Baby carriage bearings are key components used in children's commuting tools such as baby carriages and scooters. They mainly adopt deep groove ball bearings (such as 608ZZ, 608RS, etc.), which have precise structure, low noise, and high efficiency Baby carriage bearings are mainly micro deep groove ball bearings, with common models including 608ZZ (inner diameter 8mm, outer diameter 22mm, height 7mm), 608RS (with sealed structure), 6900ZZ (double convex structure), etc. Among them, the 608 series has become a standard configuration for the front, rear, and steering wheels of baby strollers and scooters due to its compact size and high rotational accuracy. Features Reduce friction: Rolling friction is achieved through ball rolling, which reduces energy loss by about 70% compared to traditional sliding friction and improves sliding smoothness; Durable and Silent: Made of carbon steel material and processed with precision technology, the bearing life can reach 5000-10000 kilometers; Strong adaptability: supports shaft diameter range of 1.2-12.7mm, can adapt to different sizes of wheel sets.
