Crown / Drive Wheels

Crown and Drive Wheels are essential components used in roller garage door motor systems, particularly in tubular motor setups. Here’s a breakdown of what they are and their function:

What Are Crown & Drive Wheels?

• Crown Wheel: This part fits onto the motor head and helps position the motor securely inside the barrel of the roller door. It often has a splined or keyed design to align with the motor shaft.
• Drive Wheel: This component connects to the motor and transfers rotational force (torque) from the motor to the barrel, causing the roller door curtain to wind up or down.

Together, these wheels ensure that the motor can effectively rotate the barrel, allowing the door to open and close smoothly.

• Compatibility: Different motor brands (e.g. Somfy, Gliderol, SWS, SeceuroGlide, Novoferm) use specific crown and drive wheel designs. Using the correct set ensures proper fit and function.
• Wear & Tear: Over time, these plastic or nylon components can wear out, causing slippage or misalignment. Replacing them restores reliable operation.
• Installation: They are typically easy to fit during motor replacement or servicing, but must be matched to the motor model and barrel size.
