| F604 | Basic bearing designation indicating metric dimensions: 4mm bore, 12mm OD, 4mm width |
| 2RS | Double rubber contact seals on both sides providing superior protection against contaminants |
F604 2rs Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured from chrome steel rings and balls with a stainless steel cage, ensuring durability and corrosion resistance. The deep groove raceway design enables efficient radial load distribution across all 7 precision balls.
Enhanced Sealing Performance: The double rubber seals (2RS) provide excellent protection against dust, moisture, and other contaminants, extending bearing service life in challenging environments. This sealing arrangement maintains lubrication integrity while preventing lubricant leakage.
Precision Engineering: Built to ABEC1 tolerance class with controlled radial internal clearance (MC3 group: 0.002mm to 0.013mm), ensuring consistent performance and smooth operation. The bearing achieves a limiting speed of 48,000 rpm, suitable for various high-speed applications.
Compact Design Advantage: The miniature bearing dimensions (4×12×4mm) combined with the integrated flange (13.5mm OD) facilitate easy mounting and secure positioning in compact assemblies.
