"How much does a planetary gearbox cost?" is one of the most common questions procurement teams and plant engineers ask — and the honest answer is that it depends on several factors. A small precision planetary gearbox and a large high-torque industrial unit can differ in price by a factor of a hundred or more.
There is no single "planetary gearbox price list" that fits all needs, because these gearboxes are engineered to a specific torque, ratio and mounting requirement. This guide explains every factor that determines planetary gearbox price, gives indicative ranges for budgeting, and shows exactly what to share to get an accurate quote from Kavitsu Transmissions.
6 Factors That Determine Planetary Gearbox Price
1. Output Torque
Torque is the single biggest driver of price. A gearbox rated for higher output torque needs larger gears, stronger shafts, bigger bearings and a heavier housing — all requiring more material and machining. Kavitsu manufactures from 100 Nm up to 250 kNm; a unit at the top of that range costs dramatically more than one at the bottom, simply due to size and mass.
2. Gear Ratio & Number of Stages
A single-stage planetary gearbox (ratio 3:1 to 10:1) is the most economical. Higher ratios require two or three stages — each additional stage adds a full planetary gear set, more components and more assembly labour. A three-stage high-ratio gearbox costs significantly more than a single-stage unit of the same torque class.
3. Mounting Configuration
Inline (coaxial) planetary gearboxes are the base configuration. Right-angle output (bevel-planetary) adds a bevel gear set and additional machining, increasing cost. Flange mount, foot mount and shaft-mount variations also affect the housing design and price. The more complex the output arrangement, the higher the cost.
4. Precision & Backlash Requirement
Standard industrial gearboxes (backlash under 8 arcmin) are cost-effective. Precision units (under 3 arcmin) and zero-backlash gearboxes for robotics and automation require tighter machining tolerances, better gear grades and more careful assembly — commanding a premium over standard units.
5. Protection Class & Special Requirements
Standard IP55 protection is included; IP65 sealing for dusty or wet environments adds cost. Special requirements — high-temperature operation, food-grade lubricants, special coatings, or custom shaft/flange designs — all add to the base price.
6. Quantity
A single prototype or one-off unit carries the full setup, programming and tooling cost on one piece. Series orders spread these fixed costs across multiple units, lowering the unit price. For OEMs with regular requirements, blanket orders and frame agreements deliver the best pricing.
Why Buying Direct from the Manufacturer Saves Money
Kavitsu Transmissions is a direct planetary gearbox manufacturer — not a trader or distributor. Buying direct means no middleman margin, faster delivery, direct access to the engineering team, and better pricing than buying through a dealer. For imported-brand replacements, an Indian-manufactured equivalent from Kavitsu is typically far more economical than the original imported unit while matching the specification.
Planetary Gearbox Specifications That Affect Price
| Parameter | Range (affects price) |
|---|---|
| Output Torque | 100 Nm to 250 kNm |
| Gear Ratio | 3:1 (single stage) to 1000:1+ (multi-stage) |
| Number of Stages | 1, 2 or 3 stages |
| Mounting | Inline / Right-angle / Flange / Foot / Shaft-mount |
| Backlash | <8 arcmin standard / <3 arcmin precision / zero-backlash |
| Protection Class | IP55 standard / IP65 on request |
| Efficiency | Up to 97–98% per stage |
Tip for procurement teams: Always request a quote that breaks out the unit price, packing and freight separately — this gives you the true landed cost for accurate comparison across suppliers.
