Description
Silicone Straight Stretch Core Flex Wheels for Robotics & Mechanisms
The Straight Stretch Core Flex Wheels are high-performance flexible traction wheels designed for use in robotics mechanisms, intake systems, conveyor systems, and shooter drives where reliable grip and compliance are critical.
Made from a custom high-strength silicone rubber compound, these flex wheels offer excellent traction, durability, and controlled compliance compared to conventional wheels. They come in multiple diameters and durometers (hardness ratings), allowing you to match wheel stiffness to your specific application—from soft grip to medium or firm traction.

Variants – Diameter & Durometer Options
| Variant | Outer Diameter (OD) | Width | Bore / Mount Type | Durometer (Hardness) |
|---|---|---|---|---|
| Straight Flex Wheel – 1.625″ | 1.625″ (≈41mm) | ½″ wide | Stretch over ½″ hex shaft | 30A / 45A / 60A |
| Straight Flex Wheel – 2″ | 2″ (≈50mm) | ½″ wide | Stretch over ½″ hex shaft | 30A / 45A / 60A |
| Straight Flex Wheel – 3″ | 3″ (≈76mm) | 1″ wide | Stretch over 1″ hub or roller | 30A / 45A / 60A |
| Straight Flex Wheel – 4″ | 4″ (≈100mm) | 1″ wide | Stretch over 1″ hub or roller | 30A / 45A / 60A |
Durometer Notes:
• 30A – Soft, high compliance grip
• 45A – Medium hardness (balanced traction)
• 60A – Harder wheel (firmer roll, less deformation)
