9mm ringless machined aluminum rollers M4WD-29/RE, red finish

These 9mm ringless ball race rollers feature a machined aluminum body and are supplied as individual spare rollers for Mini 4WD use. The ball-type contact surface is matched to common 9mm roller setups, while the red anodized finish distinguishes this variant for display and repair purposes.

Practical note for builders: removing the outer ring reduces the roller contact diameter, which can be beneficial where chassis clearance is tight. Verify roller post straightness and spacer configuration before locking the roller in place to keep predictable contact with guide walls.

Material and finish details are limited to the manufacturer description: machined aluminum construction, red anodized treatment, and a ball-style running surface. Use standard Mini 4WD assembly techniques and confirm free rotation after installation to prevent drag from nearby parts.

Do these fit standard 9mm roller setups out of the box?

They are intended for standard 9mm arrangements, but double-check your post diameter, any spacer flange and clearance to ensure proper fit and rotation.

Will the red anodize wear quickly?

Anodize is a surface finish and will show wear over time where frequent rubbing occurs; consider protective measures if you expect heavy contact.

Is the ball contact surface noisy?

Aluminum ball-contact rollers are normally quiet in passive service; if you hear noise, inspect mounting and consider a light drop of oil at the axle interface.

Are these sold individually or as a set?

The product is supplied as individual rollers. Compatibility will depend on your existing axle, bushing and spacer layout.
