About EVER POWER
Built on Precision.
Backed by Scale.
EVER POWER is a specialist manufacturer of planetary gear sets, gear stages, and drivetrain components, with design and manufacturing operations in Hangzhou, China, and a European trading presence in Rotterdam, Netherlands. We deliver precision-engineered gearing to demanding industrial applications across the globe.
Company Overview
Who We Are
EVER POWER is a manufacturer's brand under the Ever Power Group — a Hangzhou-based industrial drivetrain group with more than two decades of engineering and manufacturing history in power transmission products. The group supplies gearboxes, couplings, chains, sprockets, and related drivetrain components to industrial customers across Europe, North America, Southeast Asia, and the Middle East.
The planetary-gear-set.top operation is run by EVER POWER's European entity, based in Rotterdam, Netherlands, which handles customer enquiries, sales coordination, export documentation, and logistics for European and global orders. The Rotterdam office operates as a marketing agency and overseas branch of the group; all manufacturing is performed at the group's Hangzhou facilities.
Our approach is direct: experienced technical staff, factory-controlled production, and transparent documentation. We do not broker through intermediaries. When you source from EVER POWER, your supply chain connects directly to the manufacturing facility where your components are produced.
We serve a wide range of end-user applications, from agricultural and construction equipment to industrial gearbox rebuilds, automation systems, and specialist vehicle drivetrains. Whether your requirement is a standard catalogue gear stage or a precision custom assembly, our team provides the technical depth and production capacity to fulfil it reliably.
Production & Facilities
Manufacturing Capability
Our Hangzhou facilities combine precision machining, heat treatment, and rigorous in-process inspection — giving us full control over component quality from raw material receipt to finished-gear dispatch.
Gear Cutting & Grinding
CNC hobbing and grinding machines for external, internal, and helical gear teeth. Surface finish and profile accuracy held to DIN 6 – DIN 8 grade as standard, with tighter tolerances available.
Heat Treatment
In-house carburising, case hardening, and induction hardening lines with controlled atmosphere furnaces. Hardness depth profiles provided on request for critical applications.
Precision Turning & Milling
Multi-axis CNC turning centres and machining centres handle shafts, carriers, ring gears, and housings to tight positional and dimensional tolerances.
CMM & Metrology
Coordinate measuring machines, gear testers, and surface profilometers used throughout production. Full dimensional inspection reports available per batch.
Assembly & Testing
Planetary gear stages and multi-stage gearboxes assembled in a controlled environment, run-tested under load, and sealed before packing. No-load and full-load test options available.
Material Control
20CrMnTi, 42CrMo, and 40Cr alloy steels sourced from certified mills. Incoming material subject to hardness, composition, and ultrasonic checks prior to production release.

| Mounting Type | Flange, foot, hollow bore | Custom adapter plates |
What We Make
Product Scope
Our planetary gear product range covers both catalogue and custom-engineered designs across a broad torque and ratio spectrum.
Inline Planetary Gearboxes
Single and multi-stage configurations for servo motors, hydraulic motors, and electric drives. Compact, high-efficiency units with standard IEC or NEMA flange interfaces.
Right-Angle Planetary Gearboxes
Integrated bevel-planetary designs for applications where shaft orientation must change. Available with hollow and solid output shafts.
Slewing Drive & Ring Gear Assemblies
Planetary slewing drives for solar trackers, cranes, aerial platforms, and construction equipment. Internal and external ring gear options.
Wheel Drive & Travel Drive Units
Final drive planetary units for compact excavators, skid steers, forklifts, and agricultural equipment. Disc brake and parking brake variants available.
Winch & Hoist Planetary Gears
High-ratio planetary reduction stages for cable winches, anchor winches, and industrial hoists. Built for cyclic high-load operation.
Individual Gear Stage Components
Sun gears, planet gears, ring gears, and carrier assemblies supplied individually for gearbox rebuild, OEM production, and aftermarket replacement.
Quality Assurance
Quality & Third-Party Verification
We support transparent sourcing. Our manufacturing operation has undergone independent supplier audit and company verification, providing buyers with documented confirmation of our identity and production capabilities.
SGS / TÜV Rheinland
Supplier Verification
We have completed third-party supplier audit and company verification supported by SGS / TÜV Rheinland. This verification helps buyers review company identity, business operations, supplier profile, and general manufacturing capability. Product-specific inspection reports, material documents, or compliance records can be provided according to order requirements.
- ISO 9001 quality management system governing all production processes
- In-process inspection at gear cutting, heat treatment, and final assembly stages
- Full dimensional inspection and gear-accuracy measurement per production batch
- Material traceability from certified steel mill to finished component
- Load testing and no-load run-in testing available for assembled gearboxes
