The SW 688-2RS miniature deep groove ball bearing is engineered for high-precision applications requiring reliable performance in confined spaces. Measuring 8mm bore (d), 16mm outer diameter (D), and 5mm width (B), this bearing features two robust rubber seals (2RS) specifically designed to retain premium grease and effectively exclude contaminants like dust, moisture, and fine particles. Constructed from high-carbon chrome steel (52100/GC15), the 688-2RS offers excellent hardness and wear resistance, ensuring low friction and smooth operation even under moderate radial and axial loads. Its sealed design makes it an ideal 'lubricated for life' solution, minimizing maintenance requirements and maximizing operational uptime in sensitive equipment.
Selecting the SW 688-2RS guarantees enhanced reliability and a reduced total cost of ownership compared to standard commercial bearings. Our industrial-grade manufacturing ensures superior quality control, resulting in lower running temperatures and reduced vibration across high-speed applications such as small electric motors, medical instrumentation, robotics, and 3D printing equipment. The tight manufacturing tolerances (typically exceeding ABEC-1 standards) provide the necessary accuracy for positioning systems, while the double-seal configuration dramatically extends service life in harsh or dirty operating environments. Trust SW engineering for critical components where precision and longevity are non-negotiable.
