40x105x12 Deep Groove Ball Bearing - Thin Section (TSB) - CR Quality | Low Profile High Speed
This specialty 40x105x12 Deep Groove Ball Bearing is engineered for applications demanding high rotational precision within severe space limitations. Featuring a very narrow 12mm width and a large 105mm outer diameter, this bearing falls into the Thin Section category, maximizing performance while significantly reducing the overall weight and mounting envelope required. Constructed from high-carbon chrome steel (typically SAE 52100) and precision ground to standard tolerances (P0/PN), it ensures exceptional radial and moderate axial load handling. Ideal for specialized industrial machinery, robotics joints, precision pumps, and indexing tables where low inertia and reduced friction are critical design requirements.
Our CR-equivalent 40x105x12 unit delivers superior reliability and extended service life compared to standard-width bearings modified for thin applications. The unique cross-section provides high rigidity despite its minimal footprint, contributing to greater machine uptime and reduced maintenance frequency. Optimized internal geometry promotes quieter operation and allows for higher limiting speeds than comparable standard bearings. We ensure full interchangeability with major premium thin-section lines, providing a robust, cost-effective solution for upgrading legacy equipment or specifying new, highly compact drive systems.
