The Shimano Steel Ball 1/4" x 18 #000 9131 is a high-quality replacement ball bearing set designed for smooth and reliable wheel performance. These precision steel balls are commonly used in traditional cup-and-cone hubs, where durability and consistent rolling are essential. Manufactured to Shimano’s exacting standards, they help restore worn hub bearings, reduce friction, and improve the overall feel of your wheels. Whether you are servicing an older wheelset or performing routine maintenance on a frequently used bike, fresh steel balls are a simple and cost-effective way to extend hub life.
Ideal for home mechanics and professional workshops alike, these 1/4" steel balls are suitable for many front and rear hub applications that use loose bearings. Replacing tired or pitted balls can eliminate roughness, play, and unwanted noise, helping your wheels spin more freely and predictably. Pair them with quality grease and properly adjusted cones for a smooth, long-lasting bearing setup. Compact and easy to store in any toolbox, this Shimano steel ball set is a small but essential component for keeping your bike rolling efficiently and confidently on every ride.
