Overview
This miniature ball bearing is engineered for high-precision applications where space constraints and rotational accuracy are critical. Designed with a compact footprint, the unit features a 0.315-inch bore diameter and a 0.472-inch outside diameter, with a slim width of just 0.138 inches. Constructed entirely from durable steel, this component delivers exceptional load-bearing capacity and structural integrity within small-scale machinery. The design incorporates double metal shields on both sides to effectively retain internal lubrication while excluding dust, debris, and other environmental contaminants. This sealing mechanism ensures extended service life and consistent performance in demanding industrial settings without requiring frequent maintenance. Supplied in convenient packages of 50 units, these bearings offer a reliable solution for manufacturers needing bulk quantities for assembly lines or replacement inventories.
Key Features
Double metal shield construction for superior contaminant exclusion High-grade steel build ensures maximum durability and load capacity Compact 0.138-inch width ideal for tight spatial configurations Precision-ground races provide smooth rotation with minimal friction Pre-lubricated design reduces initial setup time and maintenance needs Consistent dimensional tolerances suitable for sensitive instrumentation Sold in bulk packs of 50 to support large-scale production requirements
