671-2RS Miniature Deep Groove Ball Bearing | Sealed 1×2×1 mm for Compact Precision Equipment

671-2RS Miniature Deep Groove Ball Bearing | Sealed 1×2×1 mm for Compact Precision Equipment

The 671-2RS is a double-sealed miniature deep groove ball bearing engineered for applications demanding reliable protection in ultra-compact spaces. With its 1mm bore and 3mm outer diameter, this micro-bearing incorporates rubber contact seals to provide permanent lubrication retention and effective barrier against fine contaminants. The deep raceway geometry ensures smooth handling of light radial loads while the integrated sealing solution makes it particularly suitable for medical handpieces, precision instruments, and small electric motors where maintenance access is limited and operational reliability is paramount.

671-2RS Deep Groove Ball Bearing 1x2x1 mm | Metric Miniature Series | Double Contact Seal Configuration

Engineered for maintenance-free operation in confined installations, this bearing combines the proven deep groove architecture with integrated nitrile rubber seals. The contact seal design effectively retains specialized low-torque grease while excluding particles as small as 5-10 microns. Rated for continuous operation up to 110,000 r/min with sealed lubrication, the 671-2RS represents a optimized solution for precision rotating assemblies where contamination risk and lubrication longevity are primary design considerations.

Key Performance Features

01. Integrated Contamination Protection

The 671-2RS incorporates double nitrile rubber contact seals that provide effective labyrinth-style protection against dust, moisture, and microscopic debris. This sealing configuration extends bearing service life in environments where particulate exposure would rapidly degrade unprotected bearings, while the factory-packed premium grease ensures consistent lubrication throughout the operational lifespan.

02. Space-Optimized Load Carrying Capacity

Despite its minimal cross-section, this bearing delivers useful load capacity through optimized internal geometry and high-grade bearing steel construction. The deep groove raceway design maintains ball conformity that efficiently distributes applied loads, making it suitable for applications where bearing size is constrained but predictable rotational performance cannot be compromised.

03. Low-Torque Sealing Technology

The contact seal design incorporates advanced lip geometry that minimizes frictional torque while maintaining effective sealing action. This engineering balance ensures that the 671-2RS retains the high-speed capability expected from miniature bearings while providing the protection required for extended, maintenance-free operation in permanently assembled equipment.
