Order Robot Clutches & Gears Online - Fast Local Stock for Makers and Engineers

Get the right clutch and gear parts for your robot - now

Designing or repairing a robot should not stall because a crucial clutch, gearbox or gearset is out of reach. At Communica we keep a broad selection of robot clutches, planetary and spur gears, gearboxes and accessory kits available locally so South African makers, students and engineering teams can continue building with minimal delay. Order robot clutches gears online and choose branch collection, fast delivery or account quoting for procurement buys.

Why order from local stock

Local availability reduces lead time and gives you VAT-compliant invoices for school or departmental purchases. You can check stock in Samrand or collect from our Pretoria and Cape Town branches, or use our sub-distributor network for wider reach.

Common robot clutch and gear options

• Electromagnetic clutches for simple engage/disengage control
• Mechanical friction clutches for adjustable slip torque
• Planetary gearboxes for compact, high torque output
• Spur and helical gears for drivetrain and transmission tasks

Quick spec callouts when ordering robot clutches gears online

When you review parts, focus on rated torque, input speed (RPM), mounting dimensions and shaft compatibility. If you need help selecting, compare specifications on our brand pages: Shop by Brand. For a rapid parts browse of everything we stock, see our complete index: All Products.

Basic torque and gear ratio formulas

Use these quick formulas to verify part suitability: Torque load = Force × Radius. Gear ratio = driven teeth / driving teeth. Output torque = input torque × gear ratio (minus efficiency losses).

Example: a 10 Nm motor through a 5:1 gearbox gives roughly 50 Nm at the output before accounting for gearbox efficiency (typically 80-95% depending on design).

Wiring/installation sketch

Motor -----[coupling]----- input shaft
               |
               +-- clutch -- output shaft --> gearbox --> wheel

Clutch control: MCU GPIO --> Driver --> Clutch coil (with flyback diode)

For electrical clutches ensure proper driver current rating and a diode when driving inductive loads. For mechanical clutches, check mounting and axial clearance.

Choose confidently - bundles, compatibility notes and procurement options

We design our offering to suit student projects, maker builds and industrial prototyping. Look for bundled options that group a motor, gearbox and clutch with compatible couplings and mounting plates to reduce engineering time. If you need a quote for department procurement, request an account quote and we will prepare a VAT invoice and lead-time details for bulk buys.

Compatibility guidance and common pairings

Match shaft diameters, keyway dimensions and mounting bolt patterns. Popular pairings stocked locally include small DC motors with 5:1 and 10:1 planetary gearboxes for mobile robots, and electromagnetic clutches paired with stepper motor drives for precise engage/disengage control. If a specific item isn’t shown in your branch, check stock and branch pickup details: Branches & Trading Hours.

Accessory recommendations

• Precision couplings and flexible shafts to reduce misalignment stress
• Mounting plates and adapter flanges matching gearbox footprints
• Motor drivers and clutch drivers with appropriate current margins
• Spare gear sets and lubricant for high-load applications

Handling objections - lead times, fitment and returns

Concerned about lead times? We prioritise local stock for fast collection from Samrand or branches; when an item is a special order we provide realistic lead-time estimates and procurement support. Unsure about fitment? Use our spec tables and ask our technical team for compatibility checks - we can suggest compatible parts and bundles from our catalogue: Communica homepage. For education customers, VAT invoices and account support are available for institutional purchases.
