Overview
This miniature steel ball bearing is engineered for high-precision industrial applications where space constraints demand compact components without sacrificing performance. Featuring a 0.2-inch bore and a 0.55-inch outside diameter, this unit delivers exceptional rotational stability and load capacity in demanding environments. The component is constructed from high-grade steel to ensure structural integrity under stress, while the double-shielded design effectively retains lubrication and excludes dust, debris, and other contaminants. This protection mechanism significantly extends service life and reduces maintenance intervals, making it an ideal choice for high-speed machinery that requires reliable, long-term operation. Each industrial package contains 25 units, providing ample supply for production lines, equipment repairs, or original equipment manufacturer assembly processes.
Key Features
Double-shielded construction for superior contaminant exclusion High-grade steel material ensures maximum durability and load handling Precision-ground races provide smooth rotation with minimal friction Compact 0.2-inch width allows installation in tight spatial configurations Optimized for high-speed rotational applications up to 30,000 RPM Consistent performance across a wide temperature range from -40°F to 250°F Industrial bulk packaging of 25 units per set for cost-effective procurement
