2217-M

The 2217-M is a high-performance self-aligning ball bearing engineered to perform reliably in applications prone to shaft deflection or mounting inaccuracies. Its defining feature is a double row of balls that roll on a common sphered raceway in the outer ring, allowing the inner ring, balls, and cage to rotate freely around the bearing center. This design enables the bearing to tolerate both static and dynamic angular misalignment. The "M" suffix indicates the presence of a machined solid brass cage, which provides superior strength and guidance for the balls, making it exceptionally durable for demanding operational conditions, including those with significant vibration, shock loads, and high acceleration.

The principal advantage of the 2217-M bearing is its inherent ability to compensate for misalignment, which reduces stress on the bearing, shaft, and housing, thereby preventing premature wear and extending the overall service life of the machinery. The solid brass cage offers enhanced reliability over standard polyamide or stamped steel cages, especially at elevated temperatures and speeds. This robust construction makes the 2217-M an ideal solution for applications in sectors such as agriculture, textiles, and industrial fans, where long shafts or separate housings can create alignment challenges. By generating less friction than other bearing types under misaligned conditions, it contributes to more efficient and cooler operation.
