Built for Continuous Heavy-Duty Service

Our mill gearboxes and drive shafts are not repurposed general-purpose equipment. They are specifically designed for the extreme torque, shock loads, thermal cycling, and 24/7 continuous operation that define steel mill, mining, and cement grinding environments. Every component — from gear tooth profile to bearing selection to housing rigidity — is optimized for mill-specific operating conditions.

Full Process Control — Design Through Delivery

We own every step: engineering design, raw material procurement, casting, forging, CNC machining, heat treatment, assembly, testing, and export logistics. This vertical integration eliminates quality gaps between subcontractors, shortens lead times, and gives us direct control over every specification — no outsourced compromises.

Proven Project Experience Across Industries

Over two decades of delivered projects in steel rolling lines, mining ball mills, cement grinding circuits, sugar mills, and paper machine drives. Our engineering team understands the real-world operating conditions — not just from datasheets, but from years of field feedback, commissioning, and post-installation performance monitoring.

Globally Competitive Pricing

As a large-scale manufacturer — not a trading company — we offer factory-direct pricing without intermediary markups. Our cost structure benefits from in-house production of gears, shafts, housings, and forgings. You receive heavy-duty equipment that meets European quality standards at a price point that makes capital projects economically viable.

Fast Delivery from Rotterdam

Standard heavy-duty gearboxes ship in 30–45 days. Custom units in 45–90 days. Located at the Port of Rotterdam — Europe's largest — we have direct access to global shipping lanes. Buffer stock of key components and flexible shift scheduling allow us to respond to urgent orders without derailing existing production commitments.

Complete After-Sales & Spare Parts Support

Our relationship does not end at the dock. We provide 18-month product warranty, remote diagnostic assistance, spare parts on expedited delivery, preventive maintenance programs, on-site commissioning, and operator training. When a critical mill drive goes down, our after-sales team responds — not a voicemail system.

Paper Industry — Northern Europe

Paper Machine Drive Train Modernization

Provided a complete set of precision speed reducers and flexible couplings for a Fourdrinier paper machine — covering wire section, press section, and dryer section drives. Low-backlash gear design (≤ 3 arcmin) ensured synchronization accuracy across all machine sections. The modernization eliminated chronic vibration issues in the press section and extended bearing replacement intervals from 12 months to over 36 months.

Scope: Speed Reducers + Couplings + Alignment Service

"We replaced our rolling mill main drive gearboxes with EVER POWER units during our annual shutdown. The dimensional compatibility was exact — no foundation modifications required. The gearboxes have been running for over 18 months now with zero unscheduled downtime. Vibration levels are well below our acceptance criteria. We have since ordered spare gearsets for our backup inventory."

V. Krishnamurthy

Maintenance Manager — Steel Rolling Mill, India

"Our ball mill gearbox supplier went out of business and we needed replacement units quickly. EVER POWER reverse-engineered our existing gearbox from dimensional surveys, manufactured two new units in 52 days, and shipped them CIF to our port. The quality of the gears and machining exceeded our expectations. Their engineering team was responsive and professional throughout the process."

C. Mendoza

Plant Engineering Director — Copper Mine, Chile

"We have been sourcing industrial speed reducers and universal drive shafts from EVER POWER for four years now. The pricing is significantly more competitive than European OEM brands, but the quality — particularly the gear accuracy and surface finish — is comparable. Their after-sales support has been reliable. We consider them a strategic supplier for our mill equipment division."

M. Al-Rashidi

Procurement Head — Industrial Equipment Group, UAE

"What impressed me most was their willingness to customize. We needed a non-standard mounting configuration for our paper machine dryer section drive. Most suppliers quoted 4–5 months. EVER POWER delivered a fully tested unit in 60 days with complete documentation including FEA reports and GA drawings. The gearbox has been running smoothly for over a year."

J. Lindqvist

Technical Manager — Pulp & Paper Mill, Sweden

"We evaluated three suppliers for our cement vertical roller mill gearbox replacement. EVER POWER won on a combination of technical capability, price, and lead time. The factory acceptance test was thorough — we witnessed a 72-hour full-load run with temperature and vibration monitoring. The commissioning engineer they sent to our site was knowledgeable and efficient. Very satisfied."
