CR 61815 U Thin Section Deep Groove Ball Bearing | 75x95x10mm | High Speed & Precision

The CR 61815 U is a precision-engineered Single Row Deep Groove Ball Bearing from the extra-light 618 series, specifically designed for applications where space and weight limitations are critical. Featuring a remarkably narrow 10mm width and a thin cross-section, this bearing maximizes performance in constrained envelopes while offering superior operational characteristics. Its deep raceway geometry ensures optimal radial load support and allows for moderate axial loads in both directions. The 'U' designation typically indicates a specific seal or shield configuration, providing robust protection against particulate contaminants and retaining high-quality, factory-filled lubrication, thereby extending maintenance intervals and system reliability. Ideal for use in robotics, precision measuring equipment, aerospace components, and specialized motor applications, the 61815 U delivers exceptional running accuracy and reduced operational friction. Manufactured using high-grade bearing steel (CR standard specification), this component guarantees high fatigue life under continuous operation. By selecting the CR 61815 U, procurement and maintenance teams ensure minimal energy loss, lower operating temperatures, and sustained performance, making it a cost-effective solution for high-precision, space-critical machinery upgrades and OEM designs.
