About Ever-power
We are a precision Oldham coupling manufacturer with over 20 years of engineering experience, serving B2B customers and OEM partners across 40 countries worldwide.
Precision Coupling Engineering, Built Over Two Decades
We are Ever-power — a dedicated OEM manufacturer of Oldham-type shaft couplings serving machine builders, automation integrators, and industrial distributors worldwide. Our company was founded on a single conviction: that the three-piece Oldham coupling is one of the most elegant solutions in mechanical power transmission, and that manufacturing it to a consistently high standard requires engineering knowledge, precise production equipment, and a rigorous quality system working together.
Over more than two decades we have refined every aspect of our manufacturing process — from raw aluminium alloy selection and CNC machining parameter optimisation through to disc polymer sourcing and dimensional verification methods. That accumulated knowledge is embedded in every coupling we ship.
Our customers range from single-engineer start-ups building their first servo-driven prototype to multinational machine OEMs placing annual blanket orders. We apply the same engineering care to a 10-piece sample order as we do to a 10,000-unit production run.
- In-house CNC turning, milling, and anodising — no outsourced machining
- ISO 9001:2015 certified quality management system
- CMM dimensional inspection on every production batch
- 3D STEP files and datasheets supplied as standard
- OEM private-label programmes for distributors
OEM Experience
Two Decades of Growth in Precision Coupling Manufacturing
From our first production lines to a globally recognised OEM supply partner — a look at the milestones that shaped Ever-power.
Foundation and First Production Line
We established our first machining facility focused entirely on precision Oldham coupling production, investing in CNC turning and milling equipment calibrated for high-repeat bore tolerances in aluminium alloy.
First International OEM Contracts
We secured our first export supply agreements with machine builders in Europe and Southeast Asia, establishing the documentation, packaging, and Incoterms procedures that remain the backbone of our B2B export operations today.
ISO 9001 Certification Achieved
We completed our first ISO 9001 certification audit, formalising the incoming material inspection, in-process CMM verification, and traceability documentation that had been part of our internal practice since the beginning.
Product Range Expansion
We extended the Oldham coupling portfolio to include the SL compact series and WH wide-hub series, broadening our coverage into medical device, semiconductor handling, and high-torque packaging drive applications.
North American and Australian Market Entry
We formalised distribution partnerships in North America and Australia, building the logistics, documentation, and after-sales support infrastructure required to serve these demanding industrial markets consistently.
Private Label Programme Launch
We introduced a structured OEM and private-label programme, allowing qualified distributors to carry Oldham couplings under their own brand identity with consistent dimensional specification and custom part numbering.
ISO 9001:2015 Recertification and Capacity Growth
We completed recertification to the current ISO 9001:2015 standard and invested in additional multi-axis machining centres, increasing production capacity while maintaining dimensional consistency across all series and lot sizes.
In-House Production — From Billet to Finished Coupling
We maintain end-to-end manufacturing control across every step of the coupling production process, with no critical machining operations outsourced.
Vertical Integration for Consistent Dimensional Quality
Our facility combines multi-axis CNC turning centres, vertical machining centres, and a dedicated anodising line under one roof. This vertical integration means that every production step — from bar stock to finished black-anodised hub — is controlled by our engineering team against our own inspection standards, without reliance on subcontractors.
Incoming aluminium billet and polymer disc blanks are batch-verified against material certificates before entering production. Bore diameters are held to H7 tolerance as a default; tighter H6 bores are available for applications requiring minimal clearance fit, such as direct servo shaft connections. All bores are verified on CMM equipment against master gauges before release.
What We Bring to Every B2B Partnership
Our technical and commercial capabilities are built to support the full lifecycle of an OEM coupling supply relationship.
Application Engineering Support
Our engineers review your drive data — torque, speed, bore sizes, and operating environment — and recommend the correct series, disc material, and hub fixation method. If your application is at a series boundary, we will tell you clearly and propose alternatives.
Custom Bore and Keyway Machining
Standard metric and inch bores are held in stock configurations. Non-standard bore diameters, keyway profiles, set-screw patterns, and counterbores are machined to customer drawings. We require a 2D or 3D dimensional specification for custom work.
