About Ever-Power Australia
We engineer and supply precision driven sprockets for the industries that keep Australia moving. Over 15 years of power transmission expertise, 3,200+ SKUs, and a relentless focus on dimensional accuracy and material traceability.
A Full-Range Power Transmission Manufacturer with Deep Sprocket Expertise
We are Ever-Power Australia Driven Sprockets Co., Ltd., a specialist division of the Ever-Power Group focused on the Australian and Asia-Pacific markets. As a full-range power transmission manufacturer producing gearboxes, motors, and a wide variety of mechanical components, we bring complete system-level engineering knowledge to every driven sprocket we supply. We understand how each element in a chain drive train interacts, and we apply that understanding to deliver sprockets that perform reliably under real-world Australian operating conditions.
We maintain an inventory of over 3,200 driven sprocket SKUs covering ANSI and ISO metric standards, with tooth counts from 9 to 120 teeth in simplex, duplex, and triplex strand configurations. We manufacture from carbon steel, alloy steel, stainless steel, cast iron, and engineering plastics. Every sprocket undergoes dimensional inspection and material verification before it leaves our facility.
Our clients include maintenance engineers at iron ore mines in the Pilbara, plant managers at dairy processing facilities in Gippsland, procurement officers at grain handling terminals in regional New South Wales, and production engineers at packaging plants in Melbourne. We serve any operation that depends on roller chain and driven sprocket systems for reliable power transmission.

Top-Demand Lines Safety Stocked
Reduce Downtime. Extend Service Life. Simplify Procurement.
We exist to solve a specific problem for Australian industry: the cost and complexity of sourcing reliable driven sprockets for critical chain drive systems. Every hour of unscheduled downtime at a mine site, processing plant, or agricultural operation has a measurable financial impact. We reduce that risk by maintaining deep inventory on high-demand sprocket lines, providing accurate engineering specifications to prevent ordering errors, and delivering material certification that satisfies audit requirements. We do not make promises we cannot verify. We supply driven sprockets with documented material traceability, dimensional inspection records, and surface treatment certifications because our clients need that documentation to maintain compliance with their own quality management systems.
What Sets Us Apart
System-Level Engineering Knowledge
We do not simply catalogue sprockets. Because we manufacture the full spectrum of power transmission components, including gearboxes, motors, couplings, and bearings, we understand how a driven sprocket interacts with every other element in the drive train. This system-level perspective means we can identify specification issues that a sprocket-only supplier might miss, such as chain wrap angle deficiencies, insufficient shaft stiffness, or material incompatibility between the sprocket and the operating environment. When we recommend a driven sprocket specification, it accounts for the complete system, not just the sprocket in isolation.
Material Traceability and Quality Assurance
Every driven sprocket we supply can be traced back to its raw material source. We provide material test certificates conforming to EN 10204 Type 3.1 for all steel grades, including mill certificates for stainless steel sprockets confirming exact grade composition. Our manufacturing facility holds ISO 9001:2015 certification, and all sprockets are produced to ANSI B29.1 or ISO 606 dimensional standards. Tooth profiles are CNC hobbed, bores are machined with concentricity held to within 0.025 mm TIR, and keyways are broached to AS 1403 / DIN 6885 fit tolerances. We can provide dimensional inspection reports and certificates of conformance for any order on request.
Australian Market Understanding
We have invested years developing our understanding of the specific operating conditions that driven sprockets face across Australian industries. From the extreme heat and abrasive iron oxide dust of the Pilbara to the high-humidity, salt-spray environments of Queensland coastal processing plants, and the cold-start challenges of Tasmanian forestry operations, we know what materials, surface treatments, and hub configurations perform best in each environment. This regional knowledge means we can proactively recommend specifications that will extend sprocket service life in your specific application, rather than simply fulfilling a part number request without context.
Manufacturing and Engineering Capabilities
The processes and equipment behind every driven sprocket we deliver.
CNC Hobbing and Tooth Cutting
We cut tooth profiles on multi-axis CNC hobbing machines to AGMA quality class tolerances. This ensures consistent chain engagement geometry across every tooth on every sprocket, eliminating the uneven wear patterns that occur with less precisely manufactured teeth. We produce both standard involute profiles and custom tooth geometries for special chain types.
CNC Turning and Bore Machining
We machine bores on CNC lathes with concentricity held to within 0.025 mm TIR relative to the pitch circle diameter. This ensures the sprocket runs true on the shaft, preventing vibration and uneven chain loading. We produce finished bores to H7 tolerance as standard, with tighter tolerances available on request for high-speed applications.
Induction Hardening
We harden tooth flanks to HRC 40-50 using controlled induction heating followed by rapid quenching. The core of the tooth remains ductile, providing shock absorption while the hardened surface resists abrasive wear. This treatment extends driven sprocket tooth life by 2-3 times compared to unhardened sprockets, which is particularly important in the abrasive dust environments found in Australian mining and aggregate operations.
Surface Treatment and Coating
We offer black oxide coating, zinc plating, zinc-nickel alloy plating, hot-dip galvanising, hard chrome plating, and electro-polishing. Each treatment is selected to match the operating environment. For example, zinc-nickel plating provides 5-10 times the salt spray resistance of standard zinc, making it suitable for coastal installations, while electro-polishing achieves surface roughness below Ra 0.8 micrometres for food-grade stainless steel sprockets.
Keyway Broaching
We broach keyways to AS 1403 / DIN 6885 fit tolerances, ensuring positive torque transmission between the driven sprocket and the shaft without play or backlash. For applications requiring set screw retention, we drill and tap set screw holes at 90 degrees to the keyway as standard. Custom keyway profiles and multiple keyway configurations are available for specialised shaft arrangements.
Quality Inspection and Testing
We inspect every driven sprocket against its dimensional specification before dispatch. Tooth profile, pitch diameter, bore diameter, keyway dimensions, and overall diameter are measured and recorded. Surface hardness is verified on hardened sprockets using portable hardness testing equipment. Material composition is confirmed through our incoming material inspection process and cross-referenced against the mill certificate for each steel batch.
Materials We Work With
We select material grade based on the operating environment, not the lowest cost option.
1045 Carbon Steel
The standard industrial workhorse. Good strength-to-cost ratio for general manufacturing, packaging, and materials handling applications where corrosion exposure is minimal.
4140 / 8620 Alloy Steel
Higher tensile strength and fatigue resistance for mining conveyors, heavy-duty drives, and applications with shock loading. Case-hardened 8620 provides extreme surface hardness with a ductile core.
SS304 / SS316 Stainless Steel
Corrosion resistance for food processing, dairy, pharmaceutical, marine, and wastewater applications. SS316 provides superior resistance in chlorinated and saline environments along the Australian coastline.
Nylon / POM Engineering Plastics
Self-lubricating, low-noise, chemical-resistant. Used in food-contact zones, clean rooms, and light-duty conveyor systems where metal lubricant contamination cannot be tolerated.
