The raw flywheels are completed with a grinding process and then sent for the final finishing step. We maintain a tight tolerance range for the flywheel size, with a minimum of +0.00 and a maximum of +0.05. Our flywheel range for machining starts from 36OD (Inches) up to 55OD (Inches) with all complete operations including keyway. We take great care in ensuring that our flywheels meet high standards of quality and precision. The combination of the grinding process and our strict tolerance standards helps us to produce flywheels that are durable, reliable, and efficient.
