To estimate your shipment, use the Gearboxes Freight Class Calculator.
The Gearboxes Freight Class Examples use the current 13-tier density scale, effective July 19, 2025, and range from Class 50 to 65.
These are density-based estimates.

Gearboxes shipment comparison
Gearboxes are typically dense, but housings, shafts, couplings, guards, mounting feet, oil preparation, and crate size can change the finished cube and handling profile. Compact reducers often ship efficiently, while large industrial gear drives may need reinforced skids and no-top-load handling.
| Gearboxes shipment | Typical packaging | Density tendency | Stackability | Planning note |
|---|---|---|---|---|
| Compact speed reducers | Reinforced carton or small skid | Very high | Usually stackable | Immobilize shafts and protect seals, keys, and mounting faces. |
| Palletized gear drives | Bolted to a reinforced pallet or skid | Very high | Limited | Distribute concentrated weight and protect protruding shafts. |
| Large industrial gearbox | Heavy skid or full crate | High | Usually non-stackable | Confirm lifting points, oil preparation, and center of gravity. |
| Gearbox with motor or coupling | Integrated skid with blocked accessories | High | Limited | Secure guards, couplings, motors, and loose hardware separately. |
gearbox shipping options
The right service depends on gearbox size, packaging, stackability, and handling needs.
| Gearboxes shipment | Common shipping option |
|---|---|
| Boxed compact reducer on a pallet | Standard LTL |
| Palletized industrial gear drive | Heavy LTL |
| Crated gearbox with exposed shafts | Crated LTL |
| Oversized gearbox or integrated drive package | Specialized or dedicated service |
Large, irregular, non-stackable, unusually valuable, or specially handled gearbox shipments may need carrier review before booking.

Freight classes shown on this page are density-based estimates for shipment planning. Actual classification may also depend on value, handling requirements, liability, stowability, dimensions, and other commodity-specific factors.
