The SW 627-2RS deep groove ball bearing is engineered for exceptional reliability in challenging industrial environments where contamination is a primary concern. Featuring a 7 mm bore, 22 mm outer diameter, and 7 mm width, this precision-machined component utilizes high-quality high-carbon chromium steel (typically SAE 52100) ensuring superior hardness and wear resistance. The -2RS configuration denotes two contact-rubber seals, effectively retaining the factory-installed lithium grease and preventing the ingress of dirt, moisture, and fine particles, leading to significantly extended service life compared to open or shielded (ZZ) variants. This bearing is suitable for applications requiring both radial and moderate axial loads.
Designed for maximum operational efficiency, the SW 627-2RS is pre-lubricated for immediate deployment, reducing installation time and eliminating the risk of improper lubrication. Its low-friction design supports high-speed rotation necessary for electric motors, power tools, precision instrumentation, and small gearboxes. As a critical component in maintenance and repair operations (MRO), selecting the SW brand guarantees consistency, dimensional accuracy (P6/ABEC-3 tolerance or better), and a robust alternative to leading Tier 1 manufacturers, ensuring minimized downtime and optimal performance across critical machinery.