3D CAD and Documentation Package
STEP format 3D models and 2D dimensional drawings are provided for all standard products and custom configurations. Material certificates, CMM inspection reports, and ISO certificates are supplied on request as standard for OEM customers.
OEM and Private Label Programmes
We supply grey-label couplings to distributors and system integrators. Custom packaging design, part numbering schemes, and label printing are part of our standard private-label offering for qualified volume buyers.
Blanket Order and Stock Management
For distributors and machine OEMs with repeating demand, we operate framework blanket orders with scheduled release quantities. This allows customers to guarantee pricing and availability without carrying excessive inventory capital.
Export and Incoterms Compliance
We ship under EXW, FOB, and CIF Incoterms and accept T/T and L/C payment. Our export documentation includes commercial invoice, packing list, certificate of origin, and material certificates formatted for customs clearance in major import markets.
ISO 9001:2015 — Quality Built Into Every Stage
Our ISO 9001:2015 certified quality management system is not a document filed in a cabinet. It is the operational framework through which every production batch is planned, executed, inspected, and recorded. The system covers four critical stages:
-
Incoming Inspection: aluminium billet, polymer disc blanks, and fasteners are batch-tested against material certificates and dimensional standards before entering production stock.
-
In-Process Verification: bore diameters and tongue geometry are checked at machining stage against master gauges. Any non-conforming parts are quarantined before they reach subsequent operations.
-
Final Outgoing Inspection: finished coupling assemblies are measured on CMM for bore diameter, concentricity, face runout, and overall length. Batch inspection records are retained for traceability.
-
Continuous Improvement: non-conformance events feed directly into our corrective action process. Dimensional trends are tracked across batches to detect and address tool wear or process drift before they become customer-facing issues.
ISO 9001:2015
Current certification covering all manufacturing, inspection, and supply processes at our facility.
CMM Inspection
Coordinate measuring machine verification on bore diameter, runout, and geometry for every batch.
Material Traceability

Our European customer base spans the United Kingdom, Germany, France, Italy, and the Nordic countries. CE documentation and metric DIN-compatible bore specifications are standard on our European supply configurations.
Australia and New Zealand
We have served the Australian and New Zealand industrial machinery market for over a decade, with CIF shipping to major ports and familiarity with Australian standards for mechanical components.
South Korea and Japan
Precision standards in Korean and Japanese manufacturing are among the most demanding globally. Our H6 bore tolerance option and tight surface finish specifications were developed largely in response to requirements from customers in these markets.
Middle East
We supply food packaging and industrial automation customers across the UAE, Saudi Arabia, and surrounding markets, with Arabic-language documentation available for customs and procurement requirements on request.
Southeast Asia
With proximity advantage and growing automation investment in the region, we serve machine tool builders and distribution partners across Singapore, Malaysia, Thailand, Vietnam, and Indonesia.
The Principles Behind Everything We Build
Four convictions have guided our decisions since the company was founded, and they remain unchanged today.
Engineering Integrity
We design and manufacture to the specification, not to the appearance of it. If a tolerance cannot be held, we say so before production, not after.
Partnership Mindset
We treat every B2B customer as a long-term supply partner. Short-term pricing wins that compromise quality or erode trust are not how we operate.
Continuous Improvement
Every non-conformance is a data point for improvement. We invest in measurement capability, process documentation, and operator training year on year.
Transparent Communication
We give clear, technically grounded responses to enquiries. If a product is not right for an application, we say so and recommend what is.
Engineering-Led, Commercially Responsive
Our organisation is structured around engineering competence. The application engineering team handles all technical pre-sales and post-sales support — customers speak directly with engineers who understand rotational dynamics, tolerance chains, and material tribology, not with commercial intermediaries reading from a prepared brief.
Production is managed by experienced machining supervisors who have worked with our CNC equipment and inspection methods for many years. Consistency of personnel is one of the less visible but most important contributors to our lot-to-lot dimensional consistency.
Our export sales team is experienced in the documentation, Incoterms, and communication norms of our key markets in North America, Europe, and Asia-Pacific. We correspond in English as a standard and can accommodate Japanese and Korean language exchanges for technical queries in those markets.
