Overview
This steel deep groove ball bearing is engineered for high-speed industrial applications requiring reliable radial load support and rotational precision. Featuring a 3.15-inch bore diameter and a 4.92-inch outside diameter, the unit measures 0.87 inches in width to fit standard housing configurations found in heavy machinery. The C3 internal clearance specification is a critical design element that accommodates thermal expansion and minor shaft misalignment, ensuring consistent performance under elevated operating temperatures. Constructed from durable hardened steel, this component delivers extended service life and reduced maintenance intervals in demanding environments where structural integrity and minimal friction are paramount for operational efficiency.
Key Features
C3 internal clearance optimized for thermal expansion and high-speed rotation Hardened steel construction provides superior resistance to wear and deformation Precision-ground raceways ensure smooth operation with minimal vibration Standardized 3.15-inch bore fits common industrial shaft sizes Compact 0.87-inch width allows integration into space-constrained assemblies High radial load capacity supports heavy-duty mechanical systems Sealed design options available to protect against contamination (depending on specific variant)
