DIN 8187 / ISO Compliance

Every 06B sprocket conforms to DIN 8187 and ISO/R 606 tooth-form geometry, ensuring drop-in compatibility with all compliant 06B roller chains. No modification or shimming required — the chain seats and runs true from day one, reducing commissioning time and the risk of misalignment-induced wear.

C45 Steel with Heat Treatment

C45 medium-carbon steel gives the ideal balance of machinability and post-hardening surface hardness. Induction-hardened tooth flanks resist the Hertzian contact stress of repeated roller impact, extending service life well beyond that of mild-steel alternatives — a critical advantage in high-cycle conveyor and packaging applications.

Z=8 to Z=125 Full Range

From compact 8-tooth sprockets for tight-centre drives to 125-tooth wheels for slow, high-torque applications, the complete tooth-count range is available. This breadth means procurement teams can source their entire 06B sprocket requirement from a single supplier, simplifying logistics and reducing lead-time risk across maintenance projects.

Custom Bore Machining In-House

Standard pilot bores are machined to your exact shaft diameter, with keyways, set-screw flats and stepped bores all executed in-house. Whether you need a 12 mm bore for a motor shaft or a 50 mm bore for a heavy gearbox output, Ever Power delivers a finished component — not a blank requiring further workshop time on your side.

Simplex, Duplex & Triplex Stocked

06B-1, 06B-2 and 06B-3 configurations address single, double and triple-strand chain drives respectively. Duplex and triplex variants multiply power capacity without increasing chain pitch or sprocket diameter, making them the preferred solution where installation space is limited but load requirements are growing — common in upgraded production lines across UK manufacturing.

UK-Ready Despatch & Export

Stock items typically despatch within 2–5 working days to mainland UK addresses, with express options available. Full documentation — material certificates, dimensional inspection reports and DIN compliance statements — is supplied on request, satisfying the requirements of ISO 9001-managed procurement and regulatory frameworks across UK and export markets.

▶  Material & Heat Treatment

C45 steel — a European standard medium-carbon grade equivalent to EN8 — provides the core toughness needed to resist shock loading during chain engagement. The heat treatment cycle creates a hardened surface layer on the tooth flanks while retaining a tough core, resulting in a sprocket that resists both surface pitting and bulk fatigue fracture. This is particularly valuable in intermittent-duty applications such as packaging line indexing, where each cycle starts and stops the chain abruptly. Finished surfaces are protected against corrosion by controlled oil preservation or zinc phosphate coating, depending on the application environment specified at the time of order.

▶  How the 06B Sprocket Works

Power transmission via roller chain is a positive-engagement mechanism — there is no slip under normal operating conditions. The 06B roller, with its 6.35 mm diameter, seats in the tooth gap defined by the root circle and the flanking involute profile. As the sprocket rotates, each roller is captured and released in a controlled sequence, creating the rotational-to-linear motion transfer that drives conveyors, lifts, feeders and indexing tables. The pitch circle diameter (dₚ) governs the velocity ratio between driver and driven sprockets, while the tip diameter (dₚ) determines how close adjacent components can be installed. Maintaining the correct chain tension in the drive is critical — excessive sag allows the chain to jump teeth on small-tooth sprockets, while over-tension accelerates both chain and sprocket wear.

▶  Typical Application Sectors

The 06B sprocket is found in an exceptionally broad range of British industrial sectors. Food and beverage processing lines rely on its compact pitch for hygienically accessible conveyor drives. Agricultural machinery manufacturers in the East Midlands and Yorkshire use it in seed and fertiliser handling equipment. Automated warehousing and e-commerce fulfilment centres across the Midlands specify it for tote conveyors and sorter drives. Textile machinery, printing equipment, medical device manufacturing lines and light engineering automation all benefit from its combination of small footprint and reliable power transmission capacity. Its compatibility with standard 06B chain from multiple chain suppliers means the complete drivetrain is readily sourced, inspected and replaced by UK maintenance teams without specialist tooling.

We’ve been fitting Ever Power 06B sprockets on our automated palletiser line for two years. The tolerances are consistently tighter than what we’d been getting from our previous supplier, and we haven’t had a single premature failure since the switch. The custom bore service is genuinely useful — no more waiting days for the workshop to finish boring out a blank.

