For Electric wheelchair, with keyway

The MUNIU MN20-R9M is an advanced magnesium alloy rear wheel designed for electric wheelchairs and power mobility equipment where reducing wheel weight directly extends battery range and improves motor efficiency. Magnesium alloy is approximately 33% lighter than aluminum and 75% lighter than steel at equivalent strength, making it the optimal material choice for powered mobility wheels that must withstand motor torque loads while remaining as light as possible. The MN20-R9M features a die-cast magnesium alloy hub and a roll-formed magnesium alloy rim, bonded into a unified assembly that delivers exceptional strength-to-weight performance. The reduced rotational mass means less energy is required to accelerate and maintain speed, directly translating to longer range per battery charge — a tangible benefit for end users and a compelling selling point for electric wheelchair OEMs. The wheel is finished with a multi-layer protective coating system that prevents magnesium oxidation and provides a durable, attractive surface in matte silver-gray. Sealed cartridge bearings ensure smooth, quiet rotation and zero maintenance throughout the wheel's service life. MUNIU produces the MN20-R9M in our Chongqing, China factory with in-house die-casting and finishing capabilities. OEM customization includes hub motor mounting patterns, rim width specifications, color options, and private labeling. Factory-direct wholesale pricing for electric wheelchair manufacturers and mobility equipment brands.
