Industrial Gearboxes for Every Drive Application
Industrial gearboxes are critical infrastructure — not consumables. Selecting the wrong gearbox type, ratio, or frame size for your application leads to premature failure, unscheduled downtime, and production losses. Selecting the right one, supplied with full technical documentation and backed by consistent spare parts availability, is the foundation of reliable operations.
InStock International supplies the complete range of industrial gearbox reducers and power transmission components — matched to your exact operating requirements. We support buyers across the Textile, Glass, Food & Beverage, Mining, Construction, and General Industrial sectors with:
- Standard gearbox supply by frame size and type
- Custom-specified gearboxes by input/output RPM, torque, and mounting configuration
- Spare parts for installed gearbox fleets — eccentric bearings, gear plates, seal kits, shafts, and housings
- Reverse-engineered or localised components for obsolete or discontinued gearbox models
Share your specification — and we will deliver the right unit, not the nearest available.
FREQUENTLY ASKED QUESTIONS
Clear answers to common questions about our gearbox supply, spare parts capability, and custom specification process.
Yes — input and output speed, combined with the driven torque requirement and application type, is sufficient to identify the correct gearbox. Share your motor specifications (kW, RPM) and the required output speed or torque, and our team will configure the correct gear ratio, frame size, and gearbox type for your application.
Yes. Share the gearbox make, model number, or frame size — or the specific component you need (bearing kit, seal kit, gear plate, shaft, housing). We supply spare parts for all major gearbox types including cycloidal, helical bevel, worm, and parallel shaft reducers. For obsolete or discontinued models, we can reverse-engineer and locally manufacture the required components.
Yes. This is a common requirement. If your existing gearbox model is discontinued or the OEM has long lead times — share the unit with us (or its technical data), and we will develop a functionally equivalent replacement. Our reverse engineering capability covers geometry reconstruction, material identification, and controlled technical replication.
There is no strict minimum order quantity. We supply from single components for urgent maintenance needs through to large scheduled production batches for fleet maintenance programmes. Pricing scales with quantity — contact us for a tailored quotation.
