Are you building your own generator or modifying an exercise bike for power generation? The right friction contact point makes all the difference between efficient energy conversion and frustrating mechanical failure. This high-quality rubber drive roller is engineered specifically for DIY enthusiasts who need reliable, consistent friction to transfer mechanical motion into electrical power.
Manufactured from premium polyurethane with a 70A hardness rating (D2240), this friction roller strikes the perfect balance between grip and flexibility. The material specification shows excellent properties: 439 psi at 100% modulus, 675 psi at 200% modulus, and 1130 psi at 300% modulus, ensuring it maintains its shape under pressure while providing consistent contact. With an ultimate tensile strength of 5,454 psi and 429% elongation, this roller can handle the repetitive stress of continuous use without cracking or degrading.
The 1.5-inch diameter roller with 0.75-inch width creates an optimal contact surface area for maximum friction without excessive wear. The stainless steel 8mm hub provides corrosion resistance and precise shaft mounting, ensuring smooth rotation and minimal vibration. Whether you're connecting it to a generator shaft, motor spindle, or exercise bike dynamo, this roller delivers the reliable contact you need for efficient power conversion.
This friction roller excels in multiple DIY scenarios:
The low compression set (4% after 22 hours at 158°F) means it maintains its shape over time, ensuring consistent performance. If you're serious about renewable energy projects or mechanical power generation, this friction roller provides the reliability and durability you need to keep your projects running smoothly for years to come.
