COMPLETE GEARBOX SOLUTIONS. EVERY SPECIFICATION. ONE SOURCE.

Industrial gearboxes and power transmission assemblies are the mechanical heart of every production line. In textile plants, glass factories, food processing, mining, construction, and packaging industries — the failure of a single gearbox reducer or a worn gear set can halt an entire operation for days, costing far more in downtime than the part itself.

At InStock International, we supply the complete range of industrial gearbox reducers and power transmission components — whether you need a standard unit by frame size, a custom-specified gearbox by input/output torque and reduction ratio, or an OEM-equivalent replacement for an existing installed unit.

Tell us your input speed, output speed, torque requirement, mounting configuration, and shaft dimensions — and we will source or manufacture exactly what you need. No catalogue browsing. No guessing. Direct technical matching.

What We Support

We deliver comprehensive gearbox and power transmission solutions for industrial buyers — from standard off-the-shelf reducers to fully custom-specified assemblies.

Complete Gearbox Reducers

Full range of industrial gearbox reducers for continuous-duty applications — Cycloidal, Helical Bevel (K-Series), Parallel Shaft Helical (F-Series), Worm, Planetary, and Helical Worm (S-Series) configurations. Available by frame size or custom-specified by input/output parameters.

Custom-Spec Supply to Your Requirements

You don't need a catalogue number. Share your input RPM, output RPM, torque requirement, mounting type, shaft dimensions, and application details — we configure and source the exact gearbox for your installation. Suitable for new machine builds, line upgrades, and direct replacements.

Gearbox Spare Parts & Repair Components

Comprehensive spare parts supply for installed gearbox fleets — including eccentric bearings, gear plates, bearing kits, seal kits, O-ring sets, worm wheels, worm shafts, pinion assemblies, and precision-machined housings. No need to replace the full unit when a spare part can restore full performance.

Ongoing Supply & Technical Support

We support industrial buyers with scheduled spare parts supply, technical guidance on gearbox selection and replacement, and long-term supply agreements for repeat orders. Whether you manage a fleet of 10 or 500 gearbox units — we provide the supply consistency your operation depends on.

Where We Add Value

Our technical depth and flexible sourcing approach deliver gearbox solutions that fit your exact application — not the closest available standard.

Specification Matching

Every gearbox supplied is matched to your actual operating requirements — input/output speed, torque, service factor, mounting configuration, and operating environment. We don't recommend the nearest available; we source the right one.

Multi-Type Coverage

From cycloidal units for high-precision, low-backlash applications to heavy-duty helical bevel reducers for high-torque industrial drives — we cover every gearbox type relevant to industrial production environments.

Reverse Engineering & Localisation

For obsolete or discontinued gearbox models — share your existing unit, drawing, or worn components. We reconstruct the geometry, identify the correct material specification, and produce a locally manufactured equivalent at a fraction of the import cost.

Export-Ready Standards

All gearbox units and spare components are supplied with full technical documentation — dimension sheets, material certificates, and quality verification aligned with international industrial procurement standards.
