SKF 609-2Z Metal Shielded Single Row Deep Groove Ball Bearing 9x24x7mm

The SKF 609-2Z shielded miniature deep groove ball bearing provides smooth rotational support in machinery with limited installation space. Its 9mm bore, 24mm outside diameter and 7mm width make it suitable for compact shafts, motor housings and precision drive mechanisms. The single row deep groove construction supports radial loads and axial loads in either direction, subject to the bearing's rated capacity. SKF specifications give a basic dynamic load rating of 3.9kN and a basic static load rating of 1.66kN. Compared with the smaller 619/9 series, the 609 offers a larger bearing cross-section where sufficient housing space is available, making careful dimensional selection important.

The 2Z designation identifies metal shields fitted on both sides of the bearing. These non-contact shields help retain the factory-applied grease while restricting the entry of larger dirt particles, with less friction than contacting rubber seals. This makes the SKF 609-2Z particularly relevant to clean, enclosed mechanisms requiring low-friction rotation. SKF catalogue data lists a 34,000rpm limiting speed, although actual continuous operating suitability depends on loading, temperature, lubrication and mounting conditions. The bearing has normal (CN) radial internal clearance and a sheet steel cage. Unlike the 609-2RSH contact-sealed version, the shielded design is not intended to offer the same level of protection against fine dust or moisture. For replacement work, confirm the shield suffix, bore diameter and installation dimensions before fitting.

Typical Applications:

Small electric motors and compact drive units
