What to Include for a Same-Day Response

Enquiries with these five data points receive a confirmed recommendation within hours. Without them, we need to ask follow-up questions — which delays your answer.

Required Torque

Output torque in N·m or kg·m. Include service factor if known (shock load = 1.5×–2×)

🔄
Output Speed

RPM at the output shaft. Or give motor speed + desired ratio if known

💧
Environment

Dry / humid / outdoor / washdown / chemical exposure. IP rating requirement if known

🔌
Motor Power & Frame

Motor kW and IEC frame code (e.g. 71B14). Or "servo — shaft coupling input" for VRV

📦
Quantity & Timeline

Units needed, delivery country, and urgency. Sample order or production run?

Optional but helpful: Application industry, existing reducer brand/model you're replacing, shaft configuration (horizontal/vertical/inverted), cycle frequency (continuous / intermittent), ambient temperature range.

Our Process

What Happens After You Send Your Requirements

A transparent process — so you know exactly what to expect from the moment your enquiry lands in our inbox.

1
Enquiry Review — within 2 hours

Our engineering team reads your specification against our range. If information is missing, we send one focused follow-up question — not a generic form to fill in.

2
Series & Ratio Confirmation — within 24 hours

We confirm the recommended series, frame size, ratio, and motor code. We include Fr2 and Mn2 data for the selected ratio, and flag any thermal or mounting considerations for your application.

3
Price & Lead Time — same day

Unit price (ex-works Korea), available stock, lead time for production quantities, and Incoterms options. No obligation. No follow-up sales calls unless you request them.

4
Sample & Documentation — on request

Sample units available for qualification testing. Full dimensional drawings, ISO certificates, bearing brand documentation, and test reports available at no extra cost for orders over MOQ.

Buyer FAQ

Common Questions from New Customers

The five questions we answer most often from engineers and procurement teams making their first order with Korea Ever-Power.

Do you accept orders without a minimum quantity? +
Yes. We accept single-unit sample orders for qualification testing. For production quantities, MOQ varies by series and frame size — typically 5 units for standard configurations, 50+ for OEM custom specifications. Contact us with your quantity and we'll confirm pricing at both sample and production volume.
What is the shipping lead time to Korea, Japan, and Southeast Asia? +
Stock items typically ship within 5–7 business days from our Ansan-si, Gyeonggi-do facility. Transit to Korea domestic: 1–2 days. Japan and Taiwan: 3–5 days sea freight, 1–2 days air. Southeast Asia: 5–10 days sea. Non-standard ratios or OEM custom specifications: 3–6 weeks production lead time. Provide your required delivery date in your enquiry and we'll advise the most appropriate shipping mode.
Can I get dimensional drawings before placing an order? +
Yes — free of charge. Request by email with the series and frame size. We supply 2D outline drawings (DWG or PDF) and where available, 3D STEP files. For VRV030 precision series replacing an Ondrives & Rino P-series unit, we provide a dimensional comparison document showing fit confirmation. Please allow 1–2 business days for drawing delivery.
Do you supply ISO 9001 and material certification documents? +
Yes. Our ISO 9001:2015 certificate is available on request. For OEM builds requiring ATEX certification dossiers or customer quality records, we provide: ISO 9001 certificate copy, bearing brand documentation (NSK or SKF if specified), worm shaft material certificates (20CrMnTi with heat treatment report), and measured backlash values for precision VRV030 AR-class units. Specify your documentation requirements in the enquiry.
I'm replacing a competitor's unit. What information do you need to confirm dimensional compatibility? +
Send us the competitor's model number, series designation, and ratio. If available: centre distance, output shaft diameter, IEC flange code, and mounting position. For Ondrives & Rino P-series replacements (VRV030), we have dimensional comparison tables available immediately. For other competitor brands, we will confirm fit within one business day against our dimensional database, or request additional measurements if needed. We prefer to confirm compatibility before your first order rather than resolve a fitment issue after delivery.
