The 25 mm Bearing Carrier – Baby Kart – Scout model is made of anodized aluminum, designed to house 25 mm inner diameter bearings on children's kart axles. The bolt spacing is 67 mm, a standard measurement for many baby kart chassis.

This component is compatible with Baby Kart chassis, such as the Scout line, which use 25 mm axles. It's important to verify compatibility with your specific chassis before purchasing.
