collaborated with a baby travel brand to customize silent hardware wheel sets for baby walkers. Using high-speed silent bearings with ABS anti-slip wheel surfaces, the rotation resistance is reduced by 40%, and there is no noise when driving to avoid disturbing the baby. The wheel axle is precision machined with 45# steel, and the reinforced design eliminates the hidden danger of rollover, with a load-bearing capacity of 30kg, suitable for different ground materials. The surface is treated with environmentally friendly spraying, odorless and free of harmful substances, meeting baby safety standards. This customized wheel set helped the partner increase walker sales by 55% year-on-year, becoming the preferred supporting product for mothers’ baby walker equipment.
