and chain replacements before unplanned downtime hits.
An innovative chain tensioner can also be easily installed where space limitations prohibit the use of conventional chain tensioners. This is especially useful in retrofit applications or compact drive layouts common in New Zealand’s food processing and timber industries.
Need Help Selecting the Right Industrial Chain Sprocket
Our NZ-based engineering team can review your application and recommend the right sprocket, whether that’s a standard machined sprocket set or a custom solution for a one-off application.

Frequently Asked Questions
How do I know when to replace a worn sprocket?
When a roller chain reaches approximately 2% elongation over its nominal pitch length, both chain and sprockets should be replaced together. Running a new chain on worn sprockets accelerates wear and significantly shortens chain life.
Renold's free chain wear guide makes it easy to check elongation without removing the chain from the drive.
Can Renold manufacture custom roller chain sprockets for non-standard applications?
Yes—Renold is an established custom sprocket manufacturer with in-house machining at our Auckland facility. We produce split sprockets, combination sprockets, necklace sprockets, and sprockets in specialist materials to suit specific drive requirements across New Zealand industries.
What grades are available for stainless steel sprockets?
In food and beverage processing, water treatment, and chemical handling, standard carbon-steel sprockets corrode and fail fast. We supply stainless steel sprockets in 304-grade as a standard, with 316-grade available for more aggressive chemical or machine environments.
Both options suit food-grade washdown and corrosion-prone applications common throughout New Zealand.
