CR 618/28 Thin Section Deep Groove Ball Bearing (28x40x7mm) | High Speed Precision
The CR 618/28 Deep Groove Ball Bearing is engineered specifically for applications demanding exceptional radial stability within extremely constrained envelope dimensions. As a crucial component in the 618 series of thin-section bearings, this unit features a 28 mm bore, 40 mm outer diameter, and a narrow 7 mm width, ensuring maximum performance density. Manufactured under strict CR quality control, the bearing utilizes high-grade bearing steel and optimized raceway geometry to deliver low friction torque, superior running accuracy, and reliable operation across a wide temperature range. This precise design makes it ideal for reducing system weight and minimizing housing dimensions without sacrificing load capacity or operational life.
Designed for demanding industrial environments, the 618/28 bearing is essential in applications such as precision instrumentation, compact electric motors, small gearboxes, and robotics where space and weight limitations are paramount. Its robust internal structure allows for handling moderate radial loads and minor axial loads in both directions. Selecting the CR 618/28 guarantees long service intervals and reduced maintenance costs, capitalizing on CR's reputation for industrial durability and precision engineering. This bearing offers the reliability necessary for mission-critical, high-speed applications where consistent rotational accuracy is non-negotiable.
