Consolidated Precision Bearings STO-15 Ball Bearing

Consolidated Precision Bearings STO-15 Ball Bearing is a compact radial bearing designed for smooth, low-friction rotation of shafts in precision machinery. It features a 15 mm bore, 35 mm outer diameter, and 12 mm width, delivering a small, rigid package suitable for tight spaces. This STO-15 model is used wherever accurate shaft support and repeatable motion are required, from automated assemblies and robotics to precision tooling and small machine tools. With precision-engineered raceways and balls, the bearing supports radial loads with consistent performance and helps maintain alignment during operation. The exact bore, outer diameter, and width provide clear fitment specifications for housings and shafts, enabling straightforward geometry-based selection in design or retrofit projects. When selecting this bearing, verify that your shaft and housing accommodations meet the 15 mm bore, 35 mm outer diameter, and 12 mm width to ensure proper clearance and seating. Compact and versatile, it adapts to a range of small-scale systems where reliable operation counts, and is commonly paired with standard shafting and bearing housings that accept a 15 mm bore.
