Overview
This high-precision steel ball bearing is engineered specifically for light-duty industrial machinery and motor assemblies requiring reliable rotational support in compact spaces. With a bore diameter of 0.31 inches and an outside diameter of 0.75 inches, the unit offers a space-saving design without compromising on structural integrity or load capacity. The bearing width measures 0.24 inches, allowing for seamless integration into tight mechanical configurations. Constructed from high-grade steel, this component delivers exceptional durability and resistance to wear under continuous operation. Each unit features double metal shields that effectively retain internal lubrication while preventing the ingress of dust, debris, and other environmental contaminants. The C3 internal clearance specification is critical for applications involving elevated operating temperatures or high rotational speeds, as it accommodates thermal expansion and minor shaft misalignment to prevent premature failure. Supplied in bulk industrial packaging with a package quantity of 50 units, this solution is ideal for maintenance teams and original equipment manufacturers seeking consistent performance and extended service life across multiple installations.
Key Features
Double metal shield design for superior contaminant exclusion and lubrication retention C3 internal clearance optimized for high-speed rotation and thermal expansion compensation High-grade steel construction ensures maximum durability and wear resistance Compact profile with 0.24-inch width suitable for space-constrained applications Precision ground races provide smooth operation and reduced friction Bulk pack of 50 units supports large-scale maintenance and production needs
