Order Robot Wheels Online - Fast Local Stock for Makers & Engineers

Get the right wheels for your robot - fast

When a prototype or student project deadline is looming, dependable local availability matters more than a long product description. Communica offers a practical range of robot wheels, gearwheels, omni wheels, caster assemblies and complete wheel kits designed for hobbyists, tertiary labs, technicians and procurement teams across South Africa. Benefit from locally held stock, branch collection and VAT-compliant invoices so you can move from idea to testing without import delays.

Why order robot wheels from Communica?

• Rapid availability from Samrand, Pretoria CBD and Cape Town branches with branch collection options - check our locations here.
• Range depth: silicone tyres, rubber tread, lightweight plastic rims, hub-mounted gear wheels and omni/Mecanum wheels for holonomic drive systems.
• Support for students and labs: buy single wheels or full kits suitable for classroom builds and prototyping runs.

Quick spec callouts

When selecting wheels, consider diameter, tread material, hub bore, load capacity and whether you need a geared or direct-drive option. For small mobile robots a 65-100 mm diameter wheel is common; larger inspection robots often use 150 mm and above. Hub bore size must match your motor shaft or wheel hub adapter - common shafts include 3mm, 4mm, 6mm and 8mm.

Compatibility and accessory guidance

Confirm shaft diameter and mounting pattern before ordering. Where the wheel hub does not match your motor, use hub adapters, grub screws or shaft collars. Communica stocks adapters, set screws and motor brackets in our tools and enclosures collections - browse relevant categories robot wheels stockist and all available parts here.

Specification checklist before you buy

• Wheel diameter and width
• Hub bore and mounting method (grub screw, D-shaft, keyed)
• Tread material for your surface
• Load per wheel and robot total weight
• Compatibility with encoders or slip rings if used

Simple load calculation example

Estimate wheel load: divide robot weight by number of wheels and add safety margin (typically 25%). Example: a 6 kg rover on four wheels: 6 kg / 4 = 1.5 kg per wheel; add 25% = 1.9 kg. Choose wheels rated above that per-wheel load.

Compatibility, wiring notes and practical build tips

Wiring and motor control for wheel-driven robots is straightforward but often overlooked during parts ordering. Ensure motor controllers support your motor voltage and current; add motor drivers and fuses when needed. For encoders, make sure the wheel hub or adapter allows encoder mounting or pick wheels with pre-machined encoder slots. For a quick primer and brand options, visit our Shop by Brand page here.

Troubleshooting common wheel issues

• Wheel slip on smooth floors: choose softer rubber tread or increase wheel diameter.
• Misaligned hubs: use keyed shafts or set-screw hubs for positive drive.
• Noise/vibration: balance the wheel or switch to a softer compound.

Local availability, lead times and support

We keep many popular wheel types in stock at our Samrand head office/warehouse for fast collection - check stock and branch pickup options on our homepage here. For larger orders or classroom kits, request a quote for volume pricing and VAT invoices by contacting sales - accounts and procurement can request formal quotes and delivery lead times. If an item is out of stock, Communica can advise on nearest alternatives and typical lead times based on supplier availability.

Accessory bundles and compatibility callouts

We recommend ordering matching hub adapters, shaft collars and mounting hardware with wheels to avoid downtime. Consider pre-made wheel kits that include wheels, motors and brackets for fast builds. When in doubt, use our product category pages to compare sizes and specs here.