Sourcing 06B triplex sprockets with weld-on hubs used to be a real headache. Most suppliers only stock simplex. Ever Power had the duplex and triplex variants in the tooth counts I needed, quoted within hours and had them on a pallet the following week. Material certs came with the delivery — exactly what our quality system requires.

Price was competitive with UK distributors and the lead times were shorter than I expected for a fully machined bore. The Z=19 and Z=21 sizes we ordered aren’t held by anyone locally, so being able to get those from Ever Power with a full dimensional report made our ISO audit much simpler. Will be using them as our standard 06B source going forward.

What is the pitch and roller diameter of a 06B sprocket compatible with DIN 8187 chain?

The 06B sprocket is engineered for chain with a pitch of 9.525 mm and a roller diameter of 6.35 mm, both defined by DIN 8187 and ISO/R 606. These values determine the tooth root radius and pitch circle diameter, so it is important to confirm both the pitch and roller size when selecting a replacement sprocket — particularly when working with chain from different manufacturers or replacing an older installation where the original specification documentation has been lost.

Where can I buy a high-quality 06B-1 simplex sprocket with a custom bore size for industrial use in the UK?

Ever Power supplies finished, custom-bored 06B-1 simplex sprockets to industrial buyers across the UK. You can specify your exact bore diameter, keyway dimensions and tolerance requirements at the time of enquiry. Contact [email protected] with your shaft drawing or just the key dimensions — bore size, keyway width and depth, and the number of teeth required — and you will receive a quotation within one working day.

What is the typical price of a 06B duplex or triplex sprocket for a food processing line in England, and how do I get a quote?

Pricing depends on tooth count, configuration (06B-2 duplex or 06B-3 triplex), bore specification and order quantity. Standard stock items are generally priced more competitively than custom specials. To get an accurate price for your food processing line application, email [email protected] with the tooth count, the bore diameter, and whether you need the weld-on hub variant. Volume discounts are available for regular or blanket orders.

Which tooth count should I choose for a 06B sprocket on a conveyor drive running at moderate speed in a UK warehouse?

For moderate-speed conveyor drives, a tooth count in the range of Z=17 to Z=25 is generally recommended. More teeth mean a larger pitch circle, which reduces the polygonal effect (the slight speed variation that occurs as each roller engages a tooth) and lowers chain noise and vibration. For the small sprocket in a two-sprocket drive, Z=19 or Z=21 is a practical choice. The large sprocket tooth count is then chosen to achieve the desired speed ratio. Our application engineers can assist with drive selection calculations at no charge — just provide the motor speed, chain speed or conveyor belt speed, and the approximate centre distance.

How long does delivery of 06B sprockets from a UK supplier typically take, and is express despatch available?

Standard stock items in common tooth counts typically despatch within 2–5 working days. Custom-bored items generally add 3–7 working days depending on bore complexity and current workshop loading. Express despatch is available for urgent breakdown situations — contact us directly by email with your requirement and we will advise on the fastest available option. For customers who experience frequent call-offs of the same part numbers, a consignment or call-off stock arrangement can be set up to ensure next-day availability at all times.

Can I get a custom-bored 06B triplex sprocket made to fit a legacy packaging machine that no longer has its original technical drawings?

Yes — this is a straightforward service for Ever Power. If you can provide the shaft diameter, keyway dimensions (measured directly from the shaft or an existing key), and the tooth count (or the pitch circle diameter from which we can calculate the tooth count), we can produce a finished replacement sprocket. Alternatively, if you can send a worn or damaged sample, our metrology team will reverse-engineer the key dimensions and confirm the specification before machining begins. This process is used regularly by UK maintenance teams working on older imported equipment where original documentation is unavailable.

What material is used in a quality 06B sprocket and how does C45 steel heat treatment affect wear life in heavy-duty UK industrial applications?

Ever Power 06B sprockets are manufactured from C45 medium-carbon steel, equivalent to EN8 in the British Standard nomenclature. After machining, the tooth flanks are induction-hardened to create a wear-resistant surface layer — typically 52–58 HRC at the surface — while the core remains at a lower hardness (approximately 180–220 HB) to absorb shock loads without brittle fracture. In continuous-duty applications such as bottling conveyor drives or pallet handling systems, this hardness profile means the tooth flanks resist the micro-pitting and surface fatigue that eventually cause soft-tooth sprockets to develop hook-shaped wear profiles and begin skipping under load. The practical outcome is a service life typically three to five times longer than untreated mild steel sprockets operating in the same conditions.
